[0001] This application is a divisional application of the invention patent application filed on September 23, 2020, with application number 202080067295.8 (PCT / AU2020 / 051005) entitled "Apparatus and Method for a Solution for Myopia Eyeglasses". Cross-Reference to Related Applications

[0002] This application claims priority to Australian Provisional Application No. 2019 / 903581, filed on September 25, 2019, entitled "A spectacle lens set for myopia", and another Australian Provisional Application No. 2020 / 900413, filed on February 14, 2020, entitled "Lens kit", both of which are incorporated herein by reference in their entirety.

[0003] This disclosure relates to apparatus for managing eye length disorders, such as myopia. The invention includes apparatus and methods for prescribing, selecting, supplying, and fitting sets, stocks, or kits of paired myopia management glasses or eyeglass front components, wherein the apparatus and methods are configured to provide generally toric or astigmatic or asymmetrical optical directional cues to slow, improve, control, inhibit, or reduce the rate of myopia progression over time, wherein the method is a prescribed care protocol that provides temporal and spatial variations for the directional cues or optical stop signals.

[0004] The present invention also includes apparatus and methods for prescribing, selecting, supplying, and fitting assemblies, stockpiles, or kits of attachable, non-permanent auxiliary optical films or elements for use in conjunction with standard monocular glasses for correcting refractive errors in an individual, wherein the apparatus and methods are configured to provide generally toric or astigmatic or asymmetric directional cues to slow, improve, control, inhibit, or reduce the rate of myopia progression over time, wherein the method isA prescribed care protocol that provides temporal and spatial variations for directional cues or optical stop signals. Background Art

[0005] The human eye is farsighted at birth, where the length of the eyeball is too short for the total optical power of the eye. As a person grows from childhood to adulthood, the eyeball continues to grow until the refractive state of the eye stabilizes.

[0006] Eye growth is controlled by feedback mechanisms and primarily regulated by visual experience of the world to match the eye's optics with its length and maintain homeostasis. This process is called emmetropization.

[0007] The signal that guides the emmetropization process is initiated by adjusting the light energy received at the retina. Retinal image features are monitored by biological processes that adjust the signal to start or stop, accelerate or slow eye growth. This process coordinates between optics and eyeball length to achieve or maintain emmetropia. Derailment from this emmetropization process can potentially lead to refractive disorders, such as myopia. It is assumed that increased retinal activity inhibits eye growth, and vice versa.

[0008] In many parts of the world, the incidence of myopia is increasing at an alarming rate. In myopic individuals, the axial length of the eye is mismatched with the overall focal power of the eye, causing distant objects to focus in front of the retina.

[0009] A simple pair of negative single-vision lenses can correct myopia. While such devices can optically correct refractive errors associated with eye length, they do not address the underlying cause of excessive eye growth in the progression of myopia. Specification 1 / 30 pages 9 CN 121254519 A

[0010] Excessive eye growth in high myopia is associated with significant vision-threatening conditions such as cataracts, glaucoma, myopic macular degeneration, and retinal detachment. Therefore, there remains a need for specific optical devices for these individuals that not only correct underlying refractive errors but also largely prevent excessive eye elongation over time.

[0011] To date, many spectacle lens designs have been proposed to control the rate of myopia progression. Existing technologies include the use of executive D-shaped and concentric bifocal glasses, symmetrical and asymmetrical progressively added lenses, simultaneous defocusing regions on the lens, and glasses with positive spherical aberration, also known as peripheral lenses. In other words, all designs have a certain degree of additional power related to the prescription power of the lens, which is distributed symmetrically or asymmetrically in rotation along the optical axis of the glasses.

[0012] Each of these options has its advantages and disadvantages regarding slowing the rate of myopia progression in an individual. Some of the disadvantages are described herein.

[0013] For example, some problems with existing eyeglass designs—which are based on various types of bifocal lenses or peripheral powers—introduce noticeable visual impairments such as wobbling effects, image jitter, residual aberration, and peripheral distortion.This can impair visual quality at various other angles of view.

[0014] These side effects are primarily attributed to multiple defocused areas, significant levels of multiple defocused areas or segments, the use of a large amount of positive spherical aberration in the lens, or a significant change in power within a given area of ​​the spectacle lens. Given the impact of compliance with spectacle lens wearing on the efficacy of these lenses, a significant reduction in visual performance can promote poor compliance, leading to poorer efficacy of these lenses.

[0015] Therefore, there is a need for spectacle designs for correcting myopia and slowing its progression without causing at least one or more of the disadvantages discussed herein.

[0016] Furthermore, some prior art may not be aesthetically appealing to children, adolescents, and young adults, such as those that form the dividing line for D-shaped bifocal glasses, implementation bifocal glasses, etc. As discussed herein, other solutions will become apparent.

[0017] It appears that the methods disclosed in the prior art for addressing myopia progression may not meet an individual's need for lenses that provide an effective myopia control solution in one or more ways while being effectively used in their daily life. Therefore, systems involving kits and sets for solving the problems disclosed herein, as well as methods for specifying kits and sets, become desirable.

[0018] One of the disadvantages of prior art myopia management glasses is their associated high accessibility cost, which sets the barrier to entry too high for the average person who needs the solution. Therefore, there is a need for devices and / or methods that provide a budget-friendly solution to myopia problems, which can improve the accessibility of the solution for the population in need.

Detailed Description

[0092] The efficacy of prior art eyeglass designs has been established through randomized controlled clinical trials. The duration of these trials, including eyeglass designs, ranges from six months to three years, and the reported efficacy ranges from 10% to 50% compared to single-vision control lenses.

[0093] A simple emmetropic linear model shows that the magnitude of the stop signal accumulates over time. In other words, the accumulated stop signal depends on the total amplitude of the exposure rather than its temporal distribution.

[0094] A striking observation in all clinical trials is that almost all slowing effects on the rate of progression occur as an initial burst of treatment effect observed in the first 6 to 12 months and appear to gradually diminish over time. Therefore, a more reliable emmetropization model consistent with clinical results suggests that there may be a delay before the establishment of a stopping signal, followed by saturation over time, and potentially attenuation in the effectiveness of the stopping signal.

[0095] There is a need in the art for spectacle lenses that avoid or minimize this saturation effect by providing a stopping signal that varies temporally and spatially, for example, by means of a prescribed care regimen, which requires the use of paired myopia-managed eyes from a group or kit for a prescribed period of time.Switching of spectacle lenses, or switching of the front portion or non-permanent auxiliary optical film, sheet, or micro-optical element of a pair of myopia management lenses used in conjunction with a standard single-vision lens. In addition to spectacle lens pairs from a set or kit specified according to a care protocol, this disclosure also describes the use of the front portion and / or non-permanent optical film and micro-optical element of a set or kit used in conjunction with a pair of standard spectacle lenses specified according to a care protocol.

