Presbyopia correction lens system with hyperopia / myopia correction dependent design

Abstract

The invention relates to a presbyopia correction multifocal contact lens system with a hyperopia / myopia ametropia correction dependency design. The multifocal contact lens is part of a multifocal contact lens system ("lens system") comprising a plurality of myopic and hyperopic correction lenses each having a lower addition optical zone for presbyopia correction, and the plurality of myopia correction lenses and the plurality of hyperopia correction lenses can be selected and adapted to the patient wearer based on refractive errors thereof. To improve distant vision of a presbyopic person, a spherical aberration (SPHA) distribution, a lower addition optical zone diameter, and / or a lower addition diopter of a presbyopic corrective lens in a lens system is optimized based on presbyopic patient characteristics that may be different from myopic patient characteristics used to optimize a myopic corrective lens in the lens system. Such design optimizations may also be dependent on ametropia to further enhance distant vision.

[0001] Priority application

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 523,418, filed on June 27, 2024, and entitled “PRESBYOPIA-CORRECTING LENSSYSTEMS HAVING HYPEROPIC / MYOPIC CORRECTION-DEPENDENT DESIGNS,” the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The field of the present disclosure relates to ophthalmic lenses for correcting presbyopia. Background Art

[0004] As individuals age, the eye becomes less able to adapt or adjust the eye's natural lens to focus on objects that are relatively close to the viewer. This condition is known as presbyopia. Presbyopia is the gradual loss of the eye's ability to focus on nearby objects. Similarly, in people who have had their natural lens removed (e.g., as a result of cataract surgery), the ability to accommodate is lacking. Presbyopia typically becomes noticeable in the early 40s to mid-40s and continues to worsen until around 55 to 65 years of age.

[0005] A known method for correcting presbyopia is to use a bifocal or multifocal lens on or in the eye of the patient wearer. Multifocal lenses are designed with a specific surface shape to achieve multiple optical focal lengths. Some multifocal lenses are designed with an extended depth of focus (DOF), which "spreads" the focus along a wider range as a single elongated focus to enhance the visual range or DOF (rather than multiple optical focal lengths). Multifocal lenses can also have higher intermediate distance visual performance because their extended depth of focus (EDOF) has peak performance for intermediate distance focused objects.

[0006] For example, Figure 1 FIG. 1 is a schematic diagram of an exemplary multifocal lens 100 having multifocality and extended EDOF for correcting near vision for presbyopia and correcting intermediate and distance vision. The multifocal lens 100 has a diameter D CZ The near-center lower light addition optical zone 102 and the transition optical zones 104 (1)-104 (3) are each around the central optical axis A of the multifocal lens 100. 1The lower light-addition optical zone 102 has a lower light-addition zone power profile selected to significantly correct ametropia with a paraxial power and a lower light-addition power for correcting presbyopia. The lower light-addition optical zone 102 can be spherical or have some target spherical aberration that depends on the corrected first power in the lower light-addition optical zone 102. The transition optical zones 104(1)-104(3) each include a corresponding ametropia-correcting power profile for correcting light rays ("light") passing through the multifocal lens 100 relative to the optical axis A. 1 The outer portion of the lower light-adding optical zone 102 has different radii R C For example, each transition optical zone 104(1)-104(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. The second transition optical zone 104(2) surrounds the first transition optical zone 104(1). The third transition optical zone 104(3) surrounds the second transition optical zone 104(2) and extends to an edge 106 of the optical zone of the multifocal lens 100. The multifocal lens 100 has an overall optical zone diameter D C .

[0007] DOF is a performance measure used to optimize lens design. DOF is defined as the total range of vergence (accommodation demand) over which performance does not drop by more than 3 lines of acuity relative to peak performance. Therefore, lens design uses DOF ​​to provide adequate near performance while providing high-quality vision through focusing. For example, Figure 2A yes Figure 1 FIG. 1 is a diagram of a multifocal lens 100, showing its EDOF. Figure 2A As shown, light 200 received by the multifocal lens 100 is refracted and focused at multiple focal lengths because its diopter profile is provided by its multiple optical zones discussed above. The diopter profile of the multifocal lens 100 causes the received light 200 to be focused on an elongated focal point 202 in the EDOF 204 to enhance the visual range. This is similar to Figure 2B In contrast, the illustrated single vision lens 206 focuses received light 200 to a nominally single point 208 with a smaller DOF 210. However, multifocal lens designs typically trade off performance between distance, intermediate, and near vision. Thus, use of a multifocal lens may result in reduced visual acuity (i.e., image resolution) and image contrast at near vision compared to a single vision lens with a reader.

[0008] Figure 3 is a graph 300 showing the Figure 1 The minimum angular resolution (MAR) curve 302 of the multifocal lens 100 in FIG. 3 is a function of viewing distance in units of focal power (D). Figure 3 As shown in the through-focus visual performance curve 302 in FIG. 1 , the exemplary lens 100 achieves a DOF region 304 between approximately 0.8D and 2.6D viewing distances and an effective lower added light of approximately 0.8D.

[0009] Broadly speaking, most multifocal and EDOF lens designs can be grouped into one or a combination of two types: near center or center-distance designs. Specifically, lens designs follow one or a combination of the following design types: annular bifocal, annular multifocal, step bifocal, ramp bifocal, discontinuous aspheric, and continuous aspheric. Lens fitting guidelines follow one or a combination of the following strategies: pure simultaneous vision, improved single vision, or single lens system. In general, lens designs attempt to balance the desire for unimpaired vision through focusing with the limitations of the human binocular vision system when presented with a simultaneous vision solution. Summary of the invention

[0010] Aspects disclosed herein include presbyopia correction multifocal contact lens systems with hyperopia / myopia refractive error correction dependent designs. Related multifocal contact lens systems and patient fitting methods are also disclosed. The multifocal contact lens is part of a multifocal contact lens system ("lens system") that includes a plurality of refractive error correction dependent multifocal contact lenses that can be selected and fitted to a patient wearer based on their refractive error. As discussed in more detail below, the contact lens designs differ in effective lower light addition / or depth of focus (DOF) between myopic and hyperopic refractive errors, wherein those refractive dependency differences are driven by differences in visual optics and visual feeding for myopes and hyperopes. For example, if the patient is a myopic, a multifocal contact lens can be selected from the available lenses in the lens system based on the myopic refractive error for the patient's right eye (OD) and left eye (OS). Likewise, if the patient is hyperopic, a multifocal contact lens can be selected from the available lenses in the lens system for the patient's OD and OS based on the hyperopic refractive error. The multifocal contact lens can also include a central lower add optical zone and a peripheral transition optical zone that provides additional lower add power, thereby providing an effective lower add to correct the refractive error to correct presbyopia.

[0011] It has been found that hyperopes who are fitted with corrective lenses sometimes feel that their distance vision is impaired because they have a naturally higher expectation of superior distance vision than myopes. This is because, typically, myopes have experienced impaired distance vision due to their natural refractive error at a certain time in their lifetime and in multiple consecutive refractive error corrections (i.e., refractive error correction prescriptions). Myopes may have different expectations for using multifocal contact lenses to correct distance vision than hyperopes. It has also been found that hyperopes typically have more positive spherical aberration (SPHA) than myopes. However, if, for example, both myopia and hyperopia corrective lenses in a lens system are designed to target residual SPHAs typically observed in myopes, the hyperopia corrective lenses will produce more residual SPHA in the average hyperope. This may result in impaired distance vision in a hyperope who is fitted with a hyperopia corrective lens in a lens system compared to a myopic who is fitted with a myopia corrective lens in the same lens system. Thus, in one exemplary aspect, a hyperopia corrective lens in a lens system is designed to have a more negative SPHA than the SPHA in a myopia corrective lens in the same lens system. For example, a hyperopia corrective lens in a lens system may be designed to have a SPHA that is 10%-20% negative than the SPHA in a myopia corrective lens in the same lens system. In this way, the SPHA in the multifocal contact lenses in the lens system is better matched to the target residual SPHA for myopes and hyperopes depending on the myopia / hyperopia correction.

[0012] It has also been found that not only do hyperopes typically have more positive eye SPHA than myopes, but also that the eye SPHA of hyperopes further increases as a function of increasing refractive error. Therefore, in other exemplary aspects, the SPHA in a hyperopia corrective lens in a lens system may depend on the refractive error correction (i.e., depend on the refractive error correction prescription or the refractive error correction label diopter) to further optimize the enhanced distance vision. The SPHA of the hyperopia corrective lens depends on the refractive error correction, which means that the SPHA further varies between different hyperopia error corrections within different hyperopia corrective lenses in the lens system. For example, the SPHA of the hyperopia corrective lens in a multifocal contact lens system may be designed to add more negative SPHA to the hyperopia corrective lens as the focal power of the hyperopia refractive error correction of the hyperopia corrective lens increases. The SPHA of the myopia corrective lens in a multifocal contact lens system may also be made dependent on the refractive error correction to enhance distance vision. For example, a SPHA in a myopia corrective lens may be designed to add a more negative SPHA to the myopia corrective lens as the power of the myopia corrective prescription of the myopia corrective lens increases (ie, as the myopia corrective prescription becomes more and more negative).

[0013] For all patients, whether myopic or hyperopic, when a person focuses on a near object, their pupil size decreases, and when a person focuses on a longer distance object, their pupil size expands. However, it has been recognized that for the same or similar brightness, spherical refraction, age and convergence conditions, hyperopes generally have smaller pupils than myopes. For example, if both the myopic and hyperopic corrective lenses in a lens system are designed to have a central optical zone that simulates the average pupil size of a myopic person for presbyopia correction, this will provide greater distance vision impairment to the hyperopic person compared to a myopic person wearing a multifocal contact lens with the same or similar lower addition power from the same lens system. This is because when focusing on a long-distance object and both wearing a multifocal lens from a lens system, the larger diameter lower addition zone in the multifocal contact lens (simulating the myopic person's pupil size) intersects with a larger percentage of the hyperopic person's pupils compared to the myopic person's pupils. Thus, a hyperopic person having a smaller average pupil size than a myopic person wearing a multifocal lens from a lens system may receive less light into their pupil from the transition zone of a multifocal contact lens providing multifocality than a myopic person wearing a multifocal lens from the lens system.

[0014] Thus, in other exemplary aspects, a presbyopia correcting lens in a lens system is designed to have a near center sub-addition optical zone having a smaller optimized diameter than a near vision correcting multifocal lens in the lens system. This optimized diameter of the near center sub-addition optical zone in the presbyopia correcting multifocal lens, which depends on the myopia / hyperopia refractive error correction, increases the percentage of light received in the pupil of the presbyopic person through the transition optical zone when focusing on a distant object.

[0015] In other exemplary aspects, the diameter of the near center subaddition optical zone in a hyperopia corrective lens in a lens system may depend on the refractive error correction to further optimize enhanced distance vision. The diameter of the near center subaddition optical zone of the hyperopia corrective lens depends on the refractive error correction, which means that the diameter of the near center subaddition optical zone further varies between different hyperopia error corrections in different hyperopia corrective lenses in the lens system. For example, it has been found that as hyperopic refractive error increases, the pupil size of a hyperopic person decreases. Therefore, as an example, the diameter of the near center subaddition optical zone of the hyperopia corrective lens may be designed so that as the focal power of the hyperopia refractive error correction prescription of the hyperopia corrective lens increases, the diameter of the near center subaddition optical zone decreases. The diameter of the near center subaddition optical zone of the myopia corrective lens in the lens system may also be made dependent on the refractive error correction. For example, it has been found that the pupil size of a myopic person increases as myopic refractive error increases (i.e., as the refractive error correction becomes more and more negative). Thus, as an example, the diameter of the near central sub-addition optical zone of a myopia corrective lens may be designed such that the diameter of the near central sub-addition optical zone increases as the power of the myopic refractive error correction prescription of the myopia corrective lens decreases.

