Technical Field

[0003] This disclosure relates to devices for managing eye length disorders, such as myopia. The invention includes devices and methods for prescribing, selecting, supplying, and fitting sets, stocks, or kits of paired myopia management glasses or eyeglass front components, wherein the devices 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 sets, stock pieces, 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 asymmetrical 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. Background Technology

[0005] Humans are born farsighted because the length of the eyeball is too short for the overall 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 ensure that the eye's optics match its length and maintain homeostasis. This process is called emmetropization.

[0007] The signal that directs the emmetropization process is initiated by the adjustment of the light energy received at the retina. Retinal image characteristics are monitored by biological processes that adjust the signal to start or stop, speed up or slow down eye growth. This process is coordinated between optics and eye length to achieve or maintain emmetropia. A deviation from this emmetropization process can potentially lead to refractive disorders, such as myopia. It is hypothesized that increased retinal activity suppresses eye growth, and vice versa.

[0008] In many regions of the world, particularly in East Asia, the incidence of myopia is increasing at an alarming rate. In individuals with myopia, the axial length of the eye does not match the overall power of the eye, resulting in the focusing of distant objects in front of the retina.

[0009] A pair of simple negative single vision lenses can correct myopia. While this device can optically correct the refractive error associated with eye length, this device does not address the underlying cause of the excessive eye growth in myopia progression.

[0010] The excessive eye growth in high myopia is associated with significant vision threatening conditions, such as cataract, glaucoma, myopic maculopathy, and retinal detachment. Therefore, there remains a need for specific optical devices for these individuals that not only correct the underlying refractive error, but also largely prevent excessive eye lengthening over time.

[0011] To date, a number of spectacle lens designs have been proposed to control the rate of myopia progression. The prior art includes the use of executive D-shapes and concentric bifocal spectacles, symmetric and asymmetric progressive addition lenses, simultaneous defocus zones on spectacle lenses, and spectacles with positive spherical aberration, also known as peripheral plus lenses. In other words, all designs have a certain degree of additional power related to the prescribed power of the lens, which is distributed symmetrically or asymmetrically in rotation on the optical axis of the spectacle.

[0012] Each of these options has its strengths and weaknesses with respect to slowing the progression of myopia in an individual. Some of the weaknesses are described herein.

[0013] For example, some of the problems of existing spectacle designs, which are based on various types of bifocal lenses or peripheral power addition, compromise the quality of vision at various other viewing angles by introducing significant vision impairments such as wobbling effects, image jumping, residual aberrations, peripheral distortions, etc.

[0014] These side effects are mainly attributed to multiple defocus zones, a significant level of multiple defocus zones or segments, or the use of a large amount of positive spherical aberration in the lens, or a large change in power within a given zone of the spectacle lens. Given the impact of compliance of the spectacle lens wear on the efficacy of these lenses, a significant reduction in visual performance can promote poor compliance, leading to a poor efficacy of these lenses.

[0015] Therefore, what is needed is a spectacle design for correcting myopia and slowing progression without causing at least one or more of the drawbacks discussed herein.

[0016] Furthermore, some prior art can not be aesthetically appealing to children, teenagers and young adults, such as the D-shaped bifocal spectacles, the demarcation line of the executive bifocal spectacles, etc. Other solutions will become apparent as discussed herein.

[0017] It appears that the methods disclosed in the prior art for addressing myopia progression can not meet the needs of individuals in one or more ways to provide effective myopia control solution lenses while effectively used in their daily lives. Therefore, systems involving kits and groups and methods of prescribing kits for addressing the problems disclosed herein become desirable.

[0018] One of the drawbacks of myopia management spectacles of the prior art is their associated high accessible cost, setting the entry barrier too high for the average person in need of a solution. Therefore, there is a need for devices and / or methods that provide a budget-friendly solution to the problem of myopia, which can improve the utilization of the solution by the population in need.

DETAILED DESCRIPTION

[0093] The efficacy of prior art spectacle designs was established by randomized controlled clinical trials. The duration of these trials that included the spectacle designs ranged between six months and three years, and the reported efficacy ranged between 10% and 50% compared to a single vision control lens.

[0094] A simple emmetropization linear model suggests that the size of the stop signal accumulates over time. In other words, the accumulated stop signal depends on the total amplitude of the exposure and not its temporal distribution.​​

[0095] In all clinical trials, one striking observation is the fact that almost all the effect on the slowing of progression rate occurs as an initial burst of therapeutic effect observed in the first 6 months to 12 months and seems to fade away over time. Therefore, a more reliable positive visual model consistent with the clinical results suggests that there can be a delay before the stop signal construction, then saturation occurs over time and there can be a decay in the effectiveness of the stop signal.

[0096] There is a need in the art for spectacle lenses that avoid or minimize this saturation effect by providing a stop signal that varies over time and over space, for example by means of a prescribed care regimen that requires switching of pairs of myopia management spectacle lenses from a group or kit during a prescribed period, or switching of pairs of myopia management lens fronts or non-permanent auxiliary optical films, sheets or micro-optics used in combination with standard single vision spectacle lenses. In addition to pairs of spectacle lenses from a group or kit prescribed according to a care regimen, the present disclosure also describes the use of groups or kits of auxiliary lens fronts and / or non-permanent optical films and micro-optics for use in combination with a pair of standard spectacle lenses prescribed according to a care regimen.