[0096] Therefore, there is a need for optical interventions having mechanisms that achieve significantly greater and / or substantially consistent efficacy in reducing and / or slowing myopia progression over time without significantly impairing visual performance. In one or more examples, substantially consistent efficacy over time can be considered to be at least 6 months, 12 months, 18 months, 24 months, 36 months, 48 ​​months, or 60 months.

[0097] In this section, this disclosure will be described in detail with reference to one or more embodiments, some of which are illustrated and supported by accompanying drawings. Examples and embodiments are provided by way of explanation and should not be construed as limiting the scope of this disclosure. The following description is provided with respect to several embodiments that may share common features and characteristics of this disclosure. It should be understood that one or more features of one embodiment may be combined with one or more features of any other embodiment that may constitute an additional embodiment. The functional and structural information disclosed herein should not be construed as limiting in any way, but should be construed merely as an illustrative basis for teaching those skilled in the art to adopt the disclosed embodiments and variations thereof in various ways. Subheadings and related subject headings included in the detailed description section are for the convenience of the reader only and should in no way be used to limit the subject matter found throughout the invention or claims of this disclosure.

[0098] The risk of developing or progressive myopia can be based on one or more of the following factors: genetics, race, lifestyle, environment, excessive close work, etc. Certain embodiments of this disclosure are aimed at people at risk of developing or progressive myopia. Specification 10 / 30 pages 18 CN 121254519 A

[0099] One or more advantages are found in one or more of the disclosed optical devices and methods of myopia management kits. A set or set of paired myopia management lenses or anterior components, non-permanent auxiliary optical films, sheets, or micro-optical elements, or methods used with standard single-vision lenses, provide a stop signal to delay the rate of eye growth or to stop the growth (or refractive error) of the wearer's eye based on an astigmatic blur signal.

[0100] A set or set of paired myopia management lenses or anterior components used with standard single-vision lensesComponents, non-permanent auxiliary optical films, sheets, or micro-optical elements or methods provide stop signals that vary in time and space to improve the effectiveness of managing progressive myopia. The present invention envisions devices and / or methods not based on positive spherical aberration or simultaneous defocus, which suffer from a saturation effect on therapeutic efficacy due to the rotational symmetry of the optical stop signal.

[0101] Figure 1 illustrates an uncorrected -3D myopia model eye 100. When an incoming ray (e.g., 101) of a visible wavelength (e.g., 589 nm) with a convergence-divergence ratio of 0 D is incident on the uncorrected myopic eye, the resulting image on the retina has a symmetrical blur 102 caused by defocus. This schematic diagram illustrates an on-axis geometric spot analysis at the retinal plane.

[0102] Figure 2 illustrates a schematic diagram of an on-axis geometric spot analysis at the retinal plane when the -3D myopia model eye 200 of Figure 1 is corrected with a standard monocular lens of the prior art or a commercially available monocular lens 202. Here, in this example, when an incoming ray (e.g., 201) of a visible wavelength (e.g., 589 nm) with a convergence-divergence ratio of 0 D is incident on the corrected myopic eye, the resulting image on the retina has a symmetrical sharp focus 203.

[0103] Figure 3 shows a schematic diagram of the on-axis through-focus geometric spot analysis at the retinal plane when the -3D myopic model eye 300 of Figure 1 is corrected using one of the exemplary embodiments 302 disclosed herein. Here, in this example, when an incoming ray (e.g., 301) of a visible wavelength (e.g., 589 nm) with a convergence-divergence ratio of 0 D is incident on the corrected myopic eye 300, the resulting defocused image on the retina forms a Sturm cone or interval having a minimum blur circle between 303a and 303b and elliptical blur patterns 303a and 303b having a sagittal plane and a tangential plane. Some example implementations involve a method of modifying incoming light by providing an astigmatic cue (i.e., a stop signal) at the retina of the eye using a spectacle lens system. This can be achieved, in addition to a standard prescription for correcting myopia, by using an astigmatic prescription or a torus prescription. In short, an additional astigmatic prescription or torus prescription can be used to reduce the rate of myopia progression by introducing an astigmatic cue (i.e., a stop signal) at the retinal level. In some implementations, the use of astigmatic cues obtained using a myopia management kit can be configured to provide a stop signal that varies temporally and spatially.

[0104] Schematic model eyes (Table 1) are selected in Figures 1 through 3 for illustrative purposes. However, in other implementations, schematic ray-tracing model eyes such as Liou-Brennan, Escudero-Navarro, etc., can be used instead.A simple model eye is provided. An illustrative model eye can also vary parameters of the cornea, lens, retina, ocular media, or combinations thereof to further aid in simulating the embodiments disclosed herein. The embodiments provided herein have used a -3D myopic model eye to disclose the invention; however, the same disclosure can be extended to other degrees of myopia, such as -1D, -2D, -5D, or -6D. Furthermore, it is understood that the scope of the invention can be extended to eyes with varying degrees of myopic refractive errors, with or without astigmatism.

[0105] In the example embodiment, a specific wavelength of 598 nm is referenced; however, it is understood that those skilled in the art can extend this to other visible wavelengths between 420 nm and 760 nm. The specific structural and functional details disclosed in these figures and examples should not be construed as limiting, but merely as an illustrative basis for teaching those skilled in the art to employ the disclosed embodiments in various variations.

[0106] Certain embodiments of this disclosure relate to a myopia management kit or set that can provide progressive myopic eyes with a stop signal that varies temporally and spatially—in other words, changes over time with retinal positioning (see manual page 11 / 30, 19 CN 121254519 A)—achieved with the aid of a prescribed wearing protocol. This temporally and spatially varying stop signal can minimize the inherent saturation effect of therapeutic efficacy observed in the prior art.

[0107] In some embodiments, when used in conjunction with a standard single-vision lens, the torus portion of the myopia management lens or the anterior part of the lens provides at least partially meridional correction for myopic eyes and at least partially generates a temporally and spatially varying astigmatism stop signal to reduce the rate of myopia progression when worn according to a care protocol. In some embodiments, the astigmatism initiation (i.e., stop signal) configured in the front portion of a pair of myopia management lenses or spectacle lenses used in conjunction with a standard single-vision lens in a kit or set can be at least +0.5 DC, +0.75 DC, +1 DC, or +1.25 DC. In some embodiments, the astigmatism initiation configured in the front portion of a pair of myopia management lenses or spectacle lenses used in conjunction with a standard single-vision lens in a kit or set can be between +0.5 DC and +1.75 DC, between +0.5 DC and +2 DC, or between +0.5 DC and +2.5 DC.

[0108] FIG4 illustrates a flowchart of an exemplary method for specifying a myopia management lens kit or set according to an exemplary aspect of the present disclosure to reduce, suppress, or control the rate of myopia progression in an individual.