[0016] In addition, it has been found that, in general, myopia and hyperopia differ in the distribution of the lower addition diopter requirements. A higher proportion of hyperopia is fitted with high lower addition diopter lenses compared to myopia of the same or similar age. Therefore, hyperopia with higher lower addition diopter may experience greater distance vision impairment compared to myopia. Moreover, as described above, hyperopia may have a natural tendency to feel that their distance vision is impaired when fitted with presbyopia correction lenses due to the expected superior distance vision than myopia. Therefore, in an exemplary aspect, in order to improve the distance vision of hyperopia, for a given label lower addition diopter, the effective lower addition diopter in the hyperopia correction multifocal lens in the multifocal contact lens system is reduced compared to the effective lower addition diopter in the myopia correction multifocal lens in the same lens system. Moreover, by utilizing the binocular disparity between the dominant eye and the non-dominant eye of the patient, it may be desirable to reduce only the effective lower addition diopter within a specific effective lower addition diopter range of the hyperopia correction multifocal lens to improve distance vision. For example, as a non-limiting example, the effective lower add diopter may be reduced by 0.3D in a hyperopia correction multifocal lens with a medium lower add diopter (e.g., a lower add requirement of +1.5D to +1.75D), and reduced by 0.2D in a hyperopia correction multifocal lens with a high lower add diopter (e.g., a lower add requirement of +2.0D to +2.5D). The effective lower add diopter in a hyperopia correction multifocal lens in a lens system may be provided by adjusting its paraxial diopter and aspheric constant.

DETAILED DESCRIPTION

[0091] Aspects disclosed herein include presbyopia correction multifocal contact lens systems with hyperopia / myopia refractive error correction dependent designs. Related multifocal contact lens systems and patient fitting methods are also disclosed. The contact lens designs differ in effective lower light addition / or DOF between myopia and hyperopia refractive errors, wherein those refractive dependency differences are driven by differences in visual optics and visual feeding for myopes and hyperopes. The multifocal contact lens is part of a multifocal contact lens system ("lens system") that includes a plurality of refractive error correction dependent multifocal contact lenses that can be selected and fitted to a patient wearer based on their refractive error. For example, if the patient is a myopic, a multifocal contact lens can be selected from the available lenses in the lens system based on the myopic refractive error for the patient's right eye (OD) and left eye (OS). Likewise, if the patient is hyperopic, a multifocal contact lens can be selected from the available lenses in the lens system for the patient's OD and OS based on the hyperopic refractive error. The multifocal contact lens can also include a central lower add optical zone and a peripheral transition optical zone that provides additional lower add power, thereby providing an effective lower add to correct the refractive error to correct presbyopia.

[0092] In certain exemplary aspects, a hyperopia corrective lens in a lens system is designed to have a more negative spherical aberration (SPHA) than the SPHA in a myopia corrective lens in the same lens system. For example, a hyperopia corrective lens in a lens system may be designed to have a SPHA that is 10%-20% negative than the SPHA in a myopia corrective lens in the same lens system. In this way, the SPHA in the multifocal contact lens in the lens system is better matched to the target residual SPHA of myopes and hyperopes depending on the myopia / hyperopia correction. This is because it is recognized that a hyperopic person typically has a more positive SPHA than a myopic person. This may result in impaired distance vision for a hyperopic person who is fitted with a hyperopia corrective lens in a lens system compared to a myopic person who is fitted with a myopia corrective lens in the same lens system. It has also been found that hyperopes who are fitted with corrective lenses typically perceive that their distance vision is impaired because they have a naturally higher expectation of superior distance vision than myopes. This is because, typically, myopes have experienced impaired distance vision due to their natural refractive error at some time in their lives and over multiple successive refractive correction prescriptions. Myopes may have different expectations about using multifocal contact lenses to correct distance vision than hyperopes.

[0093] In other exemplary aspects, a presbyopia corrective lens in a lens system may be designed to have a near center lower light addition optical zone with a smaller optimized diameter than a near vision corrective multifocal lens in the lens system. This optimized diameter of the near center lower light addition optical zone in the presbyopia corrective multifocal lens, which depends on the correction of refractive error, increases the percentage of light received in the pupil of the presbyopic person through the transition optical zone when focusing on a distant object. This is because it is recognized that for the same or similar brightness, spherical refraction, age and convergence conditions, presbyopes generally have smaller pupils than myopes. For example, if both the near vision corrective lens and the presbyopia corrective lens in a lens system are designed to have a central optical zone that simulates the average pupil size of a myopic person for presbyopia correction, this will provide a greater distance vision impairment to the presbyopic person compared to a myopic person wearing a near center multifocal contact lens with the same or similar lower light addition power from the same lens system.

[0094] In other exemplary aspects, to improve the distance vision of a hyperopic person, for a given label lower add diopter prescription, the effective lower add diopter in a hyperopia correcting multifocal lens in a multifocal contact lens system may be reduced compared to the effective lower add diopter in a myopia correcting multifocal lens in the same lens system. This is because it is recognized that, in general, there is a difference in the distribution of lower add diopter needs between myopes and hyperopes. A higher proportion of hyperopes are fitted with high lower add diopter lenses compared to myopes of the same or similar age. Therefore, hyperopes with higher lower add diopter may experience greater distance vision impairment compared to myopes. Moreover, as described above, hyperopes may already have a natural tendency to feel that their distance vision is impaired when fitted with presbyopia correction lenses due to the expected superior distance vision than myopes. Moreover, utilizing the binocular disparity between the dominant eye and the non-dominant eye of the patient, it may be desirable to reduce only the effective lower add diopter within a certain range of effective lower add diopter of the hyperopia correction multifocal lens to improve distance vision. For example, as a non-limiting example, the effective lower add diopter may be reduced by 0.3D in a hyperopia correction multifocal lens with a medium lower add label lower add diopter (e.g., a lower add requirement of +1.5D to +1.75D), and reduced by 0.2D in a hyperopia correction multifocal lens with a high label lower add diopter (e.g., a lower add requirement of +2.0D to +2.5D). The effective lower add diopter in the hyperopia correction multifocal lens in the lens system may be provided by adjusting its paraxial diopter and aspheric constant.

[0095] Note that a presbyopia-correcting multifocal contact lens system may include some or all of the above-described properties and features.

[0096] An example of a presbyopia correcting multifocal contact lens system having a farsightedness correcting lens and a nearsightedness correcting lens is provided in Fig.11 Initially, as described below, the hyperopia correction lens and the myopia correction lens have hyperopia / myopia refractive error correction dependent designs. Before discussing these examples, the following first discusses Figure 4-10B An exemplary presbyopia-correcting multifocal contact lens system including hyperopia-correcting and myopia-correcting multifocal contact lenses that do not have a hyperopia / myopia refractive error correction dependent design is discussed.

[0097] At this point, Figure 4 4 is an exemplary multifocal contact lens system 400, which includes a respective myopia correction multifocal lens 402M (also referred to as "myopia correction lens 402M") and a hyperopia correction multifocal lens 402H (also referred to as "hyperopia correction lens 402H"), each lens having an effective lower light addition power specified with a given label lower light addition power for correcting presbyopia. In this example, myopia correction lens 402M and hyperopia correction lens 402H are multifocal contact lenses. Note that although in Figure 4 4. Only one (1) myopia corrective lens 402M and one (1) hyperopia corrective lens 402H are shown in the multifocal contact lens system 400, but the multifocal contact lens system 400 includes multiple myopia corrective lenses 402M and multiple hyperopia corrective lenses 402H, each of which has a different myopia refractive error correction indicated by a different myopia refractive error correction prescription (e.g., -1D, -2D, -3D, ..., -9D) and is used for a different label addition power, and each of which has a different hyperopia refractive error correction prescription (e.g., +1D, +2D, +3D, ..., +9D) and is used for a different label addition power. In this way, one or more myopia corrective lenses 402M and / or one or more hyperopia corrective lenses 402H can be selected for the patient's OD and OS based on the refractive error in the patient's eye to provide refractive error correction for corrective vision with multifocality and presbyopia correction.

[0098] The myopia correction lens 402M and the hyperopia correction lens 402H provide multifocality, wherein the near vision of presbyopia is corrected. Figure 4 As shown, the myopia corrective lens 402M has a myopia refractive power distribution provided by a first lower light-adding optical zone 404M and first transition optical zones 406M(1)-406M(3) surrounding the first lower light-adding optical zone 404M. In this example, the first lower light-adding optical zone 404M is a near central optical zone, which surrounds the first optical axis A. 1A first lower light-addition zone diopter distribution is provided and has a myopia correction lens 402M as part of a myopia correction lens 402M having a myopia paraxial diopter selected to significantly correct the wearer's myopia refractive error for distance vision (e.g., at 0D or 0.25D) according to the wearer's refractive error correction prescription, and having a first lower light-addition diopter for correcting presbyopia. The first lower light-addition optical zone 404M has a first lower light-addition zone diameter D C1 , whose size is based on the expected pupil contraction caused by pupil miosis when the wearer focuses on a near object (e.g., at 2.5D) to enhance presbyopia correction. In this way, when the wearer focuses on a near object, a greater percentage of light enters the wearer's pupil from the first lower light addition optical zone 404M having the first lower light addition power. The first lower light addition optical zone 404M can be spherical or have some target spherical aberration that depends on the myopic near-axis power in the first lower light addition optical zone 404M. In this example, there are three (3) first transition optical zones 406M(1)-406M(3). The first transition optical zones 406M(1)-406M(3) are arranged around the first optical axis A 1 Surrounding the first lower light-addition optical zone 404M, and each including a corresponding myopia progressive diopter distribution as part of the overall myopia diopter distribution of the myopia corrective lens 402M. The myopia diopter distribution includes the first lower light-addition zone diopter distribution, and the myopia progressive diopter distribution includes a first spherical aberration (SPHA) to provide correction of myopic refractive error.

[0099] Continue to refer Figure 4 The first transition optical zones 406M(1)-406M(3) in the myopia corrective lens 402M provide refractive correction of light rays ("light") passing through the myopia corrective lens 402M relative to the first optical axis A of the myopia corrective lens 402M. 1 The first lower light-adding optical zone 404M has different radii R outside. M1 For example, each first transition optical zone 406M(1)-406M(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. In this example, the power profiles of the first transition optical zones 406M(1), 406M(2) provide continuous power changes at their respective transitions to the respective first transition optical zones 406M(2), 406M(3). Figure 4The transitions between adjacent first transition optical zones 406M(1)-406M(3) are shown as different optical zones for illustrative purposes only, but in this example, the diopter changes at these respective transitions are continuous or substantially continuous. Thus, the myopia corrective lens 402M may have a single transition optical zone surrounding the first lower light-adding optical zone 404M and having a continuous aspheric diopter distribution diopter. Note, however, Figure 4 The transition between any adjacent first transition optical zones 406M(1)-406M(3) shown may also be discontinuous. However, note that Figure 4 The diopter change at the transition between any adjacent first transition optical zones 406M(1)-406M(3) shown may also be discontinuous. The myopia corrective lens 402M has an overall optical zone diameter D M1 .

[0100] Likewise Figure 4 As shown, the hyperopia corrective lens 402H has a hyperopia refractive power distribution provided by a second lower light-adding optical zone 404H and second transition optical zones 406H(1)-406H(3) surrounding the second lower light-adding optical zone 404H. The second lower light-adding optical zone 404H is also a near-central optical zone, which surrounds the second optical axis A. 2 A second lower light-addition zone diopter distribution is provided and has a portion of a hyperopic diopter distribution of a hyperopic corrective lens 402H, the hyperopic corrective lens having a hyperopic near-axis diopter selected to significantly correct the wearer's hyperopic refractive error for distance vision (e.g., at 0D or 0.25D) according to the wearer's refractive error correction prescription, and having a second lower light-addition diopter for correcting presbyopia. The second lower light-addition optical zone 404H also has a first lower light-addition zone diameter D C1 , which is similar in size to the first lower light-addition optical zone 404M of the myopia corrective lens 402M. This is based on the expected pupil contraction caused by pupil constriction when the wearer focuses on a near object (for example, at 2.5D) to enhance presbyopia correction. In this way, when the wearer focuses on a near object, a greater percentage of light enters the wearer's pupil from the second lower light-addition optical zone 404H having the second lower light-addition power. The second lower light-addition optical zone 404H can be spherical or have some target spherical aberration that depends on the hyperopic near-axis power in the second lower light-addition optical zone 404H. In this example, there are three (3) second transition optical zones 406H(1)-406H(3). The second transition optical zones 406H(1)-406H(3) are arranged around the second optical axis A 2Surrounding the second lower light addition optical zone 404H, and each including a corresponding hyperopic progressive diopter distribution as part of the overall hyperopic diopter distribution of the hyperopic corrective lens 402H. The hyperopic diopter distribution includes the second lower light addition zone diopter distribution, and the hyperopic progressive diopter distribution includes a second SPHA to provide correction of hyperopic refractive error.

