[0002] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 596,058, filed on November 3, 2023, entitled “Wavelength Selective Ophthalmic Lens,” and U.S. Provisional Patent Application No. 63 / 480,848, filed on January 20, 2023, entitled “Wavelength / Color Components of Therapeutic Ophthalmic Lenses,” the disclosures of which are incorporated herein by reference in their entirety. Background Art

[0003] Myopia (often referred to as "near-sightedness") is a progressive eye disease with a high and increasing prevalence. Myopia involves a refractive error, usually caused by an eyeball that is too long, causing the image formed by the lens to focus in front of the retina rather than on it, which causes objects far away from the eye to appear blurry. A schematic diagram of this process is shown below. Figure 1 shown.

[0004] Several different types of lens designs have been studied and shown to have potential efficacy in controlling myopia. These lens designs include multifocals (e.g., bifocals, trifocals) and aspheric lens optics. These lens designs have been used in both eyeglasses and contact lenses. Overall, these lens designs have shown a significant reduction in myopia progression and axial growth. The effectiveness of these lens designs has been shown to depend on various factors, such as longer wear and a faster rate of myopia progression.

[0005] Another example of a lens design previously used to treat myopia is the Directional Defocus Multi-Segmented (DIMS) lens, which helps the eye develop proper refractive properties (emmetropization). Figure 2 As shown, DIMS lenses can utilize a series of smaller "lenses" that are stacked at selected locations to enhance the lens's corrective power. These lenslets are typically small, round, and arranged in a circular pattern centered around the wearer's pupil. An example of a DIMS lens is shown and described in U.S. Patent No. 11,029,540, the entire contents of which are hereby incorporated by reference.

[0006] like Figure 3 As shown, the eye focuses slightly differently for different wavelengths of light. There's also evidence that eye growth can be guided by color stimuli. Eye physiology suggests that longer wavelengths of light can control this process. When these wavelengths are detected as blurry, the eye attempts to correct by shortening its axial growth, allowing the eye to perceive images accurately as it matures.

[0007] It would therefore be desirable to provide an ophthalmic lens for treating myopia that combines the use of lenslets with the use of color. Summary of the Invention

[0025] Specific embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. The terminology used in describing the embodiments shown in the accompanying drawings is not intended to be limiting of the present invention. In the drawings, like numbers refer to like elements.

[0026] For the purposes of this specification, when referring to a value, the use of the terms "about," "approximately," or "approximately" can be understood to mean within 5% (including greater than or less than) of the stated value.

[0027] Disclosed herein are various embodiments of ophthalmic lenses, including spectacle lenses and contact lenses, that utilize color stimulation to treat various conditions, such as myopia, hyperopia, presbyopia, and migraines. The recognition that eye growth may be regulated by color stimulation has led to the development of various lens designs that incorporate color layers in a manner that influences axial growth of the eye, potentially enabling accurate image perception in mature eyes.

[0028] Typically, a tinted pattern can be printed on an ophthalmic lens, for example, by applying a tinted dye. The tinted pattern can be applied to an ophthalmic lens having multiple lenslets (e.g., a "DIMS lens"), the pattern can be applied to a base lens that is registered or aligned with one or more desired lenslets, the pattern can be applied to a laminate that is applied to a base lens, or the pattern can be applied directly to one or more of the lenslets.

[0029] The tinting pattern can be configured to apply wavelength-selective filtering to treat various conditions, such as myopia, hyperopia, presbyopia, migraines, etc. In certain exemplary embodiments, the tinting pattern can be configured to completely block or filter certain wavelengths. However, in other exemplary embodiments, the tinting pattern can be configured to only partially block or filter certain wavelengths.

[0030] There are various ways to incorporate tinted patterns into ophthalmic lenses. For example, a printed pattern can be applied directly to a base lens. Furthermore, a printed pattern can be incorporated into a laminate and then aligned with a desired pattern (e.g., a lenslet pattern) during the manufacturing process. The tinted pattern can be aligned with the portion of the ophthalmic lens that carries the added power, and the wavelength of the tinted pattern can be selected to achieve optimal clinical results based on the specific patient or condition being treated.

[0031] As another example, a tint layer can be applied directly to one or more lenslets formed on the surface of a base lens. The tint layer can be applied to all or only some of the lenslets. The tint layer can be applied to the lenslets before or after they are formed on the base lens. The lenslets can have the same or different correction powers. Some lenslets may not have any correction power.

[0032] The tint layer can be applied based on the correction power, so that it is only applied to lenslets with a certain correction power. The tint layer can be applied based on the location, so that it is only applied to certain lenslets at the desired location on the base lens.

[0033] Such lenses can be manufactured using a process similar to that used to prepare functionalized laminated lenses. The pattern can be printed onto a flat plate, which is then molded onto the lens. However, this process can have certain drawbacks or disadvantages, such as poor adhesion due to the steep substrate curve or difficulty ensuring concentricity between the corrective and tinting patterns.