[0109] In this example, the optimal objective or subjective refraction for each eye of the individual is identified.The basic prescription for the left and right eyes 401.

[0110] An astigmatic power distribution or torus power distribution of appropriate size and axis is selected and combined with the basic prescription for at least two pairs of myopia management glasses for an individual 402.

[0111] The at least two pairs of myopia management glasses are configured to at least partially provide meridional correction for the eye and at least partially provide meridional astigmatic blurring as a light signal for the eye 403.

[0112] Furthermore, the method of use of the at least two pairs of myopia management glasses lenses specified under the care program provides the eye with a stop signal that varies spatially and temporally 404.

[0113] In some examples, the appropriate level of astigmatism configured in the pairs of myopia management glasses lenses used in combination with standard monocular lenses in a kit or set may be at least +0.5 DC, +0.75 DC, +1 DC, +1.25 DC, or +1.75 DC.

[0114] In some examples, the appropriate level of astigmatism configured in a pair of myopia management lenses used in conjunction with a standard single-vision lens in a kit or set may be between +0.5 DC and +1.75 DC, between +0.5 DC and +2 DC, or between +0.5 DC and +2.25 DC.

[0115] In some examples, the appropriate difference in the axial orientation of the individual lenses of the pair of myopia management lenses may be at least 15 degrees, 30 degrees, 45 degrees, 60 degrees, or 75 degrees.

[0116] In some examples, the appropriate difference in the axial orientation of the individual lenses of the pair of myopia management lenses may be between 15 degrees and 30 degrees, between 30 degrees and 60 degrees, between 45 degrees and 75 degrees, between 60 degrees and 90 degrees, or between 15 degrees and 90 degrees.

[0117] To demonstrate the effects of other embodiments, other illustrative model eyes such as Atchison, Escudero-Navarro, Liou-Brennan, Polans, and Goncharov-Dainty can be used instead of the aforementioned illustrative model eyes.

[0118] One embodiment may also change the parameters in the various parameters of the model eye; for example, the cornea, lens, retina, media, or combinations thereof are described to help better simulate the effects. The illustrative eye is used to simulate the optical performance results of the exemplary embodiments of this disclosure.

[0119] The prescribed parameters of the illustrative model eye used for optical modeling and performance simulation are listed in Table 1.

[0120] This formulation provides a -3D myopic eye defined for a monochromatic wavelength of 589 nm. The formulation description 12 / 30 pages 20 CN 121254519 A described in Table 1 should not be construed as a necessary method for demonstrating the effects of the intended exemplary embodiments. This formulation is merely one of many methods that can be used by those skilled in the art for optical simulation purposes.Table 1: Schematic model eye prescriptions for -3D myopia model eyes are provided.

[0121] Table 2 provides myopia management eyeglass lenses with prescriptions of -3D / +1 DC. The prescriptions for the two pairs of exemplary myopia management eyeglass lens embodiments 501 and 510 illustrated in FIG5 are: first pair: -3D / +1 DC x 90 (right and left eyes); second pair: -3D / +1 DC x 135 (right eye) and second pair: -3D / +1 DC x 45 (left eye). Table 2: Prescriptions for exemplary eyeglass lens embodiments of the present disclosure.

[0122] FIG5 illustrates two pairs of exemplary myopia management eyeglass lenses 501 and 510 prescribed according to the present disclosure for reducing, inhibiting or controlling the rate of myopia progression in an individual.

[0123] The astigmatic blur (i.e., stop signal) of 1 DC is combined with the basic prescription for each eye. The axis orientation for astigmatism blurring specified in the first pair is 90 degrees; the axis orientation for astigmatism blurring specified in the second pair is 135 degrees and 45 degrees for the wearer's right and left eyes, respectively. The first pair of myopia management glasses 501 is specified for use in the first time period, and the second pair of myopia management glasses 510 is specified for use in the second time period. The astigmatism prescription or torus prescription of the paired myopia management glasses in FIG5 is represented in the form of a cross cylindrical symbol using two principal meridians, with solid lines 502, 512 representing principal meridians with weaker positive focal length, and dashed lines 504, 514 representing principal meridians with stronger positive focal length.

[0124] In some examples, the two (2) wearing periods described in the method of use of the two pairs of myopia management glasses shown in FIG5 may be every other day of the week, such as Monday, Wednesday, and Friday. In some other examples, the two wearing periods may be specific days of the week; and in some other examples, the two (2) wearing periods may include specific days of the month. Instruction manual, pages 13 / 30, 21 CN 121254519 A

[0125] Figure 6 illustrates the point spread functions, which vary temporally and spatially on the axis at the retinal plane, for the first and second pairs of myopia management glasses (Table 1) when incoming light of a visible wavelength (e.g., 589 nm) with a convergence-divergence ratio of 0 D is incident on a myopic eye being corrected using the two pairs of exemplary myopia management glasses 501 and 502 of Figure 5.

[0126] When the pairs of myopia management glasses lenses described in Figure 5 are used according to the prescribed care protocol disclosed herein, the two rows of point spread functions 600 and 601 represent the temporally and spatially varying light signals on the axis to the wearer's retina. It can be seen that the first pair of myopia management glasses 501 provides astigmatic blurring in the vertical meridians 602 and 604 of the wearer's retina; while the second pair 502 provides astigmatic blurring in the oblique meridians 612 and 614.

[0127] Figure 7 illustrates the temporal and spatial variation of the signal when incoming light is incident on the right -3D myopia model eye, which is depicted as a wide-angle defocus spot diagram. The right -3D myopia model eye is corrected using two (2) pairs of myopia management glasses lenses as described in Figure 5 during two (2) specified time periods under a specified care protocol. The rows represent optical performance at various field of view angles: -10 degrees, 0 degrees, and 10 degrees.

[0128] The defocus spot diagram of Figure 7 is a representation of the time integral of the light signal obtained by integrating the resulting response when the right lens of the four pairs of glasses front components is fitted on the -3D myopia model eye. Time integration means combining the effects of the pairs of myopia management glasses worn during the specified two (2) time periods in a single defocus spot diagram representation.

[0129] Figure 8 illustrates the retinal signal when incoming light with a visible wavelength (589 nm) and a convergence of 0 D is incident on the right-3D myopia model eye of Table 1, which is corrected using the two pairs of spectacle lenses described herein. The retinal signal is depicted as the on-axis defocus modulus of the optical transfer function for the principal meridian and perpendicular meridian of the time-varying point spread function. The defocus optical transfer function of Figure 8 represents the time integral of the light signal obtained by integrating the resulting response when the right lens of the two (2) pairs of myopia management spectacle lenses is fitted on the right-3D myopia model eye. The time integral means combining the effects of the pairs of myopia management spectacle lenses worn over a specified two (2) time periods in a defocus spot diagram representation.