[0101] Continue to refer Figure 4 The second transition optical zones 406H(1)-406H(3) in the hyperopia corrective lens 402H provide refractive correction of light rays ("light") passing through the hyperopia corrective lens 402H relative to the second optical axis A of the hyperopia corrective lens 402H. 2 The outer portion of the second lower light-adding optical zone 404H has different radii R H1 For example, each second transition optical zone 406H(1)-406H(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. Figure 4 The transitions between adjacent second transition optical zones 406H(1)-406H(3) are shown as distinct optical zones for illustrative purposes only, but in this example, the power changes at these respective transitions are continuous or substantially continuous. Thus, the hyperopia corrective lens 402H may have a single transition optical zone surrounding the second lower light-adding optical zone 404H and having a continuous aspheric power distribution. Note, however, that Figure 4 The transition between any adjacent second transition optical zones 406H(1)-406H(3) shown may also be discontinuous. However, note that Figure 4 The diopter change at the transition between any adjacent second transition optical zones 406H(1)-406H(3) shown may also be discontinuous. The hyperopia corrective lens 402H has an overall optical zone diameter D H1 .

[0103] Figure 5A-5C The myopia refractive power distributions 502M-A, 502M-B, 502M-C and the hyperopia refractive power distributions 502H-A, 502H-B, 502H-C of the myopia correction lens 402M and the hyperopia correction lens 402H in FIG. 4 are about the paraxial refractive power, the radius R of the first lower light-adding optical zone 404M and the second lower light-adding optical zone 404H M1 , R H1 , the effective lower light-addition diopter (i.e., the magnitude of the first lower light-addition diopter and the second lower light-addition diopter) provided by the corresponding first lower light-addition optical zone 404M and the second lower light-addition optical zone 404H, and the radius R of the first lower light-addition optical zone 404M and the second lower light-addition optical zone 404H M1 , R H1 However, for Figure 5A-5C Each lower light addition diopter group shown in the myopia refractive power distribution 502M-A, 502M-B, 502M-C and the hyperopia refractive power distribution 502H-A, 502H-B, 502H-C, the paraxial diopter, the effective lower light addition diopter provided by the corresponding first lower light addition optical zone 404M and the second lower light addition optical zone 404H (i.e., the size of the first lower light addition diopter and the second lower light addition diopter), and the radius R of the first lower light addition optical zone 404M and the second lower light addition optical zone 404H M1 , R H1 The prescription for correction of myopia and hyperopia refractive errors is relatively constant. In other words, Figure 5A-5C The given effective lower light addition diopter, the paraxial diopter, the effective lower light addition diopter of the first lower light addition optical zone 404M and the second lower light addition optical zone 404H, and the radius R shown in the different lower light addition groups of the corresponding myopia refractive power distributions 502M-A, 502M-B, 502M-C and hyperopia refractive power distributions 502H-A, 502H-B, 502H-C M1 , R H1 The prescription for correction of each of the refractive errors for myopia and hyperopia is almost the same.

[0104] Figure 6A-Figure 8F An exemplary central eye visual performance is shown, which is shown as Figure 4 Brightness (in candela (cd) per square meter (m2) of different myopia and hyperopia refractive error correction prescriptions (Rx) of the myopia correction lens 402M and the hyperopia correction lens 402H in 2 )cd / m 2 The MAR (as -10logMAR) is a function of the focal length (in units) and vergence (in units of focal power) of the lens. Figure 5A-5C The corresponding myopia refractive power distributions 502M-A, 502M-B, 502M-C and hyperopia refractive power distributions 502H-A, 502H-B, 502H-C are shown in FIG. Figure 6A-Figure 8F Plotting the central eye visual performance of the myopia corrective lens 402M and the hyperopia corrective lens 402H enables study of the overall multifocal contact lens system 400.

[0106] Figure 7A-7C are exemplary graphs 700A, 700B, 700C showing central eye visual performance as MAR (as -10 logMAR) for an off-label addition power of +0.75D, as represented by Figure 5B The corresponding middle light myopia diopter distribution in 502M-B is represented by Figure 4 A function of brightness (in candelas (cd) per square meter (m2) cd / m2) and vergence (in power) for different myopic refractive error correction prescriptions (Rx) of the myopic corrective lens 402M. Figure 7D-7F are exemplary graphs 700D, 700E, 700F showing central eye visual performance as MAR (as -10 logMAR) for an off-label addition diopter of +1.75D, as represented by Figure 5B The corresponding medium-added hyperopic diopter distribution in 502H-B is represented by Figure 4 A function of the brightness (in candelas (cd) per square meter (m2) cd / m2) and the vergence (in focal power) of the hyperopic refractive error correction prescription (Rx) of the hyperopic corrective lens 402H.

[0107] Figure 8A-8C is the labelled add diopter for +2.5D, shown as plotted luminance (cd / m 2 ) and MAR (as -10logMAR) of the central eye visual performance 800A, 800B, 800C, as represented by Figure 5C The corresponding high and low light myopia diopter distribution in 502M-C is represented by Figure 4 A function of the vergence (in units of focal power) of different myopic refractive error correction prescriptions (Rx) of the myopic corrective lens 402M. Figure 8D-Figure 8F are exemplary graphs 800D, 800E, 800F showing central eye visual performance as MAR (as -10 logMAR) for an off-label addition power of +2.5D, as represented by Figure 5C The corresponding high and low light hyperopia diopter distribution in 502H-C is represented by Figure 4 A function of the brightness (in candelas (cd) per square meter (m2) cd / m2) and the vergence (in focal power) of the hyperopic refractive error correction prescription (Rx) of the hyperopic corrective lens 402H.

[0108] Figure 4It has been noted that there is a difference in the central eye visual performance between the myopia corrective lens 402M and the hyperopia corrective lens 402H in the multifocal contact lens system 400. For example, Figure 6A-6C As shown in the central eye visual performance graphs 600A-600C in FIG. 4 , there is little difference in central eye visual performance for the myopia corrective lens 402M with a lower label addition power of +0.75D for -9D, -6D, and -3D refractive error correction prescriptions. Figure 6A-6C As shown, for each of the -9D, -6D, and -3D (Rx) refractive error correction prescriptions of the myopia correction lens 402M, at a level above 80 cd / m 2 At brightness levels of -.025 or higher, high visual acuity is achieved for distance, intermediate, and near vision until the focus approaches approximately 2.5D or greater for near vision. This is substantially the same for the central eye visual performance of the hyperopia corrective lens 402H with +2D, +4D, and +6D (Rx) refractive error correction prescriptions (Rx) having a lower off-label addition power of +0.75D. Figure 6D-6F As shown, for each of the refractive error correction prescriptions of +2D, +4D, and +6D (Rx) of the hyperopia corrective lens 402H having an under-label addition power of +0.75D, at a temperature above 80 cd / m 2 At uniform brightness levels, visual acuity better than 0 (-10 logMAR) for 20 / 20 vision is achieved for distance, intermediate, and near vision until the focus approaches approximately 2.5D or greater in near vision.

[0109] However, if Figure 7A-7C and Figure 7D-7F As shown in the central eye visual performance curves 700A-700C and 700D-700F of the respective myopia corrective lens 402M and hyperopia corrective lens 402H having a label addition power of +1.75D, the distance central eye visual performance is significantly reduced in an undesirable manner. For example, as shown in the corresponding Figure 7A-7C As shown in the graphs 700A-700C in FIG. 7 , for the myopia correction lens 402M having a +1.75D lower addition power, the 80 cd / m 2 A visual acuity of better than 0 (-10 logMAR) for 20 / 20 vision is achieved at a brightness level of Figure 7D-7FAs shown in the graphs 700D-700F in FIG. 7 , for the hyperopia corrective lens 402H having a +1.75D lower addition power, the 80 cd / m 2 Visual acuity better than 0 (-10 logMAR) for 20 / 20 vision was achieved at brightness levels of 10.

[0110] Moreover, if Figure 8A-8C and Figure 8D-Figure 8F As shown in the central eye visual performance curves 800A-800C and 800D-800F of the respective myopia corrective lens 402M and hyperopia corrective lens 402H having a label addition power of +2.5D, the near and far distance central eye visual performance is significantly reduced in an undesirable manner. For example, as shown in the corresponding Figure 8A-8C As shown in the graphs 800A-800C in FIG. 8 , for the myopia correction lens 402M having a +2.5D lower addition power, the 80 cd / m 2 A visual acuity of better than 0 (-10 logMAR) for 20 / 20 vision is achieved at a brightness level of Figure 8D-Figure 8F As shown in the graphs 800D-800F in FIG. 8 , for the hyperopia corrective lens 402H having a +2.5D lower addition power, the 80 cd / m 2 Visual acuity better than 0 (-10 logMAR) for 20 / 20 vision was achieved at brightness levels of 10.

[0111] It has been found that hyperopes who are fitted with corrective lenses sometimes perceive their distance vision to be impaired because they have a naturally higher expectation of superior distance vision than myopes. This is because, typically, myopes have experienced impaired distance vision due to their natural refractive error at some time in their lifetime and over multiple successive refractive correction prescriptions. Figure 4 Myopia correction lenses 402M may not be suitable for myopic patients who wear Figure 4 The hyperopic person wearing the hyperopia corrective lenses 402M, 402H in FIG. 4 has the same expectation for corrected distance vision using multifocal contact lenses.

[0112] It has also been found that hyperopes generally have more positive SPHA than myopes. SPHA varies with spherical refraction, age (and therefore the need for add power), and vergence. Fig. 9A and Fig. 9B900A, 900B, which show the corresponding average eye SPHA (in D per square millimeter (mm)) in myopes and hyperopes as a function of the refractive error correction prescription (Rx) and the down-addition diopter requirement. 2 )(D / mm 2 ), where the diopter requirement increases with age. Fig. 9A As shown in the graph 900A for myopes, the average myopic subject with a refractive error correction prescription (Rx) of -3.25D and a down-addition diopter requirement of +1.75D has a refractive error of 0.077D / mm 2 However, if Fig. 9B As shown in graph 900B for hyperopes, the average hyperopic subject with a +2.0D refractive error correction prescription (Rx) and a +2.25D add diopter requirement has a refractive error of 0.089 D / mm. 2 The expected eye SPHA.

[0113] Therefore, if the myopia correction lens 402M and the hyperopia correction lens 402H are designed to have a myopia and hyperopia diopter distribution of -0.080D / mm 2 If a SPHA of -0.003D / mm is used, this will provide a myopic subject with a -3.25D refractive error correction prescription (Rx) and a +1.75D add diopter requirement of -0.003D / mm 2 Residual SPHA (i.e., 0.077D / mm 2 -0.080D / mm 2 ), the myopic subject had 0.077 D / mm 2 However, this would provide 0.009 D / mm for a hyperopic subject with a +2D refractive error correction prescription (Rx) and a +2.25D add diopter requirement. 2 Higher residual SPHA (i.e., 0.089 D / mm 2 -0.080D / mm 2 ). Therefore, the hyperopia corrective lens 402H will cause the average hyperopic person to have more residual SPHA than the average myopic person, thereby impairing the distance vision of the hyperopic person. Therefore, it has been found that having a method of using a target SPHA based on the myopic person Figure 4 The design of the multifocal contact lens system 400 with the myopia correction lens 402M and the hyperopia correction lens 402H results in the same Figure 4 Compared to a myopic person wearing myopia corrective lens 402M in the multifocal contact lens system 400, a hyperopic person wearing hyperopia corrective lens 402H in the same multifocal contact lens system 400 has impaired distance vision.

[0114] It has also been found that for the same or similar conditions of brightness, spherical refraction, age, and vergence, hyperopes generally have smaller pupils than myopes. Figure 4 The myopia correction lens 402M and the hyperopia correction lens 402H in the multifocal contact lens system 400 each have a first optical lower light addition optical zone 404M and a second optical lower light addition optical zone 404H (both designed to have a first lower light addition zone diameter D that simulates the average pupil size of a myopic person). C1 In the case of a multifocal contact lens system 400 for presbyopia correction, this may provide a greater impairment of distance vision to a hyperopic person than a myopic person wearing a myopia correction lens 402M and a hyperopia correction lens 402H with the same or similar lower addition power in the same multifocal contact lens system 400. Fig. 10A and Fig. 10B , which show the corresponding mean entrance pupil diameter in millimeters (mm) as a function of the refractive error correction prescription (Rx) and the down-addition diopter requirement in myopes and hyperopes. Fig. 10A As shown in the graph 1000A for myopia, the patient has a refractive error correction prescription (Rx) of -3.25D and a down-addition diopter requirement of +1.75D and a 120cd / m 2 The average myopic subject with a brightness and 2D vergence has an expected entrance pupil diameter of 2.428 mm. Fig. 10B As shown in the graph 1000B for a hyperopic patient, the patient has a +2.0D refractive error correction prescription (Rx) and a +2.25D add diopter requirement and a 120 cd / m 2 The average hyperopic subject with brightness and 2D vergence has an expected entrance pupil diameter of 2.251 mm.