[0097] Therefore, there is a need for an optical intervention that has a mechanism to achieve a significantly greater and / or substantially consistent therapeutic effect over time in reducing and / or slowing myopia progression without significantly compromising visual performance. In one or more examples, a substantially consistent therapeutic effect over time can be considered to be at least 6 months, 12 months, 18 months, 24 months, 36 months, 48 months, or 60 months.

[0098] In this section, the present disclosure will be described in detail with reference to one or more embodiments, some of which are illustrated and supported by the accompanying drawings. Examples and embodiments are provided by way of explanation and should not be construed as limiting the scope of the present disclosure. The following description is provided with respect to several embodiments that can share common characteristics and features of the present disclosure. It should be understood that one or more features of one embodiment can be combined with one or more features of any other embodiment that can constitute additional embodiments. The functional and structural information disclosed herein should not be construed as limiting in any way, but should be construed merely as representative bases for teaching those skilled in the art to employ the disclosed embodiments and variations of these embodiments in various ways. The subheadings and related subject matter that have been 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 in the summary or claims of the entire present disclosure. The subheadings and related subject matter should not be used to interpret the scope or the limitations of the claims.

[0099] The risk of developing myopia or progressive myopia can be based on one or more of the following factors: genetics, race, lifestyle, environment, excessive near work, etc. Certain embodiments of the present disclosure are directed to people at risk of developing myopia or progressive myopia.

[0100] One or more of the following advantages are found in one or more disclosed optical devices and methods of myopia management kit. A set or a pair of myopia management spectacle lenses or spectacle front components, non-permanent auxiliary optical films, sheets or micro-optical elements or methods used with standard single vision spectacle lenses provide a stop signal to delay the rate of eye growth or stop eye growth (or state of refractive error) of the wearer’s eye based on a blur signal of astigmatism.

[0101] A set or a pair of myopia management spectacle lenses or spectacle front components, non-permanent auxiliary optical films, sheets or micro-optical elements or methods used with standard single vision spectacle lenses provide a stop signal that varies in time and in space to increase the effectiveness of managing progressive myopia. The invention contemplates devices and / or methods that are not based on spherical aberration or simultaneous vergence that suffer from a saturation effect of the therapeutic effect due to the rotational symmetry of the optical stop signal.

[0102] Figure 1 An uncorrected -3D myopic model eye (100) is shown. When incoming light rays (e.g., 101) of visible wavelengths (e.g., 589 nm) with a vergence of 0D are incident on an uncorrected myopic eye, the resulting image on the retina has a symmetric blur (102) caused by defocus. This schematic represents an on-axis geometric spot analysis at the retinal plane.

[0103] Figure 2 It shows when Figure 1 A schematic diagram of the on-axis geometric spot analysis at the retinal plane when a 3D myopic model eye (200) is corrected using a standard monocular lens of the prior art or a commercially available monocular lens (202). Here, in this example, when an incoming ray of a visible wavelength (e.g., 589 nm) with a convergence-divergence ratio of 0D (e.g., 201) is incident on the corrected myopic eye, the resulting image on the retina has a symmetrical, sharp focus (203).

[0104] Figure 3 It shows when Figure 1 A schematic diagram of on-axis through-focus geometric spot analysis at the retinal plane when a 3D myopic model eye (300) 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 0D 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 an elliptical blur pattern having a sagittal plane and a tangential plane (303a and 303b). Some exemplary embodiments involve a method of modifying the incoming ray 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 standard prescriptions for myopia correction, by using an astigmatic prescription or a torus prescription. In short, additional astigmatism prescriptions or torus prescriptions can be used to slow the rate of myopia progression by introducing astigmatism cues (i.e., stop signals) at the retinal level. In some implementations, the use of astigmatism cues obtained using a myopia management kit can be configured to provide stop signals that vary in time and space.

[0105] exist Figures 1 to 3 The illustrative model eye (Table 1) is selected for illustrative purposes. However, in other embodiments, illustrative ray-tracing model eyes such as those of Liou-Brennan and Escudero-Navarro can be used instead of the simple model eyes described above. 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 myopia 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 different degrees of myopic refractive errors, with or without astigmatism.

[0106] In example implementations, reference is made to a specific wavelength of 598 nm, however, it will be appreciated that one skilled in the art can extend 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 interpreted as limiting, but merely as an illustrative basis for teaching one skilled in the art to employ the disclosed implementations in various variations.

[0107] Certain implementations of the present disclosure relate to a myopia management kit or set that can provide a progressive myopic eye with a stop signal that varies in time and in space, in other words changes with retinal position over time, which is achieved with the help of a prescribed wear regime. Such a stop signal that varies in time and in space can minimize the inherent saturation effect of the observed therapeutic effect in the prior art.

[0108] In certain implementations, the toric portion of the myopia management spectacle lens or spectacle lens front component, when used in combination with a standard single vision spectacle lens, at least partially provides an on-axis correction for a myopic eye and at least partially creates a stop signal that varies in time and in space to reduce the rate of myopia progression when worn according to a care regime. In certain implementations, the induced astigmatism (i.e., stop signal) configured within the pair of myopia management spectacle lenses or spectacle lens fronts used in combination with a standard single vision spectacle lens of the kit or set can be at least +0.5 DC, +0.75 DC, +1 DC, or +1.25 DC. In certain implementations, the induced astigmatism configured within the pair of myopia management spectacle lenses or spectacle lens fronts used in combination with a standard single vision spectacle lens of the kit or set can be between +0.5 DC and +1.75 DC, +0.5 DC and +2 DC, or +0.5 DC and +2.5 DC.