[0130] Figure 9 illustrates a sample of sixteen (16) non-exhaustive astigmatism prescriptions or torus prescriptions contemplated in this invention disclosure. The torus prescription in Figure 9 is represented by intersecting cylindrical symbols with two principal meridians, solid lines representing principal meridians with weaker positive focal length and dashed lines representing principal meridians with stronger positive focal length. The sixteen samples should not be construed as limiting the scope of the invention.

[0131] Figure 10 illustrates a set of four exemplary pairs of auxiliary spectacle front components 1000, 1010, 1020, and 1030, as disclosed herein, used alongside a pair of standard single-vision lenses to reduce, suppress, or control the rate of myopia progression in an individual.

[0132] The auxiliary spectacle front components of Figure 10 are configured to have astigmatism magnitudes of +1 DC to +2.5 DC and different cylindrical axis orientations in each eye. The astigmatic prescription or torus prescription of the paired anterior lens components in Figure 10 is represented by intersecting cylindrical symbols using two principal meridians. The solid lines 1002, 1012, 1022, and 1032 represent principal meridians with weaker positive focal power, and the dashed lines 1004, 1014, 1024, and 1034 represent principal meridians with stronger positive focal power for the right lens of the four exemplary auxiliary anterior lens components.

[0133] For example, in the right lens of the front part of the eyeglasses, the cylindrical axis orientations in the 1st, 2nd, 3rd, and 4th pairs of front parts are 0 degrees, 30 degrees, 60 degrees, and 90 degrees, respectively. In the left lens of the front part of the eyeglasses, the cylindrical axis focal powers in the 1st, 2nd, 3rd, and 4th pairs of front parts are 180 degrees, 150 degrees, 120 degrees, and 90 degrees, respectively. It is stipulated that the four pairs of auxiliary front parts 1000, 1010, 1020, and 1030 are used at different times. For example, each pair of auxiliary front parts may be replaced daily, every two days, every three days, every four days, every five days, every seven days, every ten days, every fourteen days, or every twenty-one days.

[0134] Figure 11 illustrates in detail the focal length diagram of a set of four pairs of exemplary auxiliary spectacle front parts 1000, 1010, 1020, 1030, as disclosed herein, used alongside a pair of standard spectacle lenses to reduce, suppress, or control the rate of myopia progression in an individual. The prescription for the right eye of the four pairs of exemplary spectacle front parts 1000, 1010, 1020, 1030 illustrated in Figure 10 is as follows: Pair 1: plano / +1.5 DC x 180 (right, 1101); Pair 2: plano / +1 DC x 120 (right, 1103); Pair 3: plano / +2.5 DC x 150 (right, 1105); and Pair 4: plano / +2 DC x 90 (right, 1107). The prescription for the left eye of the four pairs of exemplary eyeglass front components 1000, 1010, 1020, 1030 illustrated in Figure 10 is as follows: Pair 1: plano / +1.5 DC x 180 (left, 1102); Pair 2: plano / +1 DC x 60 (right eye, 1104); Pair 3: plano / +2.5 DC x 30 (right eye, 1106); and Pair 4: plano / +2 DC x 90 (right eye, 1108).

[0135] When a set of four (4) pairs of eyeglass front components 1000, 1010, 1020, 1030 described in Figure 10 are used in parallel with a standard single-vision lens for correcting myopia with or without astigmatism, the resulting temporally and spatially varying light signals obtained by integrating the responses over four predetermined time periods are illustrated in Figure 12. When an incoming ray having a visible wavelength (589 nm) and 0 D convergence is incident on a -3D myopia model eye undergoing correction under a prescribed care regimen using the four pairs of auxiliary eyeglass front components 1000, 1010, 1020, and 1030 described in Figure 10, the on-axis retinal point spread functions depicted for the right eye 1201, 1203, 1205, and 1207 and the left eye 1202, 1204, 1206, and 1208 are calculated.

[0136] Figure 13 illustrates the temporal and spatial variations of the signal depicted as a wide-angle defocus spot diagram when incoming light is incident on the right -3D myopia model eye, which is corrected using the four (4) lenses of the eyeglasses described in Figure 10 over a prescribed care regimen for four (4) time periods. The rows represent optical performance at various field of view angles: -10 degrees, 0 degrees, and 10 degrees.

[0137] The defocus spot diagram of Figure 13 is a representation of the time integral of the light signal obtained by integrating the resulting response when the right lenses of the four pairs of eyeglasses are fitted on the -3D myopia model eye. The time integral means combining the effects of the pairs of myopia management glasses worn over the prescribed four (4) time periods in a single defocus spot diagram representation.

[0138] FIG14 illustrates a pair of standard eyeglasses for correcting myopia, wherein an auxiliary optical film or membrane extracted from the kits or sets disclosed herein is applied to the pair of standard eyeglasses over substantially the entire surface area of ​​the left eyeglass lens to convert the pair of standard single-vision eyeglasses into a pair of myopia management eyeglasses, wherein a method for distributing the auxiliary optical film or membrane is described herein.

[0139] The left portion of FIG14 shows a pair of standard single-vision eyeglass lenses 1400 having a right lens 1401 and a left lens 1402, which can be used to correct myopic refractive errors with or without astigmatism.

[0140] The right portion of FIG14 shows an example embodiment including an optical film or membrane designed to substantially cover the left lens 1402 indicated by the dashed boundary; wherein the optical film or membrane is configured with a substantially flat power across the optical film or membrane and is configured with an elliptical optical element 1405 such that the optical element falls within the upper region of the left lens of the eyeglass lens.

[0141] The optical film or sheet can be peeled off using portion 1404 of the film, thereby allowing the optical film or sheet to be placed on the eyeglasses.

[0142] In this example, the major axis and minor axis of the elliptical optical element are approximately 4 mm and 3 mm, respectively. The elliptical optical element is configured with an astigmatic power distribution or torus power distribution represented by two principal meridians—dashed line 1406 and solid line 1407. In some examples, the non-permanent auxiliary optical film or sheet configured with at least one elliptical optical element of the present invention includes an adhesive backing to adhere the optical sheet or film to a standard single-vision lens. The non-permanent adhesive backing can be peelable, self-adhesive, or any other suitable adhesive device to adhere the non-permanent auxiliary optical film or sheet to a standard single-vision lens. In some other examples, the non-permanent auxiliary optical film or sheet can be configured with at least two or three optical elements; each optical element has the astigmatic power distribution or torus power distribution of the present invention. Specification 15 / 30 pages 23 CN 121254519 A

[0143] Figure 15 illustrates an array of readily available, non-permanent auxiliary optical sheets or films encapsulated in a kit or set disclosed herein, suitable for use over the entire surface area of ​​a pair of standard single-vision glasses described in Figure 14 during a specified period (1 to 6) as described herein.