[0115] Therefore, if Figure 4 The diameter D of the first lower light addition zone of the second lower light addition optical zone 404H of the hyperopia correction lens 402H in the multifocal contact lens system 400 is C1 Designed for presbyopia correction for the average pupil size of myopes, this provides a greater distance vision impairment for a hyperope wearing a hyperopia correction lens 402H than for a myope wearing a myopia correction lens 402M from the same multifocal contact lens system 400. This is because when wearing the lenses of the myopia correction lens 402M or the hyperopia correction lens 402H in the same multifocal contact lens system 400, when focusing on a distant object, the larger first lower light addition zone diameter D of the second lower light addition optical zone 404H in the hyperopia correction lens 402H is larger than the pupil of the myope. C1Thus, the pupils of hyperopes, whose average size is smaller than that of myopes, may receive a lower percentage of light from the second transitional optical zones 406H(1)-406H(3) of the hyperopic corrective lens 402H that provide multifocality, compared to myopes wearing the myopia corrective lens 402M from the same multifocal contact lens system 400.

[0116] It is therefore desirable to provide a multifocal contact lens system comprising a myopia corrective lens and a hyperopia corrective lens having multiple different ametropia correction prescriptions for vision correction and a lower light addition power for presbyopia correction, but wherein the design provides the freedom to vary the SPHA and / or lower light addition optical zone diameter of the hyperopia corrective lens relative to the myopia corrective lens to provide improved distance vision to the hyperopic person.

[0117] At this point, Fig.11 An exemplary multifocal contact lens system 1100 is shown, which includes respective myopia-correcting multifocal lenses 1102M (referred to herein as "myopia-correcting lenses 1102M") and hyperopia-correcting multifocal lenses 1102H (referred to herein as "hyperopia-correcting lenses 1102H"). In this example, myopia-correcting lenses 1102M and hyperopia-correcting lenses 1102H are multifocal contact lenses. Myopia-correcting lenses 1102M and hyperopia-correcting lenses 1102H also each have an effective lower add power for correcting presbyopia specified with a given label lower add power. Note that although in Fig.11 Only one (1) myopia correction lens 1102M and one (1) hyperopia correction lens 1102H are shown, but the multifocal contact lens system 1100 includes multiple myopia correction lenses 1102M and multiple hyperopia correction lenses 1102H, each of the myopia correction lenses having a different myopia correction indicated by a different myopia correction prescription (e.g., -1D, -2D, -3D, ..., -9D) and used for different label addition powers, and each of the hyperopia correction lenses having a different hyperopia correction prescription (e.g., +1D, +2D, +3D, ..., +9D) and used for different label addition powers.

[0118] As discussed in more detail below, in one example, to improve the distance vision of a hyperopic person wearing a hyperopia corrective lens 1102H in a multifocal contact lens system 1100, the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 is designed to have a SPHA that is more negative than the SPHA in the myopia corrective lens 1102M in the same multifocal contact lens system 1100. For example, the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 may be designed to have a SPHA that is 10%-20% negative than the SPHA in the myopia corrective lens 1102M in the same multifocal contact lens system 1100. In this way, the SPHA in the myopia corrective lens 1102M and the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 is better matched to the target residual SPHA of the myopic and hyperopic persons depending on the myopia / hyperopia correction.

[0119] As discussed in more detail below, in another example, in order to improve the distance vision of a hyperopic person wearing a hyperopia corrective lens 1102H in a multifocal contact lens system 1100, the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 is designed to have a central lower light-addition optical zone with a smaller optimized diameter than the myopia corrective lens 1102M in the multifocal contact lens system 1100. This is based on the finding that hyperopics typically have smaller pupils than myopes for the same or similar brightness, spherical refraction, age, and vergence conditions. This smaller optimized diameter of the central lower light-addition optical zone in the hyperopia corrective lens 1102H increases the percentage of light received in the hyperopic person's pupil through its transition optical zone when focusing on distant objects. This is in contrast to alternative hyperopia corrective lenses (such as Figure 4 The alternative hyperopia corrective lens has a diameter size of the central lower light addition optical zone in the myopia corrective lens 402M in the multifocal contact lens system 400 optimized for myopia. In the multifocal contact lens system 400, when focusing on a distant object, the percentage of light received in the pupil of the hyperopia through the transition optical zone of the hyperopia corrective lens 402H is reduced compared to the pupil of the myopia wearing the myopia corrective lens 402M, thereby causing the hyperopia's distance vision to be more impaired.

[0120] In this way, one or more myopia corrective lenses 1102M and / or one or more hyperopia corrective lenses 1102H can be selected from the multifocal contact lens system 1100 for the patient's OD and OS based on the refractive error in the patient's eye to provide refractive error correction for corrective vision and improved longer distance vision for hyperopes with multifocality and presbyopia correction.

[0121] refer to Fig.11, the myopia correction lens 1102M and the hyperopia correction lens 1102H provide multifocality, wherein the near vision of presbyopia is corrected. Fig.11 As shown, the myopia corrective lens 1102M has a myopia refractive power distribution provided by a first lower light-adding optical zone 1104M and first transition optical zones 1106M(1)-1106M(3) surrounding the first lower light-adding optical zone 1104M. The myopia corrective lens 1102M may also have a farthest distance optical zone 1106M(F) surrounding the first transition optical zone 1106M(3) having a refractive correction power for distance vision. As a non-limiting example, the myopia corrective lens 1102M may have a myopia refractive power distribution provided by a first lower light-adding optical zone 1104M and first transition optical zones 1106M(1)-1106M(3) surrounding the first lower light-adding optical zone 1104M. Figure 4 The first lower light-adding optical zone 1104M is designed around the first optical axis A. 1 A first lower light-addition zone diopter distribution is provided and has a myopia correction lens 1102M as part of a myopia correction lens 1102M having a myopia paraxial diopter selected to significantly correct the wearer's myopia refractive error for distance vision (e.g., at 0.25D) according to the wearer's refractive error correction prescription, and having a first lower light-addition diopter for correcting presbyopia. The first lower light-addition optical zone 1104M has a first lower light-addition zone diameter D C1 , whose size is based on the expected pupil contraction caused by pupil miosis when the wearer focuses on a near object (e.g., at 2.5D) to enhance presbyopia correction. In this way, when the wearer focuses on a near object, more light enters the wearer's pupil from the first lower light addition optical zone 1104M having the first lower light addition diopter. The first lower light addition optical zone 1104M can be spherical or have some target spherical aberration that depends on the myopic near-axis diopter in the first lower light addition optical zone 1104M. In this example, there are three (3) first transition optical zones 1106M(1)-1106M(3). The first transition optical zones 1106M(1)-1106M(3) are arranged around the first optical axis A 1 Surrounding the first lower light-addition optical zone 1104M; each transition optical zone includes a corresponding myopia progressive diopter distribution as part of the overall myopia diopter distribution of the myopia correction lens 1102M. The myopia diopter distribution includes the first lower light-addition zone diopter distribution, and the myopia progressive diopter distribution includes a first spherical aberration (SPHA) to provide correction of myopia refractive error correction.

[0122] The first transition optical zones 1106M(1)-1106M(3) in the myopia corrective lens 1102M provide refractive correction of light rays ("light") passing through the myopia corrective lens 1102M relative to the first optical axis A of the myopia corrective lens 1102M. 1The first lower light-adding optical zone 1104M has different radii R outside. M2 For example, each first transition optical zone 1106M(1)-1106M(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. In this example, the power profiles of the first transition optical zones 1106M(1), 1106M(2) provide discontinuous or derivative discontinuous power changes at their respective transitions to the respective first transition optical zones 1106M(2), 1106M(3). Fig.11 The transitions between adjacent first transition optical zones 1106M(1)-1106M(3) are shown as different optical zones for illustrative purposes only, but in this example, the diopter changes at these respective transitions are continuous or substantially continuous. Thus, the myopia corrective lens 1102M may have a single transition optical zone surrounding the first lower light-adding optical zone 1104M and having a continuous aspheric diopter distribution diopter. Note, however, Fig.11 The transition between any adjacent first transition optical zones 1106M(1)-1106M(3) shown may also be discontinuous. However, note that Fig.11 The diopter change at the transition between any adjacent first transition optical zones 1106M(1)-1106M(3) shown may also be discontinuous. The myopia corrective lens 1102M has an overall optical zone diameter D M1 .

[0123] Likewise Fig.11 As shown, the hyperopia correction lens 1102H has a hyperopia refractive power distribution provided by the second lower light-adding optical zone 1104H and the second transition optical zones 1106H(1)-1106H(3) surrounding the second lower light-adding optical zone 1104H. The hyperopia correction lens 1102H may also have a farthest distance optical zone 1106H(F) surrounding the third second transition optical zone 1106H(3) having a refractive correction power for far vision. The second lower light-adding optical zone 1104H surrounds the second optical axis A. 2 A second lower light-addition zone diopter distribution is provided and has a second lower light-addition zone diopter distribution as part of a hyperopia diopter distribution of a hyperopia corrective lens 1102H, the hyperopia corrective lens having a hyperopia paraxial diopter selected to significantly correct the wearer's hyperopia refractive error for distance vision (e.g., at 0.25D) according to the wearer's refractive error correction prescription, and having a second lower light-addition diopter for correcting presbyopia. In this example, the second lower light-addition optical zone 1104H has a second lower light-addition zone diameter D C2 , whose size is smaller than the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 1104M of the myopia correction lens 1102M C1This is based on the expected reduced pupil size of a hyperopic wearer when the pupil constricts to miosis when the wearer focuses on a near object (e.g., at 2.5D) compared to a myopic wearer of myopic corrective lens 1102M.

[0124] The second lower light-addition optical zone 1104H may be spherical or have some target spherical aberration depending on the hyperopic near-axis diopter in the second lower light-addition optical zone 1104H. In this example, there are three (3) second transition optical zones 1106H(1)-1106H(3). The second transition optical zones 1106H(1)-1106H(3) are arranged around the second optical axis A. 2 Surrounding the second lower light-addition optical zone 1104H; each transition optical zone includes a corresponding hyperopic progressive diopter distribution as part of the overall hyperopic diopter distribution of the hyperopic corrective lens 1102H. The hyperopic diopter distribution includes the second lower light-addition zone diopter distribution, and the hyperopic progressive diopter distribution includes a second spherical aberration (SPHA) to provide correction of hyperopic refractive error correction.

[0125] Continue to refer Fig.11 The second transition optical zones 1106H(1)-1106H(3) in the hyperopia corrective lens 1102H provide refractive correction of light rays ("light") passing through the hyperopia corrective lens 1102H relative to the second optical axis A of the hyperopia corrective lens 402H. 2 The outside of the center-second lower light-adding optical zone 1104M has different radii R H2 For example, each second transition optical zone 1106H(1)-1106H(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. Fig.11 The transitions between adjacent second transition optical zones 1106H(1)-1106H(3) are shown as different optical zones for illustrative purposes only, but in this example, the diopter changes at these respective transitions are continuous or substantially continuous. Thus, the hyperopia corrective lens 1102H may have a single transition optical zone surrounding the second lower light-adding optical zone 1104H and having a continuous aspheric diopter distribution diopter. Note, however, Fig.11 The transition between any adjacent second transition optical zones 1106H(1)-1106H(3) shown may also be discontinuous. However, note that Fig.11 The diopter change at the transition between any adjacent second transition optical zones 1106H(1)-1106H(3) shown may also be discontinuous. The hyperopia corrective lens 1102H has an overall optical zone diameter D H1 .