[0034] Another method for manufacturing such lenses is to print the tint pattern directly onto the lens using a pad printing process, centered around the optical pattern. This method eliminates the need to align the printed pattern with the optical zone in subsequent steps. Once the printed pattern is exposed in this manner, applying a protective layer, such as a hard coat, may become more important. Therefore, a hard coat compatible with the ink used to print the tint pattern can be used to protect the tint pattern.

[0035] The tint layer is applied to the portion of the base lens that does not contain any lenslets. The tint layer on the base lens may or may not have a corrective power. The tint layer may be applied to a combination of the portion of the base lens that contains lenslets and the portion of the base lens that does not contain lenslets.

[0036] The tinted layer can be applied to portions of the base lens having different geometric shapes. For example, the tinted layer can be applied to the convex portion of the base lens, the concave portion of the base lens, and / or the planar (ie, substantially flat) portion of the base lens.

[0037] Various configurations of coloring patterns have been considered, including different patterns and / or different colors or hues to selectively filter or absorb different wavelengths of light. A blue or green coloring layer may be applied to absorb or filter longer wavelengths of light (such as the red or orange spectrum) while allowing shorter wavelengths of light (such as the blue or vivid spectrum) to pass through. Conversely, a red coloring layer may be applied to absorb shorter wavelengths of light while allowing longer wavelengths of light to pass through.

[0038] As a first example, a blue or green tint layer can be applied only to the non-corrective portion of the lens, including the base lens or one or more lenslets. As a second example, a reverse configuration can be employed, where the blue or green tint layer is applied only to the corrective (i.e., power-adding) portion of the lens (including the base lens or one or more lenslets).

[0039] As a third example, the red tint layer can be applied only to the non-corrective portion of the lens (including the base lens or one or more lenslets). As a fourth example, a reverse configuration can be employed, where the red tint layer is applied only to the addition power portion of the lens (including the base lens or one or more lenslets).

[0040] As a fifth example, both blue / green and red tint layers can be used, with the red tint layer applied to the non-corrective portion of the lens and the blue / green tint layer applied to the addition portion of the lens, including the base lens or one or more lenslets. As a sixth example, a reverse configuration can be employed, with the blue / green tint layer applied to the non-corrective portion of the lens and the red tint layer applied to the addition portion of the lens, including the base lens or one or more lenslets.

[0041] However, it should be understood that any color of tinted layer may be used, and thus the present disclosure should not be construed as being limited to blue, green, or red tinted layers, which are used for illustrative purposes only. Thus, a variety of different colors or hues may be used depending on the wavelength of light to be filtered / absorbed and the length of light to be effectively passed.

[0042] Specific embodiments are as follows. However, it should be understood that any features in any embodiment can be mixed and matched with each other in any combination. Therefore, the present invention should not be limited to these embodiments, but should also include any broader combination thereof.

[0043] Figure 4Schematic diagram illustrating the application of the concept of an ophthalmic lens having concentric rings to a DIMS ophthalmic lens having a plurality of small lenses. Figure 4 As shown, it can be seen that both lenses can have focusing areas and defocusing areas.

[0044] In the DIMS configuration, a plurality of lenslets covers at least a portion of the base lens. Some or all of the lenslets in the plurality of lenslets may have a corrective power. Figure 4 As shown, in some exemplary embodiments, the lenslet groups may have a corrective power, while the lenslet groups may also have no corrective power (e.g., flat power). The lenslet groups with corrective powers may include adjacent lenslet groups formed into various shapes, such as the discontinuous small island-like structures shown in the figure, where the lenslets surrounding these discontinuous small island-like structures are composed of lenslets with different corrective powers or no corrective power at all.

[0045] In a concentric ring configuration, instead of using small islands to achieve the degree of defocus, the corrective portion can be achieved using concentric rings. This configuration can achieve the same effect as using small islands without the need for fine machining of small parts.

[0046] Figure 5-6 FIG. 1 shows an exemplary embodiment of a DIMS lens 100 having a plurality of small lenses 120 arranged on a base lens 110. Figure 5 An exemplary embodiment is shown in which a tinted layer has been applied to some, but not all, of the lenslets 120. Figure 6 An exemplary embodiment is shown in which a tinted layer has been applied to all of the lenslets 120 .

[0047] exist Figure 5 In the illustrated exemplary embodiment, the colored layer 130 has been applied to some but not all of the lenslets 120 , thereby forming a plurality of colored lenslets 130 that can be distinguished from the remaining lenslets 120 that are not coated with the colored layer.