[0144] In the example of Figure 15, the right and left portions of the set or kit containing the optical film or sheet are configured with an elliptical optical element characterized by the astigmatic power distribution or torus power distribution disclosed herein. In this example, the different positioning or location of the optical element within the optical film or sheet and its application on a standard single-vision lens for myopia correction provide the eye with an optical stopping signal or stimulus that varies temporally and spatially.

[0145] In the example of Figure 15, the dimensions of the individual elliptical optical elements within the set or kit of optical sheets vary between 3 mm and 6 mm along the major axis and between 2 mm and 4 mm along the minor axis.

[0146] In these examples, the astigmatic power distribution within each optical element is represented by two principal meridians, with the solid line representing a weaker positive meridional power and the dashed line representing a stronger positive meridional power.

[0147] In other examples, the signs for positive and negative meridional power may differ. In the example of FIG15, elliptical optical elements disposed within an optical film are positioned in various locations, the optical film to be adhered to a standard monocular lens, thereby substantially covering the entire lens.

[0148] For example, in the first time period of FIG15, the right and left optical films have respective optical elements disposed below and above, respectively. In the second, third, and fourth time periods, the right and left optical films have optical elements disposed on the temporal and nasal sides, respectively.

[0149] In the fifth time period, the right and left optical films have optical elements disposed below the temporal side and above the nose, respectively. In the sixth time period, the right and left optical films have optical elements centrally configured to be stacked at the optical center of the monocular lens.

[0150] Furthermore, in the first two time periods of FIG15, the axis or orientation of astigmatism, represented by the stronger principal meridian (dashed line), is configured in a horizontal direction. In the third and sixth time periods of FIG15, the axis or orientation of astigmatism, represented by the stronger principal meridian (dashed line), is configured in a vertical direction.

[0151] In the fourth and fifth time periods of FIG15, the axis or orientation of astigmatism, represented by the stronger principal meridian (dashed line), is configured in an inclined direction. In some other examples, the dimensions of the individual elliptical optical elements within the set or kit of optical sheets may vary between 3 mm and 8 mm in the major axis and between 1 mm and 3 mm in the minor axis.

[0152] FIG16 illustrates another array of off-the-shelf, non-permanent auxiliary optical sheets or films packaged in a kit or set, whichSuitable for use on approximately the entire surface area of ​​a pair of standard single-vision glasses described in FIG14.

[0153] The optical film or sheet of FIG16 is configured for use during the six (6) different wearing periods described herein.

[0154] In the example of FIG16, the exemplary embodiment includes a set or kit of non-permanent auxiliary optical films or sheets designed to substantially cover the right and left lenses of a pair of standard single-vision glasses for myopia correction in FIG14; wherein the optical film or sheet is configured to have a substantially flat focal power across the optical film or sheet, and is also configured to have at least two elliptical optical elements within the optical film or sheet. The optical film or sheet can be peeled off, thereby allowing the optical film or sheet to be placed on the right or left lens of the appropriate single-vision lens. In some examples, the six (6) wearing periods described in FIG15 and FIG16 may be each day of the week, such as Monday to Saturday or Sunday to Friday. In some other examples, the six (6) wearing periods may be every other day of the week; while in some other examples, the six (6) wearing periods may include specific days of the month, such as the 1st, 5th, 10th, 15th, 20th and 25th of each month.

[0155] Figure 17 illustrates another pair of standard monocular glasses for myopia correction, with permanent auxiliary micro-optical elements applied only to a local area of ​​the spectacle lens on page 16 / 30 of the specification, CN 121254519 A, to convert the pair of standard monocular glasses into a pair of myopia management glasses, wherein a method for distributing non-permanent auxiliary micro-optical elements is described herein. In this example, the left side portion of Figure 17 shows a pair of standard spectacle lenses 1700 with a right lens 1701 and a left lens 1702, which can be used to correct myopia refractive errors with or without astigmatism. The optical centers of the right and left lenses are indicated by 1703.

[0156] The region of interest 1704 on the spectacle lens can be identified by marking the inner and outer boundaries, which are depicted in dashed lines. Additionally, some locations can be identified as areas where optical elements will be placed, indicated by crosses that can be engraved within the matrix of the monocular lens for easy positioning markings, such as 1705. The right-hand portion of Figure 17 shows an example embodiment including a micro-optical element to be placed on a selected area of ​​the right lens marked by cross 1705 and exemplified by solid boundaries; wherein the micro-optical element is configured such that it falls into the lower region of the right monocular lens. The micro-optical element can be partially peeled off using 1707, thereby allowing the micro-optical element to be placed on the monocular lens.

[0157] Figure 18 illustrates an array of optical sheets or films comprising encapsulations in sleeves configured for four (4) different time periods.Ready-made, non-permanent auxiliary micro-optical elements in multiple subgroups within a kit or set. The micro-optical elements are only suitable for use on localized areas of a pair of standard eyeglasses described in Figure 17. For example, group A of Figure 18 has elliptical optical elements with a major axis dimension of 4 mm and a minor axis dimension of 3 mm.

[0158] In this example of Figure 18, group C has circular optical elements with a diameter of 3 mm. In this example, group B of Figure 18 has elliptical optical elements with a major axis dimension of 5 mm and a minor axis dimension of 3 mm, and group D of Figure 18 has elliptical optical elements with a major axis dimension of 7 mm and a minor axis dimension of 3 mm.

[0159] In this example of Figure 18, a specific or predetermined location on the eyeglass lens can be defined using laser engraving made in the form of dots, lines, or cross-shaped patterns on the lens. Furthermore, methods of defining a set or kit include the wearer attaching or adhering the micro-optical elements to designated areas of the eyeglass lens for a specific period of time.

[0160] FIG19 illustrates the use of the micro-optical elements described in groups A through D of FIG18, each group comprising an array of readily available, non-permanent auxiliary micro-optical elements of similar design. In this example, during a first time period, the micro-optical elements of groups A and B are configured on selected areas of the left and right spectacle lenses for correcting myopia with or without astigmatism, maintaining symmetry along the vertical axis in this example.

[0161] During a second time period, the micro-optical elements are extracted only from group B and configured on selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis. During a third time period, all micro-optical elements are extracted only from group B of FIG18 and configured on selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis. During a fourth predetermined time period, all micro-optical elements are extracted from groups B and D of FIG18 and configured on selected areas of the left and right spectacle lenses, without maintaining symmetry along the vertical axis.

[0162] In the fifth time period, all three micro-optical elements are extracted only from group A of FIG18 and arranged in selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis; the elements are arranged such that the principal meridians are arranged in the horizontal / vertical dimension.

[0163] In the sixth time period, all three micro-optical elements are extracted only from group A of FIG18 and arranged in selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis; the elements are arranged such that the principal meridians are arranged in the tilt dimension.