[0126] Moreover, if Fig.11As shown and discussed in more detail below, the myopia power distribution in each myopia corrective lens 1102M in the multifocal contact lens system 1100 has a first SPHA 1112M that is larger than a second SPHA 1112H in each hyperopia power distribution of the hyperopia corrective lens 1102H in the multifocal contact lens system 1100. In other words, the first SPHA 1112M is the same in each myopia corrective lens 1102M in the multifocal contact lens system 1100, but the second SPHA 1112H is the same but smaller than the first SPHA 1112M in each hyperopia corrective lens 1102H in the multifocal contact lens system 1100. The first SPHA 1112M in the myopia corrective lens 1102M is a spherical aberration in the myopia power distribution of the myopia corrective lens 1102M as a function of their relative to the first optical axis A. 1 The radius R M2 The second SPHA 1112H in the hyperopia corrective lens 1102H is a spherical aberration in the hyperopia refractive power distribution of the hyperopia corrective lens 1102H as a function of their relative to the second optical axis A. 2 The radius R H2 Reducing the second SPHA 1112H in the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 relative to the first SPHA 1112M in the myopia corrective lens 1102M in the multifocal contact lens system 1100 can further improve the distance vision of a hyperopic person wearing the hyperopia corrective lens 1102H in the multifocal contact lens system 1100. For example, the second SPHA 1112H can be at least ten percent (10%) smaller than the first SPHA 1112M because it is found that, on average, hyperopics have smaller SPHAs than myopes for similar spherical refraction, age, vergence, and lower add power requirements. As another example, the second SPHA 1112H of the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 may be ten percent (10%) to twenty percent (20%) smaller than the first SPHA 1112M in the myopia corrective lens 1102M in the multifocal contact lens system 1100 .

[0127] In another example, the first SPHA 1112M of each lens in the plurality of myopia corrective lenses 1102M is an average first eye SPHA for a myopic population, such as Fig. 9A The second SPHA 1112H of each lens in the plurality of hyperopia corrective lenses 1102H can also be targeted at the average second eye SPHA of the hyperopia group, such as Fig. 9B As shown in graph 900B.

[0128] In another example, the second SPHA 1112H in the plurality of hyperopia corrective lenses 1102H in the multifocal contact lens system 1100 may be provided with the same target residual SPHA as the first SPHA 1112M in the myopia corrective lens 1102M in the multifocal contact lens system 1100. For example, as previously described with respect to Fig. 9A As discussed, for an average myopic subject with a myopic refractive error correction prescription of -3.25D and an off-label add diopter requirement of +1.75D, the expected value of the distance SPHA may be 0.077D / mm2. The myopic correction lens 1102M in the multifocal contact lens system 1100 may have a correction factor providing -0.080D / mm 2 The myopic power distribution of the first SPHA 1112M results in = -0.003D / mm 2 Residual ocular SPHA (i.e., 0.077 D / mm 2 -0.080D / mm 2 ).like Fig. 9B As shown, for an average hyperopic subject with a hyperopic refractive error correction prescription = +2.00D and an off-label addition diopter requirement = +2.25D, the expected value of the distance SPHA is 0.089D / mm 2 Therefore, in order to match the target residual SPHA of the hyperopic group wearing the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 with the myopic group wearing the myopia corrective lens 1102M, the design of the hyperopia corrective lens 1102H in this example is changed so that their second SPHA 1112H is -0.092D / mm 2 (i.e., -0.089D / mm 2 -0.003D / mm 2 =-0.092D / mm 2 ) to provide the same target residual SPHA in the hyperopic group.

[0129] In another example, the first SPHA 1112M in each myopia corrective lens 1102M is the same in the multifocal contact lens system 1100, but the first SPHA 1112M is a radius R of the myopia corrective lens 1102M. M2 For example, the first SPHA 1112M of each myopia corrective lens 1102M may be -0.064D / mm 2 and -0.096D / mm 2 The second SPHA 1112H in each hyperopia corrective lens 1102H is the same in the multifocal contact lens system 1100, but the second SPHA 1112H is also the radius R of the hyperopia corrective lens 1102H. H2For example, the second SPHA 1112H of each hyperopia correction lens 1102H may be -0.073D / mm 2 and -0.111D / mm 2 between.

[0130] As described above, the second lower light-adding optical zone 1104H of the hyperopia correction lens 1102H also has a second lower light-adding zone diameter D C2 , whose size is smaller than the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 1104M of the myopia correction lens 1102M C1 This is based on the expected reduced pupil size of a presbyopic wearer as the pupil constricts to miosis when the wearer focuses on a near object (e.g., at 2.5D). In this way, when the presbyopic wearer focuses on a distant object, more light enters the pupil of the presbyopic wearer from the second transition optical zones 1106H(1)-1106H(3) to provide improved longer distance vision.

[0131] This is Fig.12 As shown in Fig.11 The myopia corrective lens 1102M and the hyperopia corrective lens 1102H of the multifocal contact lens system 1100 in FIG. 1 are shown worn on respective myopes and hyperopes at the same brightness, spherical refraction, age, vergence, and down-add power requirements as an example of shorter distance vision when focusing on shorter distance objects. Fig.12 As shown, when the corresponding myopia correction lens 1102M and hyperopia correction lens 1102H are worn under the same or similar conditions of brightness, spherical refraction, age, vergence and lower added diopter, the diameter D of the pupil 1010M of the myopic person is MP Greater than the diameter D of the pupil 1010H of a hyperopic person HP This is because, on average, a hyperopic pupil will contract more to a smaller diameter size than a myopic pupil under similar conditions. Fig.11 and Fig.12 As shown and discussed in more detail below, the second lower light-adding optical zone 1104H of the hyperopia corrective lens 1102H has a second lower light-adding zone diameter D C2 , whose size is smaller than the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 1104M of the myopia correction lens 1102M C1 , which is based on the expected reduced pupil size of a presbyopic wearer when the presbyopic wearer constricts to miosis when the wearer focuses on a near object (e.g., at 2.5D).

[0132] For example, as mentioned above Fig. 10A As discussed in the graph 1000A, at 120 cd / m 2In the case of brightness and 2D of vergence, the expected value of the entrance pupil diameter for an average myopic subject with a myopic refractive error correction prescription of -3.25D and a label add diopter requirement of +1.75D may be 2.428mm. The myopia corrective lens 1102M may have its first label add optical zone 1104M and its first transition optical zone 1106M(1)-1106M(3), which are defined by radial control positions [0, 0.7831, 1.0569, 1.4895] for the medium label add diopter myopia corrective lens 1102M and radial control positions [0, 0.6389, 0.9426, 1.4337] for the high label add diopter myopia corrective lens 1102M. As described above in Fig.11 As discussed in the graph 1000B in FIG. 1000B, also at 120 cd / m 2 In the case of 2D of brightness and 2D of vergence, the expected value of the entrance pupil diameter for an average hyperopic subject with a +2.00D hyperopic refractive error correction prescription and a +2.25D label addition diopter requirement can be 2.251mm. Therefore, in the example, in order to match the target relative lower addition zone size of the myopic group, the design of the hyperopic correction lens 1102H in the multifocal contact lens system 1100 can be changed so that the radial control point is reduced by 2.251 / 2.428=0.927 times, so that the second lower addition zone diameter D of the second lower addition optical zone 1104H is C2 The diameter D of the second lower light-adding zone of the first lower light-adding optical zone 1104M in the myopia correction lens 1102M is C2 As another example, the diameter D of the second lower light-adding zone of the second lower light-adding optical zone 1104H of the hyperopia correction lens 1102H is C2 The diameter D of the first lower light-adding area of ​​the comparable myopia correction lens 1102M C1 At least five percent (5%) smaller (eg, seven percent (7%) smaller).

[0133] Therefore, in this example, the diameter D of the first lower light-adding area of ​​the myopia correction lens 1102M is C1 and the diameter D of the second lower light-adding area of ​​the hyperopia correction lens 1102H C2 It can be based on the targeted average pupil diameter of the corresponding myopic and hyperopic populations. This can be obtained, for example, from the above Fig. 10A and Fig. 10B The graphs 1000A and 1000B in FIG.

[0134] In addition, it has been found that, in general, there is a difference in the distribution of lower add diopters required for myopia and hyperopia. A higher proportion of hyperopia are fitted with high lower add diopters lenses compared to myopia of the same or similar age. Therefore, hyperopia with higher lower add diopters may experience greater distance vision impairment compared to myopia. Moreover, as described above, hyperopia may already have a natural tendency to feel that their distance vision is impaired when fitted with presbyopia correction lenses due to the expected superior distance vision than myopia. Therefore, in an exemplary aspect, in order to improve the distance vision of a hyperopia, for a given labeled lower add diopters, the effective lower add diopters in the hyperopia correction lens 1102H in the multifocal contact lens system 1100 may also be reduced compared to the effective lower add diopters in the myopia correction lens 1102M of the same multifocal contact lens system 1100. Moreover, utilizing the binocular disparity between the dominant and non-dominant eyes of the patient, it may be desirable to reduce the effective lower add diopter within only certain effective label lower add diopter ranges of the hyperopia correcting multifocal lens 1102H to improve distance vision. For example, for a given label lower add diopter, the effective lower add diopter in some or all of the hyperopia correcting lenses 1102H may be reduced compared to the label lower add diopter of the myopia correcting lens 1102M. The effective lower add diopter in the hyperopia correcting lens 1102H in the multifocal contact lens system 1100 may be provided by adjusting its paraxial diopter and the aspheric constant in its corresponding hyperopia diopter profile.

[0135] For a given label addition power, the DOF of one or more hyperopia corrective lenses 1102H may vary by +0.05D to -0.25D relative to the DOF of one or more myopia corrective lenses 1102M for the same given label addition power.

Note, however, that the low lower add label lower add power can be between +0.5D and +1.49D.

Note, however, that the medium lower add label lower add power can be between +1.5 D and +1.99 D.

Note, however, that the high and low add label diopter can be between +2.0D and +2.5D.

In other words, Figure 13A-13CThe given effective lower addition diopter, the paraxial diopter, the effective lower addition diopter and the radius R of the first lower addition optical zone 1104M are shown in the different labeled lower addition diopter groups of the corresponding low lower addition, medium lower addition and high lower addition myopic diopter distributions 1302M-A, 1302M-B, 1302M-C M1 The prescription for correction of refractive error for myopia is almost the same for each.

[0139] Figure 13D-13FThe low lower addition, medium lower addition and high lower addition hyperopic diopter distributions 1302H-D, 1302H-E and 1302H-F of the hyperopic correction lens 1102H in FIG. 1 are about the paraxial diopter and the radius R of the second lower addition optical zone 1104H. H2 , the effective lower light-addition diopter provided by the second lower light-addition optical zone 1104H (ie, the size of the second lower light-addition diopter), and the radius R of the second lower light-addition optical zone 1104H H2 However, for Figure 13D-13F The lower light addition diopter group of each low lower light addition, medium lower light addition and high lower light addition label shown in the low lower light addition, medium lower light addition and high lower light addition hyperopia diopter distribution 1302H-D, 1302H-E, 1302H-F, the paraxial diopter, the effective lower light addition diopter provided by the second lower light addition optical zone 1104H (i.e., the size of the second lower light addition diopter) and the radius R of the second lower light addition optical zone 1104H H2 The hyperopic refractive error correction prescription is relatively constant. In other words, Figure 13D-13F The given effective lower addition diopter, the paraxial diopter, the effective lower addition diopter and the radius R of the second lower addition optical zone 1104H are shown in the different labeled lower addition diopter groups of the corresponding low lower addition, medium lower addition and high lower addition hyperopia diopter distributions 1302H-D, 1302H-E, 1302H-F. H2 The prescription for correction of refractive error for myopia is almost the same for each.

[0140] As described above, the effective lower add diopter (e.g., paraxial diopter) of the hyperopia corrective lens 1102H can be reduced relative to the effective label diopter (e.g., paraxial diopter) of the myopia corrective lens 1102M to further improve the distance vision of the hyperopic person wearing the hyperopia corrective lens 1102H. This is achieved, for example, by comparing Fig.13A and Fig.13D The corresponding low light label of the low light addition myopia correction lens 1102M and the low light addition hyperopia correction lens 1102H are shown as low light addition myopia refractive power distribution 1302M-A and low light addition hyperopia refractive power distribution 1302H-D. This is also described in more detail below Figures 14A-14D As shown in Tables 1400A-1400D, they show that for 9 cd / mm as shown in FIG. 2 、36cd / mm 2 、120cd / mm 2 and 400cd / mm 2 The various corresponding brightness, and Figure 4 Compared to the hyperopia corrective lens 402H in the multifocal contact lens system 400, Fig.110046] Corresponding exemplary monocular effective lower add diopters (in units of focal length) for the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 in FIG.