[0109] Figure 4 A flowchart illustrating an example method of prescribing a myopia management spectacle lens kit or set to reduce, inhibit, or control the rate of myopia progression in an individual according to example aspects of the present disclosure is shown.

[0110] In this example, a base prescription for the left and right eyes of the individual is identified by performing a best objective or subjective refraction on each eye of the individual (401).

[0111] A suitable size and axis of an astigmatic or toric power distribution is selected in combination with the base prescription for at least two pairs of myopia management spectacles for the individual (402).

[0112] The at least two pairs of myopia management spectacles are configured to at least partially provide an on-axis correction for the eye and at least partially provide an on-axis astigmatic blur to act as a light signal for the eye (403).

[0113] Furthermore, the method of use of the at least two pairs of myopia management spectacle lenses prescribed under the care regimen provides a spatially and temporally varying stop signal to the eye (404).

[0114] In some examples, an appropriate level of astigmatism configured within the pair of myopia management spectacle lenses for use in conjunction with the standard single vision spectacle lenses of the kit or set can be at least +0.5 DC, +0.75 DC, +1 DC, +1.25 DC, or +1.75 DC.

[0115] In some examples, an appropriate level of astigmatism configured within the pair of myopia management spectacle lenses for use in conjunction with the standard single vision spectacle lenses of the kit or set can be between +0.5 DC and +1.75 DC, +0.5 DC and +2 DC, or +0.5 DC and +2.25 DC.

[0116] In some examples, an appropriate difference in axis orientation of the individual spectacle lenses of the pair of myopia management spectacle lenses can be at least 15 degrees, 30 degrees, 45 degrees, 60 degrees, or 75 degrees.

[0117] In some examples, an appropriate difference in axis orientation of the individual spectacle lenses of the pair of myopia management spectacle lenses can 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.

[0118] To demonstrate the effects of other embodiments, other schematic model eyes such as Atchison, Escudero-Navarro, Liou-Brennan, Polans, Goncharov-Dainty can be used in place of the schematic model eye described above.

[0119] An embodiment can also vary parameters among 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 schematic eye is used to simulate the optical performance results of example embodiments of the present disclosure.

[0120] The prescribed parameters of the schematic model eye used for optical modeling and performance simulation are listed in Table 1.

[0121] This prescription provides a -3D myopic eye defined for a monochromatic wavelength of 589 nm. The prescription described in Table 1 should not be interpreted as the necessary method to demonstrate the effects of the contemplated example embodiments. This prescription is simply one of many methods that can be used by those skilled in the art for optical simulation purposes.

[0137] Figure 10 The auxiliary spectacle front components of the set of four pairs of exemplary auxiliary spectacle front components (1000, 1010, 1020, 1030) are configured to have different astigmatism magnitude +1 DC to +2.5 DC and different cylinder axis orientation in each eye. Figure 10 The astigmatism prescription or the cyclofocal prescription of the pair of spectacle front components of the set of four pairs of exemplary auxiliary spectacle front components (1000, 1010, 1020, 1030) is represented in the form of a cross cylinder symbol with two main meridians, the solid line (1002, 1012, 1022, 1032) representing the main meridian with weaker positive power and the dashed line (1004, 1014, 1024, 1034) representing the main meridian with stronger positive power of the right lens of the four pairs of exemplary auxiliary spectacle front components.

[0138] For example, in the right lens of the spectacle front components, the cylinder axis orientation in the 1st pair, 2nd pair, 3rd pair and 4th pair of spectacle front components is 0 degree, 30 degree, 60 degree and 90 degree respectively. In the left lens of the spectacle front components, the cylinder axis orientation in the 1st pair, 2nd pair, 3rd pair and 4th pair of spectacle front components is 180 degree, 150 degree, 120 degree and 90 degree respectively. It is specified that the four pairs of auxiliary spectacle front components (1000, 1010, 1020, 1030) are used in different time periods. For example, each pair of auxiliary spectacle front components is changed every day, every two days, every three days, every 4 days, every 5 days, every 7 days, every 10 days, every 14 days or every 21 days.

Figure 10 The prescription of the right eye of the four pairs of exemplary spectacle front components (1000, 1010, 1020, 1030) illustrated in the set of four pairs of exemplary auxiliary spectacle front components (1000, 1010, 1020, 1030) is: 1st pair: plain / +1.5 DC x 180 (right, 1101); 2nd pair: plain / +1 DC x 120 (right eye, 1103); 3rd pair: plain / +2.5 DC x 150 (right eye, 1105) and 4th pair: plain / +2 DC x 90 (right eye, 1107). Figure 10The prescription for the left eye of the four pairs of exemplary spectacle front components (1000, 1010, 1020, 1030) illustrated in FIG. 1 is: 1st pair: PLANO / +1.5 DC x 180 (left, 1102); 2nd pair: PLANO / +1 DC x 60 (right eye, 1104); 3rd pair: PLANO / +2.5 DC x 30 (right eye, 1106) and 4th pair: PLANO / +2 DC x 90 (right eye, 1108).

[0140] When the four pairs of spectacle front components (1000, 1010, 1020, 1030) described in FIG. 1 are used in conjunction with a standard single vision spectacle lens for correcting myopia with or without astigmatism, the resulting temporally and spatially varying optical signal obtained by integrating the response over the four predetermined periods is illustrated in FIG. 2. Figure 10 Figure 12 When incoming light having a visible wavelength (589 nm) and 0D vergence is incident on a -3D myopic model eye corrected with the four pairs of auxiliary spectacle front components (1000, 1010, 1020, 1030) described in FIG. 1 under the prescribed care regimen, the depicted on-axis retinal point spread functions for the right eye (1201, 1203, 1205, 1207) and the left eye (1202, 1204, 1206, 1208) are calculated.