[0164] FIG20 illustrates a standard single-vision ready-made spectacle blank typically used for correcting myopia with or without astigmatism, cut into an elliptical lens 2000 to fit a spectacle instruction manual with a short diameter of 20 mm and a long diameter of 25 mm.Page 17 / 30, 25 CN 121254519 A frame. The spectacle lens 2000 is configured with a non-permanent auxiliary micro-optical element 2005 including an astigmatic power distribution or annular power distribution, which is extracted from the kit or group C disclosed in FIG18.

[0165] In this example, the standard spectacle lens is configured with a region of interest defined around an optical center 2001, wherein an inner diameter of approximately 8 mm, indicated by dashed line 2003, and an outer diameter of approximately 15 mm, indicated by solid line 2002, form a region of interest 2004, which is identified for positioning the non-permanent auxiliary micro-optical element. The standard monovision ready-made spectacle blank of FIG20 has a -3D base prescription for correcting -3D myopia in the eye.

[0166] The non-permanent auxiliary micro-optical element 2005 is positioned approximately 5 mm from the geometric center 2001 of the spectacle lens 2000. The non-permanent auxiliary micro-optical element 2005 is configured to have an astigmatic power of +1.5 DC, represented by two principal focal length meridians, -2.5 D along the nasotemporal direction of the standard spectacle lens, and approximately -1 D along the vertical direction of the standard spectacle lens. The upper, temporal, lower, and nasal portions of the standard spectacle lens are represented by the characters S, T, I, and N, respectively.

[0167] Figure 21 illustrates a wide-field ray tracing schematic of a -3 D myopic eye corrected using the exemplary embodiment described in Figure 20; this ray tracing pattern includes three field angles when the spectacle lens is used in conjunction with the model eye of Table 1. The ray beams represented pass through: (a) the temporal portion of the lens (-15, 0); (b) the central portion of the lens (0, 0); and (c) the nasal portion of the lens (15, 0).

[0168] As seen in FIG. 21, the single ray beam passing through the temporal portion of the lens encounters the non-permanent auxiliary micro-optical element 2005, thereby providing the desired optical stop signal at the corresponding retinal location. Ray beams passing through the central and nasal portions of the spectacle lens do not exert any optical stop signal at the desired retinal location.

[0169] FIG. 22 illustrates the point spread function in a wide field of view when incoming light is incident on a -3D myopia model eye corrected using the exemplary embodiment described in FIG. 20.

[0170] As seen in FIG. 22, the ray beam passing through the non-permanent auxiliary micro-optical element 2005 produces a point spread function 2201, which, compared to 2203 formed when the ray beam passes through a portion of the spectacle lens without micro-optical elements, is influenced by the additional astigmatic power distribution or torus power distribution within the micro-element, thereby producing the desired directional cue or optical stop signal. The central ray beam passing through the base spectacle lens produces an ideal point spread function 2202.

[0171] Figure 23 illustrates the spatial variation of the signal depicted as a wide-angle defocus spot pattern. The optical performance of the spectacle lens used in conjunction with the model eye in Table 1 is represented in various field angles when incoming light of visible wavelengths is incident on a -3D myopia model eye corrected using an exemplary embodiment described in Figure 20.

[0172] The rows represent defocus spot patterns formed when the ray beam passes through three different regions of the spectacle: (a) the first row represents the defocus spot pattern when the incoming ray beam passes through a non-permanent auxiliary micro-optical element located on the temporal side of the spectacle lens; (b) the second row represents the data obtained when the incoming ray beam passes through a spectacle lens without an auxiliary micro-optical element; and (c) the third row represents the display data obtained when the incoming ray beam passes through the nasal side portion of a spectacle lens without an auxiliary optical element.

[0173] As can be seen from Figure 23, the ray beam passing through the non-permanent auxiliary micro-optical element produces a Sturm cone comprising an elliptical tangential blur pattern 2301 and a sagittal blur pattern 2302 approximately in front of the regionalized retina. However, when the incoming light passes through the central or nasal portion of the lens, i.e., through an area with virtually no micro-optical elements, no obvious Sturm cone is observed in front of or around the retina.

[0174] In this example, the length, position, and orientation of the Sturm cone contribute to an directional cue or optical stop signal to reduce the wearer's rate of myopia progression. In some embodiments, the astigmatic power of the micro-optical elements and their position on the single-vision lens are optimized to keep the entire Sturm cone in front of the peripheral retina; however, in other embodiments, as described on pages 18 / 30 of CN 121254519 A, the optimization of the micro-optical elements allows the Sturm cone to be positioned around the retina, wherein the tangential plane and the sagittal plane cross the retina.

[0175] Prescribed methods of altering the position of the micro-optical elements on the single-vision lens provide temporal and spatial variations for the directional cue or stop signal; such that the efficacy of myopia management can be maintained constant over time.

[0176] In the example of FIG24, the effect of modeling using a non-permanent auxiliary micro-optical element extracted from one of the groups or kits A to D described in FIG18, combined with a prescribed method of the standard single-vision basic spectacle lens described in FIG17, is discussed. For example, defocus spot patterns and point spread functions on the retina were analyzed for three different configurations. These three configurations depict the following situation: a method using a non-permanent auxiliary micro-optical element with an astigmatic power distribution or annular power distribution as described in FIG18 at a prescribed spatial location on the spectacle lens—approximately 5 mm from the optical center, but in a manner specified below; wherein the specified method includes using the lower principal power meridian of the micro-optical element.Three different axes / orientations are described for using the micro-optical element: (a) 90 degrees; (b) 225 degrees; and (c) 315 degrees. Figure 24 illustrates the spatially and temporally varying signals depicted when the micro-optical element is used in the prescribed manner.

[0177] Figure 25 illustrates a standard single-vision ready-made spectacle blank cut into a circular lens with a diameter of 30 mm, typically used for correcting myopia with or without astigmatism, configured with auxiliary optical elements or films extracted from the kits or groups disclosed herein. The spectacle lens 2500 is configured with a non-permanent auxiliary micro-optical element 2505 comprising an astigmatic power distribution or an annular power distribution, which is extracted from the kit or group B disclosed in Figure 18.

[0178] In this example, the standard spectacle lens is configured with a region of interest defined around an optical center 2501, wherein an inner diameter of approximately 7 mm, indicated by dashed line 2503, and an outer diameter of approximately 25 mm, indicated by solid line 2002, form a region of interest 2504, which is identified for positioning the non-permanent auxiliary micro-optical element.

[0179] The standard single-vision ready-made lens blank of FIG25 has a -3D base prescription for correcting -3D myopia in the eye. The non-permanent auxiliary micro-optical element 2505 is positioned approximately 12 mm from the optical center of the spectacle lens 2500.