[0141] For example, Fig.13D The low-addition label addition power of one or more low-addition hyperopia corrective lenses 1102H shown by their low-addition hyperopia power distribution 1302H-D is relative to Fig.13A The low add label power of one or more low add myopia corrective lenses 1102M shown by their low add myopia power distribution 1302M-A in FIG. 1 may be reduced from 0D to +0.15D. For example, this is also achieved by comparing Fig. 13B and Fig.13E The corresponding middle lower light addition labels in the middle lower light addition diopter of the myopia correction lens 1102M and the hyperopia correction lens 1102H are shown as middle lower light addition diopter distribution 1302M-B and middle lower light addition diopter distribution 1302H-E. For example, Fig.13E The middle lower addition label lower addition diopter of one or more middle lower addition hyperopia corrective lenses 1102H shown by their middle lower addition hyperopia diopter distributions 1302H-E is relative to Fig. 13B The mid-addition label diopter of one or more mid-addition myopia corrective lenses 1102M shown by their mid-addition myopia diopter distribution 1302M-B may be reduced by +0.20D to +0.50D. For example, this is also achieved by comparing Fig. 13C and Fig.13F The corresponding high and low light addition labels in the myopia correction lens 1102M and the hyperopia correction lens 1102H are shown as high and low light addition myopia diopter distribution 1302M-C and high and low light addition hyperopia diopter distribution 1302H-F. For example, Fig.13F The high and low addition labels of one or more high and low addition hyperopia corrective lenses 1102H shown by their high and low addition hyperopia diopter distributions 1302H-F are shown relative to Fig. 13C The high and low addition label lower light addition diopter of one or more high and low addition myopia corrective lenses 1102M shown by their high and low addition myopia diopter distributions 1302M-C may be reduced by +0.15D to -0.15D.

[0142] For example, in Fig.11 In the multifocal contact lens system 1100, Fig.13E The effective middle lower light addition diopter (e.g., at least +1.5D (e.g., +1.5D to +1.75D lower light addition requirement)) in the middle lower light addition hyperopia refractive power distribution 1302H-E of the middle lower light addition hyperopia corrective lens 1102H shown is Fig. 13BThe middle lower light myopia refractive power distribution 1302M-B in the middle lower light myopia correction lens 1102M can be reduced by at least +0.2D compared to the corresponding middle lower light myopia correction lens 1102M. Fig.13F The effective high lower add diopter (e.g., lower add requirement of +2.0D to +2.5D) in the intermediate lower add hyperopia refractive power distribution 1302H-E in the hyperopia corrective lens 1102H shown is compared with Fig. 13C The high and low light addition myopia refractive power distribution 1302M-C in the figure can be reduced by at least +0.2D (for example, a low light addition requirement of +0.3D) compared to the corresponding high and low light addition myopia corrective lens 1102M.

[0143] In addition, Fig.11 In the multifocal contact lens system 1100, Fig.13D The low-add DOF of one or more low-add hyperopia corrective lenses 1102H shown by their low-add hyperopia refractive power distributions 1302H-D is relative to Fig.13A One or more low-add myopia corrective lenses 1102M shown by their low-add myopia diopter distribution 1302M-A may vary from +0.10D to -0.10D. In another example, Fig.13E The middle lower light DOF of one or more middle lower light hyperopia corrective lenses 1102H shown by their middle lower light hyperopia refractive power distributions 1302H-E is relative to Fig. 13B One or more medium lower light myopia corrective lenses 1102M shown by their medium lower light myopia diopter distribution 1302M-B can change +0.05D to -0.25D. In another example, Fig.13F The high and low addition DOF of one or more high and low addition hyperopia corrective lenses 1102H shown by their high and low addition hyperopia refractive power distributions 1302H-F is relative to Fig. 13C One or more high and low addition myopia corrective lenses 1102M shown by their high and low addition myopia power distributions 1302M-C may vary from +0.15D to -0.15D.

[0144] As another example, Fig.13A As shown in the low-light-addition myopia refractive power distribution 1302M-A in the low-light-addition myopia correction lens 1102M, the first lower light-addition optical zone 1104M may have a lower light-addition optical zone radius (diameter D) between 0 mm and 0.23 mm. C1 The first transition optical zone 1106M(1) of the low-light-addition myopia correction lens 1102M may have a first optical axis A 1The radius of the first lower light addition optical zone 1104M is between 0.23 mm and 0.43 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.002D and +0.003D. The first transition optical zone 1106M(2) of the low lower light addition myopia correction lens 1102M may have a radius of between 0.23 mm and 0.43 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.002D and +0.003D. 1 The radius of the first lower light addition optical zone 1104M is between 0.44 mm and 0.67 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.002D and +0.003D. The first transition optical zone 1106M(2) of the low lower light addition myopia correction lens 1102M may have a radius of between 0.44 mm and 0.67 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.002D and +0.003D. 1 The radius is between 0.67 mm and 2.0 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.0005 D and +0.001 D. The low lower light addition myopia correction lens 1102M may have a farthest optical zone extrapolated paraxial diopter between +0.336 D and +0.537 D relative to the paraxial diopter of the refractive demand.

[0145] As another example, Fig. 13B As shown in the middle lower light addition myopia diopter distribution 1302M-B, the first lower light addition optical zone 1104M of the middle lower light addition myopia correction lens 1102M may have a lower light addition optical zone radius (diameter D) between 0 mm and 0.78 mm. C1 The first transition optical zone 1106M(1) of the medium lower light myopia correction lens 1102M may have a first optical axis A 1 The radius of the first lower light addition optical zone 1104M is between 0.78 mm and 1.06 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.343D and +0.425D. The first transition optical zone 1106M(2) of the medium lower light addition myopia correction lens 1102M may have a radius of 0.78 mm and 1.06 mm relative to the first optical axis A. 1 The radius of the first lower light addition optical zone 1104M is between 1.06 mm and 1.49 mm, wherein the first lower light addition diopter of the first lower light addition optical zone 1104M is between +0.262D and +0.344D.

[0166] Figure 25A-Figure 25C are exemplary graphs 2500A, 2500B, 2500B of the difference in central eye visual performance as a brightness difference for a high and low addition label diopter of +2.5D, which are plotted as Fig. 13C The function of the convergence (in units of focal power) between different refractive error correction prescriptions (Rx) of the high and low addition myopia correction lens 1102M represented by the corresponding high and low addition myopia refractive power distribution 1302M-C in FIG. 1 and with Figure 8A-8C In the graphs 800A-800C, the central eye visual performance of the high and low addition myopia corrective lens 402M corresponding to different refractive error correction prescriptions (Rx) is compared for the high and low addition label corresponding to +2.5D of light addition. Figure 25D-Figure 25F are exemplary graphs 2500D, 2500E, 2500F of the difference in central eye visual performance as a function of brightness difference for a +2.5D high and low addition label lower addition diopter, which are plotted as Fig.13F The function of the convergence (in units of focal power) between different refractive error correction prescriptions (Rx) of the high and low addition hyperopia corrective lens 1102H represented by the corresponding high and low addition hyperopia refractive power distributions 1302H-F in FIG. 1 and with Figure 8D-Figure 8FIn the graphs 800D-800F, the central eye visual performance of the high and low addition hyperopia corrective lens 402H corresponding to different refractive error correction prescriptions (Rx) is compared for the +2.5D corresponding high and low addition label light addition diopter.

[0167] like Figure 25D-Figure 25F As shown in the central eye visual performance curve 2500D-2500F, for the high and low light labels, the light addition diopter is Figure 4 Compared with the high and low addition hyperopia corrective lens 402H in the multifocal contact lens system 400, Fig.11 The high and low addition hyperopia correction lens 1102H in the multifocal contact lens system 1100 in FIG. 1 shows better distance vision performance. However, for the high and low addition label addition diopter, Figure 4 The high and low addition hyperopia correction lens 402H in the multifocal contact lens system 400 is more accurate at low light levels than Fig.11 The high and low addition hyperopia correction lens 1102H in the multifocal contact lens system 1100 in FIG. 1 shows better near vision. This is partly due to the Fig.11 The radius of the lower light-addition optical zone (diameter D) of the myopia correction lens 1102M in the multifocal contact lens system 1100 C1 half of Fig.11 The radius of the lower light addition optical zone (diameter D) of the hyperopia correction lens 1102H in the multifocal contact lens system 1100 C2 The reduced radius of the lower light-added optical zone (diameter D) of the hyperopia correction lens 1102H is C2 Half of the light) will result in less light being received in the pupil of the hyperope through the second lower light-adding optical zone 1104H when focusing at a near distance.

[0168] Fig.26 is an exemplary lens fitting guide 2600 that can be used to fit a patient with a lens from Fig.11 The myopia correction lens 1102M and / or hyperopia correction lens 1102H of the multifocal contact lens system 1100 are composed of Figures 13A-13F The myopia and hyperopia diopter distributions 1302M-A, 1302M-B, 1302M-C, 1302H-D, 1302H-E, 1302H-F in the lens fitting guide 2600 are shown. The "lens A" shown in the lens fitting guide 2600 represents a low-addition contact lens, which is composed of Fig.13A and Fig.13DThe low-add myopia correction lens 1102M and the hyperopia correction lens 1102H are represented by the low-add myopia and hyperopia refractive power distributions 1302M-A and 1302H-D in the lens fitting guide 2600. The "lens B" shown in the lens fitting guide 2600 represents a medium-addition contact lens. Fig. 13B and Fig.13E The medium lower light addition myopia correction lens 1102M and the hyperopia correction lens 1102H are represented by the respective medium lower light addition myopia and hyperopia refractive power distributions 1302M-B, 1302H-E in the lens fitting guide 2600. The "lens C" shown in the lens fitting guide 2600 represents a high lower light addition contact lens, which is composed of Fig. 13C and Fig.13F The high and low light addition myopia correction lens 1102M and the hyperopia correction lens 1102H are represented by the respective medium low light addition myopia and hyperopia refractive power distributions 1302M-C and 1302H-F.

[0169] It has also been found that not only do hyperopes generally have more corrected ocular SPHA than myopes, as previously discussed, but also that the ocular SPHA of hyperopes increases further as a function of increasing refractive error. Thus, in other exemplary aspects discussed below, Fig.11 The myopia and / or hyperopia power distribution of the myopia corrective lens 1102M and / or the hyperopia corrective lens 1102H in the multifocal contact lens system 1100 can be further refined to be dependent on the refractive error correction (i.e., dependent on the refractive error correction prescription or the refractive error correction label diopter) to further optimize the enhanced distance vision. The SPHA of the myopia corrective lens 1102M and / or the hyperopia corrective lens 1102H is dependent on the refractive error correction, which means that the SPHA further varies between different corresponding myopia and / or hyperopia error corrections within different corresponding myopia corrective lenses and / or hyperopia corrective lenses in the multifocal contact lens system. For example, the SPHA of the hyperopia corrective lens in the multifocal contact lens system can be designed to add more negative SPHA to the hyperopia corrective lens as the focal power of the hyperopia refractive error correction prescription of the hyperopia corrective lens increases. As another example, the SPHA of a myopia correction lens in a multifocal contact lens system can also be made dependent on the refractive error correction to enhance distance vision. For example, the SPHA in the myopia correction lens can be designed to add a more negative SPHA to the myopia correction lens as the power of the myopia refractive error correction prescription of the myopia correction lens increases (i.e., as the refractive error correction prescription becomes more and more negative).

[0170] At this point, Fig. 27A multifocal contact lens system 2700 is shown, which includes a myopia correcting multifocal lens 2702M (also referred to as "myopia correcting lens 2702M") and a hyperopia correcting multifocal lens 2702H (also referred to as "hyperopia correcting lens 2702H"). In this example, myopia correcting lens 2702M and hyperopia correcting lens 2702H are multifocal contact lenses. Each of myopia correcting lens 2702M and hyperopia correcting lens 2702H has an effective lower light addition power for correcting presbyopia specified with a given label lower light addition power. Note that although in Fig. 27 Only one (1) myopia corrective lens 2702M and one (1) hyperopia corrective lens 2702H are shown, but the multifocal contact lens system 2700 includes multiple myopia corrective lenses 2702M and multiple hyperopia corrective lenses 402H, each of the myopia corrective lenses having a different myopia refractive error correction indicated by a different myopia refractive error correction prescription (e.g., -1D, -2D, -3D, ..., -9D) and used for different label addition powers, and each of the hyperopia corrective lenses having a different hyperopia refractive error correction prescription (e.g., +1D, +2D, +3D, ..., +9D) and used for different label addition powers. In this way, one or more myopia corrective lenses 2702M and / or one or more hyperopia corrective lenses 2702H may be selected for the patient's OD and OS based on the refractive error in the patient's eyes to provide refractive error correction for corrective vision with multifocality and presbyopia correction.