[0143] Figure 14 A pair of standard spectacles for correcting myopia to which an auxiliary optical sheet or film is applied over substantially the entire surface area of the left spectacle lens to convert said pair of standard single vision spectacles into a pair of myopia management spectacles is illustrated in FIG. 4, wherein a method of dispensing the auxiliary optical sheet or film is described herein.

[0144] ​​​Figure 14 The left side shows a pair of standard single-vision lenses 1400 with a right lens (1401) and a left lens (1402), which can be used to correct myopic refractive errors with or without astigmatism.

[0145] Figure 14 The right side shows an example embodiment including an optical film or sheet designed to substantially cover the left lens 1402 indicated by the dashed boundary; wherein the optical film or sheet is configured with a substantially flat focal length across the optical film or sheet and is configured with an elliptical optical element 1405 such that the optical element falls into the upper region of the left lens of the spectacle lens.

[0146] The optical film or sheet can be peeled off using the 1404 portion of the film, thus allowing the optical film or sheet to be placed on eyeglasses.

[0147] 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 the 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.

[0148] Figure 15 The illustration shows an array of readily available, non-permanent auxiliary optical sheets or films packaged in the kits or groups disclosed herein, suitable for use within the specified time periods (1 to 6) described herein. Figure 14 It is used on the entire surface area of ​​a pair of standard single-vision glasses as described in the text.

[0149] exist Figure 15 In one example, the right and left portions of the assembly or kit containing an 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 correcting myopia provide the eye with a temporally and spatially varying optical stopping signal or stimulus.

[0150] exist Figure 15In examples of the present disclosure, the dimensions of the individual oval optical elements within the set or kit of optical sheets vary between 3 mm and 6 mm in the long axis and between 2 mm and 4 mm in the short axis dimension.

[0151] In these examples, the astigmatic power profile within each of the optical elements is represented with two primary meridians, the solid line representing a weaker positive meridional power and the dashed line representing a stronger positive meridional power.

[0152] In other examples, the sign of the positive and negative meridional powers can be different. In Figure 15 In examples of the present disclosure, the oval optical elements configured within the optical film are configured in various positions, the optical film to be adhered to a standard single vision spectacle lens, so as to cover substantially the entire lens.

[0153] For example, in a first period of time, the right and left optical films have individual optical elements configured inferiorly and superiorly, respectively. In a second, third, and fourth period of time, the right and left optical films have optical elements configured temporally and nasally, respectively. Figure 15

[0154] In a fifth period of time, the right and left optical films have optical elements configured inferiormost and superiormost, respectively. In a sixth period of time, the right and left optical films have optical elements configured centrally so as to overlie the optical center of the single vision spectacle lens.

[0155] Further, in the first two periods of time of the present disclosure, the axis or orientation of the astigmatism, represented by the stronger primary meridian (dashed line), is configured to be in a horizontal direction. In Figure 15 the third and sixth periods of time of the present disclosure, the axis or orientation of the astigmatism, represented by the stronger primary meridian (dashed line), is configured to be in a vertical direction. Figure 15

[0156] In the fourth and fifth periods of time of the present disclosure, the axis or orientation of the astigmatism, represented by the stronger primary meridian (dashed line), is configured to be in an oblique direction. In some other examples, the dimensions of the individual oval optical elements within the set or kit of optical sheets can vary between 3 mm and 8 mm in the long axis and between 1 mm and 3 mm in the short axis dimension.

[0160] Figure 17 illustrates another pair of standard single vision glasses for correcting myopia, permanent auxiliary micro-optical elements are applied to said pair of standard glasses only on partial areas of the glasses lenses to convert said pair of standard single vision glasses into a pair of myopia management glasses, wherein a method of dispensing non-permanent auxiliary micro-optical elements is described herein. In this example, Figure 17 The left part of illustrates a pair of standard glasses lenses 1700 with a right lens 1701 and a left lens 1702, which can be used to correct myopic refractive errors with or without astigmatism. The optical centers of the right and left lenses are represented by 1703.

[0161] The area of interest 1704 on the glasses lenses can be identified by marking the inner and outer boundaries depicted in dashed lines. In addition, some locations can be identified as areas where the optical elements are to be placed, which are represented as crosses that can be engraved within the substrate of the single vision glasses lenses in order to facilitate the positioning marks, for example 1705. Figure 17 The right part of illustrates an example implementation including micro-optical elements to be placed on the selected areas of the right lens marked by the crosses 1705 and exemplified using solid boundaries; wherein the micro-optical elements are configured so that the optical elements fall in the lower area of the right single vision glasses lens. The micro-optical elements can be peeled off using the 1707 part, allowing the micro-optical elements to be placed on the single vision glasses.

[0162] Figure 18The illustration depicts an array of optical sheets or films comprising off-the-shelf, non-permanent auxiliary micro-optical elements encapsulated within multiple subgroups configured for use in four (4) different time periods. The micro-optical elements are only suitable for use in… Figure 17 It is used on a localized area of ​​a pair of standard eyeglasses as described in the text. For example, Figure 18 Group A has elliptical optical elements, which have a major axis dimension of 4 mm and a minor axis dimension of 3 mm.