[0180] The non-permanent auxiliary micro-optical element 2505 is configured with an astigmatic power of +2.5 DC, indicated by two principal power meridians, along a tilt angle of approximately -2.5 D, and perpendicular to the tilt principal meridian of the standard spectacle lens of approximately 0 D. The upper, temporal, lower, and nasal portions of a standard spectacle lens are represented by the characters S, T, I, and N, respectively.

[0181] Figure 26 illustrates a wide-field ray tracing schematic of a -3D myopic eye corrected using the exemplary embodiment described in Figure 25; this ray tracing pattern includes three field angles when the spectacle lens is used in conjunction with the model eye of Table 1. The ray beams represented pass through: (a) the temporal portion of the spectacle lens (-20, 0); (b) the central portion of the lens (0, 0); and (c) the nasal portion of the spectacle lens (20, 0).

[0182] As seen from Figure 26, the only ray beam passing through the temporal portion of the spectacle lens encounters the non-permanent auxiliary micro-optical element 2005, thereby providing the desired optical stop signal at the corresponding retinal location. Ray beams passing through the central and nasal portions of the spectacle lens do not apply any optical stop signal at the desired retinal location. Figure 27 illustrates the point spread function in a wide field of view when incoming light is incident on a -3D myopia model eye corrected using the exemplary embodiment described in Figure 25.

[0183] As seen in Figure 27, the ray beam passing through the non-permanent auxiliary micro-optical element 2005 generates a point spread function 2703. Compared to 2701 formed when the ray beam passes through the lens portion of the spectacle without micro-optical elements, the point spread function 2703 is affected by the additional astigmatic power distribution or torus power distribution within the micro-element, thereby generating a desired directional cue or optical stop signal. The central ray beam passing through the base spectacle lens generates an ideal point spread function 2702. Specification 19 / 30 pages 27 CN 121254519 A

[0184] Figure 28 illustrates the spatially varying signal depicted as a wide-angle defocus spot pattern. When visible wavelengths of incoming light are incident on a -3D myopia model eye corrected using an example embodiment described in Figure 25, the optical performance of the spectacle lens used in conjunction with the model eye in Table 1 is shown in various field angles.

[0185] In this example, the rows represent defocused spot patterns formed when the ray beam passes through three different regions of the eyeglass: (a) the first row represents the display data obtained when the incoming ray beam passes through the temporal portion of the eyeglass lens without auxiliary optics; (b) the second row represents the data obtained when the incoming ray beam passes through the central portion of the eyeglass lens without auxiliary micro-optics; and (c) the third row represents the defocused spot pattern when the incoming ray beam passes through a non-permanent auxiliary micro-optics located on the nasal portion of the eyeglass lens.

[0186] As seen from FIG28, the ray beam passing through the non-permanent auxiliary micro-optics produces a Sturm cone, including an elliptical sagittal blur pattern 2801 and a tangential blur pattern 2802, generally in front of the regionalized peripheral retina. However, when the incoming light passes through the central or temporal portion of the eyeglass lens, i.e., through a region with essentially no micro-optics, no obvious Sturm cone is observed in front of or around the retina.

[0187] In this example, the length, position, and orientation of the Sturm cone formed on the peripheral retina are assumed to facilitate directional cues or optical stop signals to reduce the wearer's rate of myopia progression. In some embodiments, the astigmatic power or torus power of the micro-optical element and its position on the single-vision lens are optimized to keep the entire Sturm cone in front of the peripheral retina; however, in other embodiments, the optimization of the performance of the micro-optical element can position the Sturm cone around the retina, wherein the sagittal plane is on the retina. Prescribed methods for changing the position of the micro-optical element on the single-vision lens provide temporal and spatial variations for directional cues or stop signals; so that the efficacy of myopia management can be maintained constant over time.

[0188] Figure 29 illustrates a standard single-vision lens cut into an elliptical lens with a minor axis diameter of 25 mm and a major axis diameter of 30 mm.A standard monocular lens preform is configured with auxiliary optical elements or films extracted from the kits or groups disclosed herein. The lens 2900 is configured with a non-permanent auxiliary micro-optical element 2905 comprising an astigmatic power distribution or annular power distribution, extracted from kit or group B disclosed in FIG. 18.

[0189] In this example, the standard lens is configured with a region of interest defined around an optical center 2901, wherein an inner diameter of approximately 7 mm, indicated by dashed line 2503, and an outer diameter of approximately 20 mm, indicated by solid line 2902, form a region of interest 2904, which is identified for positioning the non-permanent auxiliary micro-optical element. The standard monocular lens preform of FIG. 29 has a -3D base prescription for correcting -3D myopia in the eye. The non-permanent auxiliary micro-optical element 2905 is positioned approximately 10 mm from the optical center 2901 of the lens 2900. The non-permanent auxiliary micro-optical element 2905 is configured with an astigmatic power of -2.5 DC, represented by two principal focal length meridians, approximately -2.5 D along the tilt angle and approximately -5 D perpendicular to the tilt principal meridian of the standard spectacle lens. The upper, temporal, lower, and nasal portions of the standard spectacle lens are represented by the characters S, T, I, and N, respectively.

[0190] FIG30 illustrates a wide field-of-view ray-tracing schematic diagram of a -3 D myopia eye corrected using the example embodiment described in FIG29; the ray-tracing pattern includes three field-of-view angles for the eyeglass wearer: a temporal field-of-view angle (-20, 0), a central field-of-view angle (0, 0), and (c) a nasal field-of-view angle (20, 0).

[0191] FIG30 illustrates a wide field-of-view ray-tracing schematic diagram of a -3 D myopia eye corrected using the example embodiment described in FIG29; the ray-tracing pattern includes three field-of-view angles when the spectacle lens is used in conjunction with the model eye of Table 1. The ray beams represented pass through: (a) the temporal portion (-20, 0) of the spectacle lens; (b) the central portion (0, 0) of the lens; and (c) the nasal portion (20, 0) of the spectacle lens. As seen from Figure 30, the only ray beam passing through the temporal portion of the spectacle lens encounters the non-permanent auxiliary micro-optical element 2905, thereby providing an optical stopping signal at the corresponding retinal location. Ray beams passing through the central and nasal portions of the spectacle lens do not provide any optical stopping signal at the desired retinal location.

[0192] Figure 31 illustrates the point spread function in a wide field of view when incoming light is incident on a -3D myopia model eye corrected using the example embodiment described in Figure 29. As seen from Figure 29, the ray beam passing through the non-permanent auxiliary micro-optical element 2905 encounters the non-permanent auxiliary micro-optical element 2905, thereby providing an optical stopping signal at the desired retinal location.The ray beam of the optical element 2905 generates a point spread function 3103, which, compared to 3101 formed when the ray beam passes through the lens portion of the spectacle without micro-optical elements, is influenced by the additional astigmatic power distribution or torus power distribution within the micro-elements, thereby generating a desired directional cue or optical stop signal. The central ray beam passing through the base spectacle lens generates an ideal point spread function 3102.