[0171] As discussed in more detail below, the myopia corrective lens 2702M and / or the hyperopia corrective lens 2702H may also have a SPHA depending on their specific refractive error correction prescription. The myopia corrective lens 2702M and / or the hyperopia corrective lens 2702H may be similar to Fig.11 However, if the myopia correction lens 2702M in the multifocal contact lens system 2700 has a SPHA that is further dependent on its specific myopic refractive error correction prescription, then in this example, its myopia refractive power distribution will be different from Figure 13A-13C Similarly, if the hyperopic corrective lens 2702H in the multifocal contact lens system 2700 has a SPHA that is further dependent on its specific hyperopic refractive error correction prescription, then in this example, its hyperopic refractive power distribution will be different from Figure 13D-13F The hyperopia refractive power distribution in 1302H-D, 1302H-E, 1302H-F.

[0172] Moreover, it has been found that as the hyperopic refractive error increases, the pupil size of the hyperopic person decreases. Therefore, as discussed in more detail below, as an example, the second lower light-addition zone diameter D of the second lower light-addition optical zone 2704H of the hyperopic corrective lens 2702H is C4 It can be designed so that as the focal power of the hyperopia correction prescription of the hyperopia correction lens 2702H increases, the diameter D of the second lower light-adding optical zone 2704H increases. C4 The diameter D of the first lower light-addition zone of the first lower light-addition optical zone 2704M of the myopia correction lens 2702M in the multifocal contact lens system 2700 is reduced. C3 It can also be made dependent on the refractive error correction. For example, it has been found that the pupil size of a myopic person increases as the myopic refractive error increases (i.e., as the refractive error correction becomes more and more negative). Thus, as an example, the first lower light-addition zone diameter D of the first lower light-addition optical zone 2704M of the myopic corrective lens 2702M is C3 It can be designed so that as the focal power of the myopia correction prescription of the myopia correction lens 2740M decreases, the diameter D of the first lower light-adding optical zone 2704M increases. C3 Increase.

[0173] In this way, one or more myopia corrective lenses 2702M and / or one or more hyperopia corrective lenses 2702H can be selected from the multifocal contact lens system 2700 for the patient's OD and OS based on the refractive error in the patient's eye to provide further improved refractive error correction for corrective vision and improved longer distance vision for hyperopes with multifocality and presbyopia correction.

[0174] refer to Fig. 27 , the myopia correction lens 2702M and the hyperopia correction lens 2702H provide multifocality, wherein the near vision of presbyopia is corrected. The myopia correction lens 2702M has a myopia refractive power distribution provided by a first lower light-adding optical zone 2704M and a first transition optical zone 2706M(1)-2706M(3) surrounding the first lower light-adding optical zone 2704M. The myopia correction lens 2702M may also have a farthest distance optical zone 2706M(F) surrounding the first transition optical zone 2706M(3) having a refractive correction power for distance vision. As a non-limiting example, the myopia correction lens 2702M may have a myopia correction power distribution provided by a first lower light-adding optical zone 2704M and a first transition optical zone 2706M(1)-2706M(3) surrounding the first lower light-adding optical zone 2704M. Fig.11 The first lower light-adding optical zone 2704M surrounds the first optical axis A. 1A first lower light-addition zone diopter distribution is provided and has a myopia correction lens 2702M as part of the myopia diopter distribution, the myopia correction lens having a myopia paraxial diopter selected to significantly correct the wearer's myopia refractive error for distance vision (e.g., at 0.25D) according to the wearer's refractive error correction prescription, and having a first lower light-addition diopter for correcting presbyopia. The first lower light-addition optical zone 2704M has a first lower light-addition zone diameter D C3 , whose size is based on the expected pupil contraction caused by pupil miosis when the wearer focuses on a near object (e.g., at 2.5D) to enhance presbyopia correction. In this way, when the wearer focuses on a near object, more light enters the wearer's pupil from the first lower light addition optical zone 2704M having the first lower light addition diopter. The first lower light addition optical zone 2704M can be spherical or have some target spherical aberration that depends on the myopic near-axis diopter in the first lower light addition optical zone 2704M. In this example, there are three (3) first transition optical zones 2706M(1)-2706M(3). The first transition optical zones 2706M(1)-2706M(3) are arranged around the first optical axis A 1 Surrounding the first lower light-addition optical zone 2704M, and each including a corresponding myopia progressive diopter distribution as part of the overall myopia diopter distribution of the myopia corrective lens 2702M. The myopia diopter distribution includes the first lower light-addition zone diopter distribution, and the myopia progressive diopter distribution includes a first spherical aberration (SPHA) to provide correction of myopia refractive error correction.

[0175] The first transition optical zones 2706M(1)-2706M(3) in the myopia corrective lens 2702M provide refractive correction of light rays ("light") passing through the myopia corrective lens 2702M relative to the first optical axis A of the myopia corrective lens 2702M. 1 The outside of the center-first lower light-adding optical zone 2704M has different radii R M3 For example, each first transition optical zone 2706M(1)-2706M(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. Fig. 27 The transitions between adjacent first transition optical zones 2706M(1)-2706M(3) are shown as different optical zones for illustrative purposes only, but in this example, the diopter changes at these respective transitions are continuous or substantially continuous. Thus, the myopia corrective lens 2702M may have a single transition optical zone surrounding the first lower light-adding optical zone 2704M and having a continuous aspheric diopter distribution diopter. Note, however, Fig. 27The transition between any adjacent first transition optical zones 2706M(1)-2706M(3) shown may also be discontinuous. However, note that Fig. 27 The diopter change at the transition between any adjacent first transition optical zones 2706M(1)-2706M(3) shown may also be discontinuous. The myopia corrective lens 2702M has an overall diameter D M3 .

[0176] Likewise Fig. 27 As shown, the hyperopia correction lens 2702H has a hyperopia refractive power distribution provided by the second lower light-adding optical zone 2704H and the second transition optical zones 2706H(1)-2706H(3) surrounding the second lower light-adding optical zone 2704H. The hyperopia correction lens 2702H may also have a farthest distance optical zone 2706H(F) surrounding the second transition optical zone 2706H(3) having a refractive correction power for far vision. The second lower light-adding optical zone 2704H surrounds the second optical axis A. 2 A second lower light-addition zone diopter distribution is provided and has a second lower light-addition zone diopter distribution as part of a hyperopia diopter distribution of a hyperopia corrective lens 2702H, the hyperopia corrective lens having a hyperopia paraxial diopter selected to significantly correct the wearer's hyperopia refractive error for distance vision (e.g., at 0.25D) according to the wearer's refractive error correction prescription, and having a second lower light-addition diopter for correcting presbyopia. In this example, the second lower light-addition optical zone 2704H has a second lower light-addition zone diameter D C4 , which is smaller than the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 2704M of the myopia correction lens 2702M. C3 This is based on the expected reduced pupil size of a hyperopic wearer when the pupil constricts to miosis when the wearer focuses on a near object (e.g., at 2.5D) compared to a myopic wearer of the myopia corrective lens 2702M.

[0177] The second lower light-addition optical zone 2704H can be spherical or have some target spherical aberration, which depends on the hyperopic near-axis diopter in the second lower light-addition optical zone 2704H. In this example, there are three (3) second transition optical zones 2706H(1)-2706H(3). The second transition optical zones 2706H(1)-2706H(3) are arranged around the second optical axis A. 2 Surrounding the second lower light addition optical zone 2704H, and each including a corresponding hyperopic progressive diopter distribution as part of the overall hyperopic diopter distribution of the hyperopic corrective lens 2702H. The hyperopic diopter distribution includes the second lower light addition zone diopter distribution, and the hyperopic progressive diopter distribution includes a second SPHA to provide correction of hyperopic refractive error correction.

[0178] Continue to refer Fig. 27 The second transition optical zones 2706H(1)-2706H(3) in the hyperopia corrective lens 2702H provide refractive correction of light rays ("light") passing through the hyperopia corrective lens 2702H relative to the second optical axis A of the hyperopia corrective lens 2702H. 2 The outer portion of the second lower light-adding optical zone 2704H has different radii R H3 For example, each second transition optical zone 2706H(1)-2706H(3) may have a progressive power profile that provides the wearer with overall multifocality as a function of the distance of the focused object. Fig. 27 The transitions between adjacent second transition optical zones 2706H(1)-2706H(3) are shown as different optical zones for illustrative purposes only, but in this example, the diopter changes at these respective transitions are continuous or substantially continuous. Thus, the hyperopia corrective lens 2702H may have a single transition optical zone surrounding the second lower light-adding optical zone 2704H and having a continuous aspheric diopter distribution diopter. Note, however, Fig. 27 The transition between any adjacent second transition optical zones 2706H(1)-2706H(3) shown may also be discontinuous. However, note that Fig. 27 The diopter change at the transition between any adjacent second transition optical zones 2706H(1)-2706H(3) shown may also be discontinuous. The hyperopia corrective lens 2702H has an overall optical zone diameter D H3 .

[0179] Moreover, if Fig. 27 As shown, Fig.11 The multifocal contact lens system 1100 provided in the multifocal contact lens system 2700 has a myopia power distribution in each myopia corrective lens 2702M having a first SPHA 2712M that is larger than a second SPHA 2712H in each hyperopia power distribution of a hyperopia corrective lens 2702H in the multifocal contact lens system 2700. In other words, the second SPHA 2712H in the hyperopia power distribution of the hyperopia corrective lens 2702H is smaller than the first SPHA 2712M in the myopia power distribution of the myopia corrective lens 2702M. The first SPHA 2712M in the myopia corrective lens 2702M is a spherical aberration in the myopia power distribution of the myopia corrective lens 2702M, which is a function of their relative position to the first optical axis A. 1 The radius R M3 The second SPHA 2712H in the hyperopia corrective lens 2702H is a spherical aberration in the hyperopia refractive power distribution of the hyperopia corrective lens 2702H as a function of their relative to the second optical axis A. 2 The radius R H3As previously described, reducing the second SPHA 2712H in the hyperopia corrective lens 2702H in the multifocal contact lens system 2700 relative to the first SPHA 2712M in the myopia corrective lens 2702M in the multifocal contact lens system 2700 can further improve the distance vision of a hyperopic person wearing the hyperopia corrective lens 2702H in the multifocal contact lens system 2700.

[0180] Moreover, in Fig. 27 In the multifocal contact lens system 2700 in FIG. 2 , the second SPHA 2712H of each of the plurality of hyperopia corrective lenses 2702H depends on its hyperopia refractive error correction label diopter. In other words, in addition to the second SPHA 2712H in the hyperopia refractive power distribution of the hyperopia corrective lens 2702H being smaller than the first SPHA 2712M in the myopia refractive power distribution of the myopia corrective lens 2702M, the second SPHA 2712H in the hyperopia refractive power distribution of the hyperopia corrective lens 2702H also becomes more negative as the power of the hyperopia refractive error correction prescription increases. For example, in this example, the hyperopia corrective lens 2702H having a hyperopia refractive error correction prescription of +4D will have a second SPHA 2712H that is more negative than the second SPHA 2712H of the hyperopia corrective lens 2702H having a hyperopia refractive error correction prescription of +2D. In this way, Fig. 27 The hyperopic power distribution of the hyperopic corrective lens 2702H in the multifocal contact lens system 2700 may be further optimized to be dependent on the hyperopic refractive error correction to further optimize for even more enhanced distance vision.

[0181] In an example, the second SPHA 2712H of each of the plurality of presbyopic corrective lenses 2702H may be targeted to the average second eye SPHA of a population of presbyopes for their given presbyopic refractive error, such as Fig. 9BAs shown in the graph 900B in FIG. 900B . As another example, the second SPHA 2712H of the hyperopia corrective lens 2702H may be at least ten percent (10%) smaller than the first SPHA 2712M of the myopia corrective lens 2702M. As another example, for a given corresponding refractive error correction prescription (e.g., a +2D hyperopia refractive error correction prescription to a -2D myopia refractive error correction prescription), the second SPHA 2712H of the hyperopia corrective lens 2702H may be at least ten percent (10%) smaller than the first SPHA 2712M of the myopia corrective lens 2702M. As another example, the second SPHA 2712H of the hyperopia corrective lens 2702H in the multifocal contact lens system 2700 may be ten percent (10%) to twenty percent (20%) smaller than the first SPHA 2712M in the myopia corrective lens 2702M in the multifocal contact lens system 2700. As another example, the second SPHA 2712H of each of the plurality of presbyopia corrective lenses 2702H may be at -0.053D / mm. 2 and -0.146D / mm 2 and the first SPHA 2712M of each of the plurality of myopia corrective lenses 2702M may be between 0.053D / mm 2 and -0.146D / mm 2 between.