[0163] exist Figure 18 In this example, group C has a circular optical element with a diameter of 3 mm. In this example, Figure 18 Group B has elliptical optical elements with a major axis dimension of 5 mm and a minor axis dimension of 3 mm, respectively, and Figure 18 Group D has elliptical optical elements with a major axis dimension of 7 mm and a minor axis dimension of 3 mm.

[0164] exist Figure 18 In this example, laser engraving, created in the form of dots, lines, or crosshairs, can be used to define specific or prescribed locations on the eyeglass lens. Furthermore, methods for specifying sets or kits include having the wearer attach or adhere micro-optical elements to designated areas of the eyeglass lens within a specific timeframe.

[0165] Figure 19 The diagram shows... Figure 18 The use of micro-optical elements described in groups A through D, 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.

[0166] In the second time period, micro-optical elements are extracted only from group B and positioned on selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis. In the third time period, all micro-optical elements are extracted only from group B. Figure 18 Group B was extracted and positioned over selected areas of the left and right spectacle lenses, maintaining symmetry along the vertical axis. During the fourth specified time period, all micro-optical elements were extracted from... Figure 18 Groups B and D were extracted and positioned on selected areas of the left and right eyeglass lenses, without maintaining symmetry along the vertical axis.

[0167] In the fifth time period, all three micro-optical elements were only from Figure 18Group A of the set of non-permanent auxiliary micro-optical elements 2005 is extracted and configured on selected areas of the left and right eyeglasses lenses, maintaining the symmetry along the ordinate; the elements are configured so that the main meridians are arranged in a horizontal / vertical dimension.

[0168] In the sixth period, all three micro-optical elements are extracted only from Figure 18 Group A of the set of non-permanent auxiliary micro-optical elements 2005 is extracted and configured on selected areas of the left and right eyeglasses lenses, maintaining the symmetry along the ordinate; the elements are configured so that the main meridians are arranged in a tilted dimension.

[0169] Figure 20 a standard single-vision ready-to-wear eyeglasses blank commonly used for correcting myopia with or without astigmatism is cut into an oval lens 2000 to fit the dimensions of a spectacle frame having a short diameter of 20 mm and a long diameter of 25 mm. Said eyeglasses lens 2000 is configured with a non-permanent auxiliary micro-optical element 2005 comprising an astigmatic power distribution or a toric power distribution, which element is extracted from the set or Group C disclosed in Figure 18

[0170] In this example, the standard eyeglasses lens is configured with a region of interest defined around the optical center 2001, where an inner diameter of about 8 mm, represented by the dashed line 2003, and an outer diameter of about 15 mm, represented by the solid line 2002, form a region of interest 2004, which is identified for positioning said non-permanent auxiliary micro-optical element. Figure 20 The standard single-vision ready-to-wear eyeglasses blank has a base prescription of -3D for correcting -3D myopia in an eye.

[0171] Said non-permanent auxiliary micro-optical element 2005 is positioned at a distance of about 5 mm from the geometric center (2001) of the eyeglasses lens 2000. Said non-permanent auxiliary micro-optical element 2005 is configured to have an astigmatic power of +1.5 DC represented by two main power meridians, -2.5 D along the naso-temporal direction of the standard eyeglasses lens, and about -1 D along the superior-inferior direction of the standard eyeglasses lens. The superior, temporal, inferior and nasal portions on the standard eyeglasses lens are represented by the characters S, T, I and N, respectively.

[0172] Figure 21 a wide-field ray tracing schematic of a -3D myopic eye corrected using the exemplary embodiment described in Figure 20

[0173] ​​As seen from Figure 21 the only ray bundle that passes through the temporal portion of the lens encounters the non-permanent auxiliary micro-optic element 2005, thereby providing the desired optical stop signal at the corresponding retinal location. Ray bundles that pass through the central and nasal portions of the spectacle lens do not impose any optical stop signal at the desired retinal location.

[0174] Figure 22 illustrates the point spread function on the wide field view when the incoming light rays are incident on a -3 D myopic model eye corrected with the exemplary embodiment described in Figure 20

[0175] As seen from Figure 22 the ray bundle that passes through the non-permanent auxiliary micro-optic element 2005 produces a point spread function 2201 that is affected by the additional astigmatic or toric power distribution within the micro-element, thereby producing the desired directional cue or optical stop signal, as compared to the point spread function 2203 that is formed when the ray bundle passes through the portion of the spectacle lens without the micro-optic element. The central ray bundle that passes through the base spectacle lens produces the ideal point spread function 2202.

[0176] Figure 23 illustrates the spatially varying signal depicted as a wide angle defocused spot diagram. When the incoming light rays of visible wavelengths are incident on a -3 D myopic model eye corrected with one exemplary embodiment described in Figure 20

[0177] The rows represent the defocused spot diagrams that are formed when the ray bundle passes through three different regions of the spectacle: (a) the first row represents the defocused spot diagram when the incoming ray bundle passes through the non-permanent auxiliary micro-optic element located on the temporal side of the spectacle lens; (b) the second row represents the data obtained when the incoming ray bundle passes through the spectacle lens without the auxiliary micro-optic element; and (c) the third row represents the data obtained that demonstrates when the incoming ray bundle passes through the nasal portion of the spectacle lens without the auxiliary optic element.

[0178] As seen from Figure 23 the ray bundle that passes through the non-permanent auxiliary micro-optic element produces a Sturm cone that includes an elliptical tangential blur pattern 2301 and a sagittal blur pattern 2302 in front of the regionalized retina. However, when the incoming light rays pass through the central portion or the nasal portion of the spectacle lens, i.e., through regions that are substantially free of micro-optic elements, no significant Sturm cone is observed in front of the retina or around the retina.