[0048] like Figure 5 In the exemplary embodiment shown, the tinted lenslets 130 can be arranged in a concentric pattern around a central region devoid of lenslets. For example, the tinted lenslets 130 can be arranged in a continuous ring having a substantially circular or polygonal shape. It should be understood that this configuration is for illustrative purposes only and should not be construed as limiting the scope. Various patterns can be used for the tinted lenslets 130, or the tinted lenslets 130 can be randomly arranged within the lenslets 120 without a distinct pattern. In some exemplary embodiments, the tinted lenslets 120 may not form a continuous ring. Figure 5In some exemplary embodiments, the tinted lenslets 120 may be non-concentric, such as a single “ring” structure comprising the tinted lenslets 120 .

[0049] Figure 6 An exemplary embodiment is shown in which the tint layer 130 has been applied to all of the lenslets 120. These lenslets 120 may all have a corrective power, or in some examples, some or all of the lenslets 120 may have no corrective power at all.

[0050] In some exemplary embodiments, different lenslets 120 may have different correction powers. Thus, the lenslets 120 may all have the same correction power, or in some exemplary embodiments, one or more lenslets 120 may have a different correction power than the remaining one or more lenslets 120. In one exemplary embodiment, one or more lenslets 120 may include a positive correction power, a negative correction power, and / or zero correction power.

[0051] refer to Figure 5 In one exemplary embodiment, the tinted lenslets 130 may include a first correction power, while the remaining non-tinted lenslets 120 may include a second correction power, the first correction power and the second correction power being selected from the group consisting of a positive correction power, a negative correction power, and a zero correction power. As a non-limiting example, referring to Figure 5 , the tinted lenslets 130 may include a positive correction power (e.g., +2.5), and the remaining non-tinted lenslets 120 may include a zero correction power. As another non-limiting example, the tinted lenslets 130 may include different correction powers (e.g., a first plurality of tinted lenslets 130 may include a first correction power, a second plurality of tinted lenslets 130 may include a second correction power, and the first correction power and the second correction power are different from each other).

[0052] like Figure 5 As shown, the plurality of lenslets 120 may be arranged in a circular pattern, and the central region of the base lens 110 does not include any lenslets 120. However, it should be understood that Figure 5 The patterns shown in FIG. 1 are for exemplary purposes only, and thus their scope should not be construed as limited to any particular pattern. Different patterns of lenslets 120 may be used in different embodiments. In some exemplary embodiments, a majority of the base lens 110 may include lenslets 110 without an exposed central region.

[0053] In different embodiments, the size of the lenslet 120 and its coverage of the base lens 110 may vary. Figure 2 and Figure 5-6In the exemplary embodiment shown in the annular configuration, the radius of the central region of the substrate optic 110, excluding any lenslets 120, can be between approximately 2.5 mm and 10 mm. Each lenslet 120 can have an area between approximately 0.5 mm² and 3.14 mm², although other areas (larger or smaller) can be used in certain embodiments. The lenslets 120 can cover approximately 20% to 60% of the total surface area of ​​the substrate optic 110, although in different embodiments, the lenslets 120 can cover more or less of the total surface area of ​​the substrate.

[0054] As previously described, the plurality of lenslets 120 may be applied with a corrective power (positive or negative). The tinted layer 130 may be applied to a portion or all of the plurality of lenslets 120. In another exemplary embodiment, only a portion of the plurality of lenslets 120 may be applied with a corrective power. In such an exemplary embodiment, the tinted layer 130 may be applied to lenslets 120 that are applied with a corrective power, lenslets 120 that are not applied with a corrective power, or a combination thereof.

[0055] It should be understood that the tinting layer 130 can be directly applied to the lenslets 120. Thus, one or more lenslets 120 can be tinted. The lenslets 120 can be tinted in various ways, for example, by applying a dye to the lenslets 120 or adding a pigment to the lenslets 120.

[0056] However, in some exemplary embodiments, the tinted layer 130 may be applied directly to the underlying laminate aligned with the lenslets, such that the tinted layer 130 is not applied directly to the lenslets 120 themselves, but rather to the underlying laminate of the lenslets 120. In such exemplary implementations, the tinted layer may not be applied to the base lens 110 or the lenslets 120, but only to the intermediate laminate between the base lens 110 and the lenslets 120. In some exemplary embodiments, the laminate may be applied to the inner surface of the base lens 110, so as not to be in direct contact with the lenslets 120.

[0057] In other exemplary embodiments, the tinted layer 130 may be directly coated on the base lens 110 , for example, by coating a dye on the base lens 110 or by dispersing particles in the material forming the base lens 110 .

[0058] Although the present invention has been described in terms of specific embodiments and applications, those skilled in the art can, based on the present teachings, generate more embodiments and modifications without departing from the spirit of the claimed invention or exceeding the scope of the claimed invention. Therefore, it should be understood that the drawings and descriptions herein are provided by way of example to facilitate understanding of the present invention and should not be construed as limiting the scope of the present invention.