[0182] In another example, as the power of the hyperopic refractive error correction prescription of the plurality of hyperopic corrective lenses 2702H increases, the second SPHA 2712H of the plurality of hyperopic corrective lenses 2702H becomes more negative monotonically (i.e., in the same increment between adjacent hyperopic refractive error correction prescriptions). As the power of the hyperopic refractive error correction prescription of the plurality of hyperopic corrective lenses 2702H increases, the second SPHA 2712H of the plurality of hyperopic corrective lenses 2702H may become more negative linearly.

[0183] Moreover, in Fig. 27In the multifocal contact lens system 2700 of FIG. 27, the first SPHA 2712M of each of the plurality of myopia corrective lenses 2702M may also depend on its myopia refractive error correction label diopter. In other words, in addition to the first SPHA 2712M in the myopia refractive power distribution of the myopia corrective lens 2702M being larger than the second SPHA 2712H in the hyperopia refractive power distribution of the hyperopia corrective lens 2702H, the first SPHA 2712HM in the myopia refractive power distribution of the myopia corrective lens 2702M also becomes more negative as the focal power of the myopia refractive error correction prescription increases. For example, in this example, the myopia corrective lens 2702M having a myopia refractive error correction prescription of -4D will have a first SPHA 2712M that is more negative than the first SPHA 2712M of the myopia corrective lens 2702M having a myopia refractive error correction prescription of -2D. In this way, Fig. 27 The myopia power distribution of the myopia corrective lens 2702M in the multifocal contact lens system 2700 can be further optimized to be dependent on the myopia refractive error correction to further optimize for more enhanced distance vision.

[0184] In another example, the first SPHA 2712M of each of the plurality of myopia corrective lenses 2702M may be targeted to the average first eye SPHA of a myopic population for their given myopic refractive error, such as Fig. 9A As shown in the graph 900A in FIG. 1 . As another example, the second SPHA 2712H of the hyperopia corrective lens 2702H may be at least five percent (5%) smaller than the first SPHA 2712M of the myopia corrective lens 2702M. As another example, for a given corresponding refractive error correction prescription (e.g., a -2D myopia refractive error correction prescription to a +2D hyperopia refractive error correction prescription), the second SPHA 2712H of the hyperopia corrective lens 2702H may be at least five percent (5%) smaller than the first SPHA 2712M of the myopia corrective lens 2702M. As another example, the second SPHA 2712H of the hyperopia corrective lens 2702H may be three percent (3%) to fifty percent (50%) smaller than the first SPHA 2712M of the myopia corrective lens 2702M. In another example, the first SPHA 2712M of a plurality of myopia corrective lenses 2702M having only a myopia correction prescription of -2.5D or greater becomes more negative as the power of the myopia correction prescription of such myopia corrective lenses 2702M increases, thereby reducing or counteracting the eye SPHA to further improve longer distance vision. As an example, the first SPHA 2712M of each of the plurality of myopia corrective lenses 2702M may be -0.053D / mm 2 and -0.146D / mm2 and the first SPHA 2712M of each of the plurality of myopia corrective lenses 2702M may be between -0.064D / mm 2 and -0.096D / mm 2 between.

[0185] In another example, as the power of the myopia correction prescription of the plurality of myopia correction lenses 2702M increases, the first SPHA 2712M of the plurality of myopia correction lenses 2702M becomes more negative monotonically (i.e., in the same increments between adjacent myopia correction prescriptions). As the power of the hyperopia correction prescription of the plurality of hyperopia correction lenses 2702H increases, the first SPHA 2712M of the plurality of myopia correction lenses 2702M may become more negative linearly.

[0186] As described above, the second lower light-adding optical zone 2704H of the hyperopia correction lens 2702H also has a second lower light-adding zone diameter D C4 , which is smaller than the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 2704M of the myopia correction lens 2702M. C3 This is based on the expected reduced pupil size of the hyperopic wearer when the pupil constricts to miosis when the wearer focuses on a near object (e.g., at 2.5D). In this way, when the hyperopic wearer focuses on a distant object, a greater percentage of light enters the pupil of the hyperopic wearer from the second transition optical zone 2706H(1)-2706H(3) of the hyperopic corrective lens 2702H to provide improved vision at longer distances. As an example, the second lower light-addition zone diameter D of the second lower light-addition optical zone 2704H of the hyperopic corrective lens 2702H is C4 The diameter D of the first lower light area of ​​the comparable myopia correction lens 2702M C3 At least two percent (2%) smaller.

[0187] Furthermore, as mentioned above, it has been found that as the hyperopic refractive error increases, the pupil size of the hyperopic person becomes smaller. This has been previously shown for a patient with a +2.0D refractive error correction prescription (Rx) and a +2.25D add diopter requirement and 120 cd / m 2 Example description of the brightness and 2D vergence of an average hyperopic subject Fig. 10B For example, based on the average pupil diameter observed in hyperopes, the diameter D of the second lower light-adding optical zone 2704H of the hyperopic corrective lens 2702H is C4 It can be between 0mm and 0.73mm. Fig. 27In this example of the multifocal contact lens system 2700, the second lower light-addition zone diameter D of the second lower light-addition optical zone 2704H of the hyperopia correction lens 2702H in the multifocal contact lens system 2700 is C4 It can also be made to depend on the correction of hyperopia refractive error to further improve the distance vision performance. For example, the second lower light-adding area diameter D of the second lower light-adding optical area 2704H of the hyperopia correction lens 2702H is C4 It can be designed so that as the focal power of the hyperopia correction prescription of the hyperopia correction lens 2702H increases, the diameter D of the second lower light-adding optical zone 2704H increases. C4 For example, the diameter D of the second lower light-adding area of ​​the second lower light-adding optical zone 2704H of the plurality of hyperopia correction lenses 2702H is C4 It can be designed to continuously reduce in size as the power of the hyperopic refractive error correction prescription of the multiple hyperopic corrective lenses 2702H increases. For example, the second lower light-adding zone diameter D of the second lower light-adding optical zone 2704H of the hyperopic corrective lens 2702H with a +2D hyperopic refractive error correction prescription C4 The second lower light-addition zone diameter D of the second lower light-addition optical zone 2704H of the hyperopia correction lens 2702H having a +4D hyperopia refractive error correction prescription is C4 Larger diameter.

[0188] As another example, as the focal power of the hyperopic refractive error correction prescription of the plurality of hyperopic corrective lenses 2702H increases, the diameter D of the second lower light addition zone of the plurality of hyperopic corrective lenses 2702H increases. C4 The diameter D of the second lower light-addition zone of the plurality of hyperopia corrective lenses 2702H may continue to decrease monotonically (i.e., decrease in increments at the same distance between adjacent hyperopia refractive error correction prescriptions). For example, in another example, as the focal power of the hyperopia refractive error correction prescription of the plurality of hyperopia corrective lenses 2702H increases, the diameter D of the second lower light-addition zone of the plurality of hyperopia corrective lenses 2702H decreases. C4 It can continue to decrease linearly.

[0189] In another example, the first lower light-adding optical zone 2704M of the myopia correction lens 2702M further has a first lower light-adding zone diameter D C3 , which is larger than the diameter D of the second lower light-adding area of ​​the second lower light-adding optical area 2704H of the hyperopia correction lens 2702H. C4 Therefore, in Fig. 27 In this example of the multifocal contact lens system 2700, the first lower light-addition zone diameter D of the first lower light-addition optical zone 2704M of the myopia correction lens 2702M in the multifocal contact lens system 2700 is C3It can also be made to depend on the correction of myopia refractive error to further improve the distance vision performance. For example, the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 2704M of the myopia correction lens 2702M is C3 It can be designed so that as the focal power of the myopia correction prescription of the myopia correction lens 2702M increases, the diameter D of the first lower light-adding optical zone 2704M increases. C3 For example, the diameter D of the first lower light-adding area of ​​the first lower light-adding optical zone 2704M of the plurality of myopia correction lenses 2702M is C3 The diameter D of the first lower light-adding optical zone 2704M of the myopia correction lens 2702M with a -4D hyperopia correction prescription is continuously increased as the focal power of the myopia correction lens 2702M increases. C3 The first lower light-addition zone diameter D of the first lower light-addition zone 2704M of the myopia correction lens 2702M having a myopia refractive error correction prescription of -2D is C3 Larger diameter.

[0190] As another example, as the focal power of the hyperopic refractive error correction prescription of the plurality of hyperopic corrective lenses 2702H increases, the diameter D of the second lower light addition zone of the plurality of hyperopic corrective lenses 2702H increases. C4 The diameter D of the second lower light-addition zone of the plurality of hyperopia corrective lenses 2702H may continue to decrease monotonically (i.e., decrease in increments at the same distance between adjacent hyperopia refractive error correction prescriptions). For example, in another example, as the focal power of the hyperopia refractive error correction prescription of the plurality of hyperopia corrective lenses 2702H increases, the diameter D of the second lower light-addition zone of the plurality of hyperopia corrective lenses 2702H decreases. C4 It can continue to decrease linearly.

[0191] In addition, as described above, it has been found that, in general, myopes and hyperopes differ in the distribution of lower add diopter needs. A higher proportion of hyperopes are fitted with high lower add diopter lenses compared to myopes of the same or similar age. Therefore, hyperopes with higher lower add diopter may experience greater distance vision impairment compared to myopes. Moreover, as described above, hyperopes may already have a natural tendency to feel that their distance vision is impaired when fitted with presbyopia correction lenses due to their expected superior distance vision than myopes. Therefore, in another example, in order to improve the distance vision of a hyperope, for a given labeled lower add diopter, the effective lower add diopter in the hyperopia correction lens 2702H in the multifocal contact lens system 2700 may also be reduced compared to the effective lower add diopter in the myopia correction lens 2702M in the multifocal contact lens system 2700. Moreover, utilizing the binocular disparity between the dominant and non-dominant eyes of the patient, it may be desirable to reduce the effective lower add diopter within only certain effective label lower add diopter ranges of the hyperopia correcting multifocal lens 2702H to improve distance vision. For example, for a given label lower add diopter, the effective lower add diopter in some or all of the hyperopia correcting lenses 2702H may be reduced by +0.0D to +0.65D compared to the label lower add diopter of the myopia correcting lens 2702M. The effective lower add diopter in the hyperopia correcting lens 2702H in the multifocal contact lens system 2700 may be provided by adjusting its paraxial diopter and the aspheric constant in its corresponding hyperopia diopter profile.

[0192] Moreover, for a given label addition power, the DOF of one or more hyperopia corrective lenses 2702H may be changed relative to the DOF of one or more myopia corrective lenses 2702M for the same given label addition power.

Note, however, that the high and low add label lower add diopter can be between +2.0D and +2.5D.

This is because in this example, the low lower add, medium lower add, and high lower add myopic diopter distributions 2802M-A, 2802M-B, 2802M-C of the corresponding low lower add, medium lower add, and high lower add myopic corrective lenses 2702M do not have the first SPHA 2712M or the first lower add area diameter R depending on their myopic refractive error correction prescriptions.

[0196] In this example, the hyperopia corrective lens 2702H Figure 28D-Figure 28F The hyperopic power distribution 2802H-D, 2802H-E, 2802H-F of the second SPHA 2712H depends on its refractive error correction prescription. For example, if Fig.28D As shown in the low-add hyperopia refractive power distribution 2802H-D in the figure, the low-add hyperopia corrective lens 2702H shown in the figure may have a second SPHA 2712H, which is a radius R H3 Function of D / mm 2 =Rx=0.003972*Rx-0.1118, where Rx is in units of focal length.

[0198] As described above, the effective lower added diopter (e.g., paraxial diopter) of the hyperopia corrective lens 2702H can be reduced relative to the effective lower added diopter (e.g., paraxial diopter) of the myopia corrective lens 2702M to further improve the distance vision of the hyperopic person wearing the hyperopia corrective lens 2702H.