[0179] ​​In this example, the length, position and orientation of the stigmatic cone contribute to the directional cues or optical stop signal to reduce the progression rate of myopia in the wearer. In some embodiments, the astigmatic power and position on the single vision spectacle lens of the micro-optical element are optimized to keep the entire stigmatic cone in front of the peripheral retina, however in other embodiments, the optimization of said properties of the micro-optical element can position the stigmatic cone in the periphery of the retina, with the tangential and sagittal planes crossing the retina.

[0180] The prescribed method of varying the position of the micro-optical element on the single vision spectacle lens provides temporal and spatial variations of the directional cues or stop signal; allowing the efficacy of myopia management to be maintained constant over time.

[0181] In the example of Figure 24 , the effects modeled using the non-permanent auxiliary micro-optical element extracted from one of the sets or kits A to D described in Figure 18 , in combination with the standard single vision base spectacle lens described in Figure 17 , are discussed. For example, the defocused spot diagrams and point spread functions on the retina are analyzed for 3 different configurations. These three configurations depict the following cases: where the prescribed spatial position on the spectacle lens is about 5 mm from the optical center, but the prescribed non-permanent auxiliary micro-optical element with an astigmatic power distribution or toric power distribution described in Figure 18 is used in the following prescribed manner; where the prescribed method comprises using the micro-optical element with the following 3 different axes / orientations of the lower principal meridian of the micro-optical element: (a) 90 degrees; (b) 225 degrees; and (c) 315 degrees. Figure 24 The spatially and temporally varying signals depicted when the micro-optical element is used in the prescribed manner are illustrated.

[0182] Figure 25 A standard single vision ready-to-wear spectacle blank, typically used for correcting myopia with or without astigmatism, cut into a circular lens with a 30 mm diameter, configured with an auxiliary optical element or film extracted from the kits or sets disclosed herein is illustrated. The spectacle lens 2500 is configured with a non-permanent auxiliary micro-optical element 2505 comprising an astigmatic power distribution or toric power distribution, extracted from the set or kit B disclosed in Figure 18 .

[0183] In this example, the standard spectacle lens is configured with a region of interest defined around the optical center 2501, where an inner diameter of about 7 mm, represented by the dashed line 2503, and an outer diameter of about 25 mm, represented by the solid line 2002, form a region of interest 2504, which is identified for positioning said non-permanent auxiliary micro-optical element.

[0184] Figure 25 The standard single-vision ready-to-wear lens blank has a base prescription of -3D for correcting a -3D myopic eye. Said non-permanent auxiliary micro-optical element 2505 is positioned at a distance of about 12 mm from the optical center of the spectacle lens 2500.

[0185] Said non-permanent auxiliary micro-optical element 2505 is configured with a cylindrical power of +2.5 DC represented by two main power meridians, along an angle of tilt of about -2.5D, and about 0D perpendicular to the tilted main meridian of the standard spectacle lens. The superior, temporal, inferior and nasal portions on the standard spectacle lens are represented by the characters S, T, I and N, respectively.

[0186] Figure 26 Fig. 1 illustrates a schematic representation of a wide-field ray tracing of a -3D myopic eye corrected using the exemplary embodiment described in Figure 25 Fig. 2 illustrates a schematic representation of a wide-field ray tracing of a -3D myopic eye corrected using the exemplary embodiment described in

[0187] As seen from Figure 26 the only ray bundle passing through the temporal portion of the spectacle lens encounters said non-permanent auxiliary micro-optical element 2005, thereby providing the desired optical stop signal at the corresponding retinal location. The ray bundles passing through the central and nasal portions of the spectacle lens do not impose any optical stop signal at the desired retinal location. Figure 27 Fig. 3 illustrates a schematic representation of a point spread function on a wide-field view when an incoming light ray is incident on a -3D myopic model eye corrected using the exemplary embodiment described in Figure 25 Fig. 4 illustrates a schematic representation of a point spread function on a wide-field view when an incoming light ray is incident on a -3D myopic model eye corrected using the exemplary embodiment described in

[0188] As seen from Figure 27As seen, the ray bundle passing through the non-permanent auxiliary micro-optic element 2005 produces a point spread function 2703 that is affected by the additional astigmatic or toric power distribution within the micro-element compared to 2701 formed when the ray bundle passes through a portion of the spectacle lens without a micro-optic element, thereby producing the desired directional cue or optical stop signal. The central ray bundle passing through the base spectacle lens produces the ideal point spread function 2702.

[0189] Figure 28 The spatially varying signal is illustrated as a wide-angle through-focus spot diagram. When incoming light of visible wavelengths is incident on a -3D myopic model eye corrected with one example embodiment described in the Figure 25 The optical performance of the spectacle lens used in conjunction with the model eye of Table 1 is represented over a variety of field angles.

[0190] In this example, the rows represent through-focus spot diagrams formed when a ray bundle passes through three different regions of the spectacle: (a) the first row represents the data presented when the incoming ray bundle passes through the temporal portion of the spectacle lens without an auxiliary optical element; (b) the second row represents the data obtained when the incoming ray bundle passes through the central portion of the spectacle lens without an auxiliary micro-optic element; and (c) the third row represents the through-focus spot diagram when the incoming ray bundle passes through the non-permanent auxiliary micro-optic element located on the nasal portion of the spectacle lens.