[0193] FIG32 illustrates the spatially varying signal depicted as a wide-angle defocus spot pattern. When visible wavelengths of incoming light are incident on a -3D myopia model eye corrected using an example embodiment described in FIG29, the optical performance of the spectacle lens used in conjunction with the model eye of Table 1 is shown at various field angles.

[0194] In this example, the rows represent defocused spot patterns formed when the ray beam passes through three different regions of the eyeglass: (a) the first row represents the display data obtained when the incoming ray beam passes through the temporal portion of the eyeglass lens without auxiliary optics; (b) the second row represents the data obtained when the incoming ray beam passes through the central portion of the eyeglass lens without auxiliary micro-optics; and (c) the third row represents the defocused spot pattern when the incoming ray beam passes through a non-permanent auxiliary micro-optics located on the nasal portion of the eyeglass lens.

[0195] As seen from Figure 32, the ray beam passing through the non-permanent auxiliary micro-optics produces a Sturm cone, including an elliptical sagittal blur pattern 3203 and a tangential blur pattern 3205, generally behind the regionalized retina. However, when the incoming light passes through the central or temporal portion of the eyeglass lens, i.e., through a region with essentially no micro-optics, no obvious Sturm cone is observed in front of or around the retina.

[0196] In this example, the length, position, and orientation of the Sturm cone formed on the peripheral retina are assumed to facilitate directional cues or optical stop signals to reduce the rate of myopia progression. The astigmatic power or torus power of the micro-optical element and its position on the single-lens reflex are optimized to keep the entire Sturm cone behind the retina; however, in other embodiments, the optimization of the micro-optical element may position the Sturm cone around the retina, wherein the tangential plane is on the retina.

[0197] Prescribed methods of altering the position of the micro-optical element on the single-lens reflex provide temporal and spatial variations for directional cues or stop signals; such that the efficacy of myopia management can be maintained constant over time.

[0198] In some other embodiments, the torus portion of the lens in the kit or assembly may be configured to account for the fixed astigmatism of the eye wearing the lens to achieve a satisfactory balance between desired visual performance and desired astigmatic blurring, thereby providing a stimulus to reduce or slow the rate of progression.

[0199] In some embodiments, the torus portion of a pair of spectacle lenses in a spectacle lens kit or group may be positioned, formed, or placed on an anterior surface, a rear surface, or a combination thereof. In some other embodiments, the torus portion of a pair of spectacle lenses in a spectacle lens kit or group is dedicated to specific features that generate a stopping signal, such as residual astigmatism having a sagittal or tangential focal line substantially in front of the retina.

[0200] In some other embodiments, variations or large variations in the optical signal received by the on-axis and / or off-axis regions of the retina are configured by the Sturm cone or spacer of astigmatism at the retinal plane, wherein the optical stopping signal means that a portion of the Sturm cone or spacer falls in front of the retina (i.e., producing meridional myopic astigmatism), while the remainder of the Sturm cone or spacer produces a focusing or hyperopic signal. The proportion of the Sturm cone or spacer that provides positive meridional astigmatic focus may be approximately 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%.

[0201] In some other embodiments, the torus surface of the lens of a kit or set of eyeglasses may be positioned, formed, or placed on one of the two surfaces of the eyeglasses lens, and the other surface may have additional features to further reduce eye growth.

[0202] For example, additional features such as defocus, coma, or spherical aberration are used. In some embodiments, the shape of the front and rear surfaces of a set or set of eyeglasses lenses may be described by one or more of the following: spherical, aspherical, extended odd polynomial, extended even polynomial, conical section, biconical section, torus surface, or Zernike polynomial.

[0203] In some other embodiments, the radial and / or azimuth power distribution at the visual center of the lens may be described by a suitable Zernike polynomial, Bessel function, Jacobi polynomial, Taylor polynomial, Fourier expansion, or a combination thereof.

[0204] In one embodiment of this disclosure, the stop signal may be configured using only astigmatism, astigmatic focal power profile, or torus focal power profile. However, in other embodiments, higher-order aberrations such as spherical aberration, coma, and triceps aberration may be combined with configured astigmatic blur or torus blur.

[0205] In some embodiments of this disclosure, the astigmatic focal power distribution or torus focal power distribution may be configured using the following expression: Focal power profile of the torus embodiment = spherical + cylindrical / 2 * (radial) * (azimuth) focal power distribution function. In some embodiments, the radial distribution function may take the form of radial focal power distribution = Cρ^2, where C is the dilation coefficient and Rho(ρ) is the normalized radial coordinate ρ0 / ρmax. Rho(ρ0) is the radial coordinate at a given point on the lens, while ρmax is the maximum radial coordinate or half-diameter of the visual field. In some embodiments, the azimuth power distribution function may take the form of azimuth power distribution = cos mθ, where m may be any integer between 1 and 6 in some embodiments, and Theta(θ) is the azimuth angle.

[0206] In other example embodiments, the induced astigmatic profile or torus profile—which is configured in the anterior part of the auxiliary spectacle for use alongside a pair of standard spectacle lenses to reduce, suppress, or control the rate of myopia progression in an individual—may be at least +0.5 DC, at least +0.75 DC, at least +1 DC, at least +1.25 DC, at least +1.5 DC, at least +1.75 DC, or at least +2 DC.

[0207] In some other exemplary embodiments, the induced astigmatic profile or torus profile—which is configured in the anterior part of the assistive lens for use alongside a pair of standard spectacle lenses to reduce, suppress, or control an individual's rate of myopia progression—may be between +0.5 DC and +2.5 DC, between +0.75 DC and +1.75 DC, between +1 DC and +3 DC, or between +1.25 DC and +2.5 DC.

[0208] In some other embodiments, the induced astigmatic profile or torus profile—which is configured in the anterior part of the assistive lens for use alongside a pair of standard spectacle lenses to reduce, suppress, or control an individual's rate of myopia progression—may also be supplemented with a positive spherical power of at least +0.5 D, at least +0.75 D, at least +1 D, at least +1.25 D, or at least +1.5 D. In some other embodiments, the supplemental spherical power may be at least -0.5 D, at least -0.75 D, at least -1 D, at least -1.25 D, or at least -1.5 D. In this context, the supplemental spherical power may be independent of refractive correction configured in a standard spectacle lens.

[0209] In some examples, the wear schedule of the care program may include instructions to change a pair of auxiliary spectacle front components at least every 4 hours, 8 hours, 12 hours, 24 hours, 48 ​​hours, 60 hours, or 72 hours.

[0210] As will be understood by those skilled in the art, the present invention can be used in combination with any of the devices / methods that have the potential to influence the progression of myopia. These devices / methods may include, but are not limited to, contact lenses, color filters, agents, behavioral changes, and environmental conditions of various designs.