[0191] As seen from the perspective of the eye, the ray bundle passing through the non-permanent auxiliary micro-optic element 2005 produces a point spread function 2703 that is affected by the additional astigmatic or toric power distribution within the micro-element compared to 2701 formed when the ray bundle passes through a portion of the spectacle lens without a micro-optic element, thereby producing the desired directional cue or optical stop signal. The central ray bundle passing through the base spectacle lens produces the ideal point spread function 2702. Figure 28 As seen, the ray bundle passing through the non-permanent auxiliary micro-optic element produces a Sturm cone comprising 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 portion or the temporal portion of the spectacle lens, i.e. through regions substantially without micro-optic elements, no significant Sturm cone is observed in front of the retina or around the retina.

[0192] In this example, the length, location and orientation of the Sturm cone formed on the peripheral retina is assumed to contribute to the directional cue or optical stop signal to reduce the rate of myopia progression in the wearer. In some embodiments, the astigmatic or toric power of the micro-optic element and its location on the single vision spectacle lens are optimized to maintain the entire Sturm cone in front of the peripheral retina, however in other embodiments, optimization of the performance of the micro-optic element can position the Sturm cone around the retina with the plane of least confusion on the retina. Prescribed methods of varying the location of the micro-optic element on the single vision spectacle lens provide temporal and spatial variations in the directional cue or stop signal; such that the efficacy of myopia management can be maintained constant over time.

[0193] Figure 29 A standard single vision spectacle blank cut into an elliptical lens with a minor axis diameter of 25 mm and a major axis diameter of 30 mm is illustrated, the standard single vision spectacle blank being configured with an auxiliary optical element or film extracted from the kit or set disclosed herein. Said spectacle lens 2900 is configured with a non-permanent auxiliary micro optical element 2905 comprising an astigmatic power distribution or a toric power distribution, the element being extracted from the kit or set B disclosed in Figure 18 .

[0194] In this example, the standard spectacle lens is configured with a region of interest defined around the optical center 2901, wherein an inner diameter of about 7 mm, represented by the dashed line 2503, and an outer diameter of about 20 mm, represented by the solid line 2902, form the region of interest 2904, which is identified for positioning said non-permanent auxiliary micro optical element. Figure 29 The standard single vision ready-to-wear spectacle blank has a base prescription of -3D for correcting a -3D myopic eye. Said non-permanent auxiliary micro optical element 2905 is positioned at a distance of about 10 mm from the optical center 2901 of the spectacle lens (2900). Said non-permanent auxiliary micro optical element 2905 is configured with an astigmatic power of -2.5 DC represented by two main power meridians, along an angle of inclination of about -2.5D and about -5D perpendicular to the inclined main meridian of the standard spectacle lens. The upper, temporal, lower and nasal portions on the standard spectacle lens are represented by the characters S, T, I and N, respectively.

[0195] Figure 30 Figure illustrates a wide field of view ray tracing schematic of a -3D myopic eye corrected using the example embodiment described in Figure 29 . This ray tracing pattern comprises three field of view angles for the spectacle wearer: (a) a temporal field of view angle (-20, 0), (b) a central field of view angle (0, 0) and (c) a nasal field of view angle (20, 0).

[0196] Figure 30 Figure illustrates a wide field of view ray tracing schematic of a -3D myopic eye corrected using the example embodiment described in Figure 29 . This ray tracing pattern comprises three field of view angles for the spectacle wearer: (a) a temporal field of view angle (-20, 0), (b) a central field of view angle (0, 0) and (c) a nasal field of view angle (20, 0). Figure 30As seen in FIG. 29, the only bundle of rays that passes through the temporal portion of the spectacle lens encounters the non-permanent auxiliary micro-optic element 2905, thereby providing the desired optical stop signal at the corresponding retinal location. The bundles of rays that pass through the central and nasal portions of the spectacle lens do not impart any optical stop signal at the desired retinal location.

[0197] Figure 31 FIG. 29 illustrates the point spread function on a wide field of view when incoming light rays are incident on a -3 D myopic model eye corrected with an example embodiment described in Figure 29 Figure 29 As seen in FIG. 29, the bundle of rays that passes through the non-permanent auxiliary micro-optic element 2905 produces a point spread function 3103 that is affected by the additional astigmatic or toric power distribution within the micro-element compared to 3101 formed when the bundle of rays passes through the portion of the spectacle lens without the micro-optic element, thereby producing the desired directional cue or optical stop signal. The central bundle of rays that passes through the base spectacle lens produces the ideal point spread function 3102.

[0198] Figure 32 FIG. 29 illustrates the point spread function on a wide field of view when incoming light rays are incident on a -3 D myopic model eye corrected with an example embodiment described in Figure 29

[0199] In this example, the rows represent the off-focus spot diagrams formed when the bundle of rays passes through three different regions of the spectacle: (a) the first row represents the data presented when the incoming bundle of rays passes through the temporal portion of the spectacle lens without the auxiliary optical element; (b) the second row represents the data obtained when the incoming bundle of rays passes through the central portion of the spectacle lens without the auxiliary micro-optic element; and (c) the third row represents the off-focus spot diagram when the incoming bundle of rays passes through the non-permanent auxiliary micro-optic element located on the nasal portion of the spectacle lens.

[0200] As seen in FIG. 29, the bundle of rays that passes through the non-permanent auxiliary micro-optic element 2905 produces a point spread function 3103 that is affected by the additional astigmatic or toric power distribution within the micro-element compared to 3101 formed when the bundle of rays passes through the portion of the spectacle lens without the micro-optic element, thereby producing the desired directional cue or optical stop signal. The central bundle of rays that passes through the base spectacle lens produces the ideal point spread function 3102. Figure 32 As seen in FIG. 29, the bundle of rays that passes through the non-permanent auxiliary micro-optic element 2905 produces a point spread function 3103 that is affected by the additional astigmatic or toric power distribution within the micro-element compared to 3101 formed when the bundle of rays passes through the portion of the spectacle lens without the micro-optic element, thereby producing the desired directional cue or optical stop signal. The central bundle of rays that passes through the base spectacle lens produces the ideal point spread function 3102.

[0201] ​​In this example, the length, position and orientation of the stroma cone formed on the peripheral retina is assumed to contribute to the directional cue or optical stop signal to cause the rate of myopia progression to decrease. The astigmatic or toric power of the micro-optic element and the position on the single vision spectacle lens is optimized to keep the entire stroma cone behind the retina, however in other embodiments the optimization of the micro-optic element can position the stroma cone around the retina with the tangential plane on the retina.

[0202] The prescribed method of varying the position of the micro-optic element on the single vision spectacle lens provides temporal and spatial variation of the directional cue or stop signal; allowing the efficacy of myopia management to be maintained constant over time.

[0203] In certain other embodiments, the toric portion of the spectacle lenses in the kit or set can be configured to take into account the paretic astigmatism of the eye wearing the lenses to achieve a satisfactory balance between the desired visual performance and the desired astigmatic blur, thereby providing the stimulus to cause the rate of progression to decrease or slow down.

[0204] In some embodiments, the toric portion of a pair of spectacle lenses of the kit or set of spectacle lenses can be positioned, formed or placed on the front surface, on the back surface, or a combination thereof. In some other embodiments, the toric portion of a pair of spectacle lenses of the kit or set of spectacle lenses is dedicated to a specific feature to generate a stop signal, for example a residual astigmatism with a sagittal or tangential focal line substantially in front of the retina.

[0205] In certain other embodiments, the variation or substantial variation of the optical signal received by the on-axis and / or off-axis regions on the retina is configured by a stroma cone or gap of astigmatism at the plane of the retina, where the optical stop signal means that a portion of the stroma cone or gap falls in front of the retina (i.e. creates a meridional myopic defocus) while the rest of the stroma cone or gap creates a focus or hyperopic signal. The proportion of the stroma cone or gap that provides positive meridional astigmatic focus can be about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 100%.

[0206] In certain other embodiments, the toric of the spectacle lenses of the kit or set can be positioned, formed or placed on one of the two surfaces of the spectacle lenses and the other surface can have other features to further reduce the eye growth.

[0207] For example, additional features such as defocus, coma, or spherical aberration are used. In certain embodiments, the shape of the front and back surfaces of a set or a group of spectacle lenses can be described by one or more of the following: spherical, aspherical, extended odd polynomial, extended even polynomial, conic section, biconic section, toric surface, or Zernike polynomials.

[0208] In some other embodiments, the radial and / or azimuthal power profile on the visual center of the lens can be described by appropriate Zernike polynomials, Bessel functions, Jacobi polynomials, Taylor polynomials, Fourier expansion, or combinations thereof.

[0209] In one embodiment of the disclosure, the stop signal can be configured using only astigmatism, astigmatism power profile, or toric power profile. However, in other embodiments, higher order aberrations such as spherical aberration, coma, trefoil aberration can be combined with the configured astigmatic blur or toric blur.

[0210] In certain embodiments of the disclosure, the astigmatism power profile or the toric power profile can be configured using the following expression: Toric embodiment power profile = spherical + cylindrical / 2*(radial)*(azimuthal) power profile function. In some embodiments, the radial profile function can take the form of radial power profile = Cρ^2, where C is a coefficient of expansion and Rho(ρ) is a normalized radial coordinate ρ0 / ρ max . Rho(ρ0) is the radial coordinate at a given point on the lens, while ρ max is the maximum radial coordinate or semi-diameter of the optic zone. In some embodiments, the azimuthal power profile function can take the form of azimuthal power profile = cos mθ, where m can be any integer between 1 and 6 in some embodiments, and Theta(θ) is the azimuthal angle.

[0211] In other example embodiments, the induced astigmatic profile or toric profile, which is configured in the auxiliary spectacle front piece to be used in juxtaposition with a pair of standard spectacle lenses to reduce, suppress, or control the rate of progression of myopia in an individual, can 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.

[0212] In some other example embodiments, the induced astigmatic profile or toric profile configured in the auxiliary eyewear front piece to be used in parallel with a pair of standard eyeglasses lenses to reduce, inhibit or control the rate of progression of myopia in an individual can 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.

[0213] In certain other embodiments, the induced astigmatic profile or toric profile configured in the auxiliary eyewear front piece to be used in parallel with a pair of standard eyeglasses lenses to reduce, inhibit or control the rate of progression of myopia in an individual can also be supplemented with a 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 certain other embodiments, the supplemental spherical power can 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. The supplemental spherical power in this context can be independent of the refractive correction configured in the standard eyeglasses lenses.

[0214] In certain examples, the wear schedule of the care regimen can include instructions to change the pair of auxiliary eyewear front pieces at least every 4 hours, 8 hours, 12 hours, 24 hours, 48 hours, 60 hours, or 72 hours.

[0215] As will be appreciated by those skilled in the art, the present application can be used in combination with any of the devices / methods that have the potential to affect myopia progression. These devices / methods can include, but are not limited to, contact lenses of various designs, filters, pharmaceutical agents, behavioral changes, and environmental conditions.
