The light source may be configured to emit light within a specific wavelength range, such as blue light with a wavelength of approximately 470 nanometers. The ophthalmic lens may include one or more light guide elements to direct the light emitted from the light source to a desired area of ​​the eye (e.g., the outer region of the retina). The light source may be attached to or integrated with the ophthalmic lens. One or more light guide elements may be configured to reflect, diffuse, disperse, defocus, and / or diffract the light from the light source towards the eye. A control unit may supply power to the light source and be able to program various functions of the light source.

Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the priority and benefit of U.S. Patent Application Serial Number 63 / 498,655, filed on April 27, 2023, entitled "Luminescent Ophthalmic Lens", and the entire disclosure of that application is incorporated herein by reference.

Background Art

[0002] Ophthalmic phototherapy using light of a specific wavelength is commonly used to treat a wide range of conditions in patients. For example, blue light therapy has been found useful in treating conditions such as depression and seasonal affective disorder (SAD), and in some cases has been shown to potentially improve cognitive function.

[0003] Ophthalmic phototherapy devices can be useful in addressing many other problems such as circadian rhythm disorders, jet lag, sleep disorders, shift work disorders, premenstrual syndrome, late luteal phase dysphoric disorder (LLPDD), bulimia and eating disorders, chronic fatigue, migraines, or retinal conditions including retinopathy and retinal vein occlusion. Additionally, it may help in promoting the repair and healing of eye tissues and treating eye injuries by reducing inflammation and improving blood flow.

[0004] Generally, such ophthalmic phototherapy may rely on a handheld or desk - mounted light source that can be bulky or fixed in one place. Such handheld or desk - mounted light sources have various drawbacks, such as potentially restricting the patient's freedom of movement. Other ophthalmic phototherapy systems may instead passively filter a particular wavelength by using a filter that allows the desired wavelength to pass through without being impeded while reducing the transmission of unwanted wavelengths.

[0005] Considering the above, it is desirable to provide ophthalmic phototherapy systems and methods that are active rather than passive, less bulky, portable, and / or do not restrict the free movement of the patient or wearer. [Overview of the project]

[0089] Specific embodiments of the invention are described below with reference to the accompanying drawings. However, the present invention may be embodied in a variety of forms and should not be limited to the embodiments described herein. Rather, these embodiments are provided to make this disclosure complete and comprehensive, and to allow those skilled in the art to fully understand the scope of the invention. The terms used in the detailed description of the accompanying drawings are not intended to limit the invention. In the drawings, the same number refers to the same element.

[0090] For the purposes of this specification, when the terms “about,” “around,” or “approximately” are used when referring to values, it can be implicitly understood that they mean a range of ±5% of the stated value.

[0091] Disclosed herein are various embodiments of light-emitting ocular lenses that may be used, for example, to provide blue light therapy to a patient's eye. The lens may include a light source and one or more light-guiding elements that, when worn, function to reflect, diffuse, defocus, disperse, and / or diffract light to cause light to enter or enter the eye. Alternatively, the lens may include a light source that emits light directly into the eye.

[0092] Ophthalmic lenses may be composed of various lens materials known in the art, including but not limited to polycarbonate, glass, plastic, and Trivex, and may include but not limited to polycarbonate, polyethylene terephthalate (PET), or triacetate cellulose (TAC) laminates. Ophthalmic lenses may be formed using various methods known in the art for lens formation, including but not limited to injection molding or casting.

[0093] Various types of light sources may be used in light-emitting eye lenses. For example, without limitation, such light sources may include various light emitters such as light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), polymer light-emitting diodes (PLEDs), nanoparticles, light-emitting semiconductor nanocrystal materials, and lasers.

[0094] In different embodiments, various wavelengths of light may be emitted by the light source. For example, the wavelength of light emitted by the light source may be any wavelength or any wavelength range within the visible light spectrum, for example, between about 380 nanometers and about 750 nanometers, but not limited to these. In one example, the light source may be configured to emit blue light having wavelengths between about 450 nanometers and about 495 nanometers, or more specifically between about 460 nanometers and about 480 nanometers. In a particular example, the light source may be configured to emit blue light at about 470 nanometers within a deviation of less than 1% of the spectrum.

[0095] Blue light at approximately 470 nanometers has been shown to be crucial for setting circadian rhythms and ocular physiology, and it is also known that in some situations, blue light with wavelengths below 460 nanometers may be problematic for eye health. The exemplary benefits of using blue light in ophthalmic phototherapy described and shown in U.S. Patent No. 9,138,595 are incorporated herein by reference in their entirety. In other examples, the benefits of targeted ophthalmic phototherapy using blue light may include, for example, the reduction of depressive and anxiety symptoms by stimulating serotonin production, and the regulation of the sleep-wake cycle by promoting wakefulness and suppressing melatonin at specific times of the day.

[0096] In further examples, the light source may be configured to emit red light having wavelengths between approximately 620 nanometers and approximately 750 nanometers, for example, for various health or therapeutic purposes, but not limited to these. In more specific examples, the light source may be configured to emit red light at approximately 640 nanometers or approximately 680 nanometers with a variation of less than 1% of the spectrum. The benefits of targeted ophthalmic phototherapy using red light include purposes known to those skilled in the art, such as protecting vision over time and assisting in the recovery of disorders such as macular degeneration or glaucoma, diabetic retinopathy and retinal vein occlusion, as well as promoting healing for various eye injuries by improving blood flow and reducing or suppressing inflammation. Red light ophthalmic therapy may help improve intraocular color contrast sensitivity and rod sensitivity, and therefore may help in perceiving brighter colors or improving vision in low-light environments.

[0097] In further examples, the light source may be configured to emit green light between, for example, approximately 510 nanometers and approximately 570 nanometers, but not limited thereto. In one particular example, the light source may be configured to emit green light at 520 nanometers or 550 nanometers with a variation of approximately 1% of the spectrum. The benefits of targeted ophthalmic phototherapy using green light include purposes known to those skilled in the art, and may include, for example, reducing the severity and frequency of migraines, improving various symptoms associated with neuropathic or chronic pain, and reducing or alleviating symptoms of depression and anxiety by inducing a sedative and relaxing effect on the nervous system, or improving sleep ability.

[0098] In additional examples, the light source may be configured to emit yellow light, for example, between approximately 570 nanometers and approximately 590 nanometers, but not limited thereto. In one particular example, the light source may be configured to emit yellow light at 580 nanometers with a variation of approximately 1% of the spectrum. The benefits of targeted ophthalmic phototherapy using yellow light may be used for purposes known to those skilled in the art, and may include, for example, promoting relaxation and improving sleep quality by stimulating melatonin production, helping to alleviate neuropathic or chronic pain, and promoting healing for various eye injuries by reducing or suppressing inflammation. In further examples, the light source may emit light containing two or more different color combinations to help enhance the effectiveness of certain treatments or treatment plans. Light-emitting ophthalmic lenses may rely on direct light, where the light source is oriented to directly illuminate one or more parts of the eye, or indirect light, where the light source is oriented to directly illuminate one or more light-guiding or light-scattering elements, which then reflect, diffuse, defocus, disperse, and / or diffract the light to one or more parts of the eye. Therefore, the light source may be attached to the outer surface of the ophthalmic lens, or directly incorporated into or integrated with the lens body. In other examples, the light source may be fully or partially attached or embedded within a device external to the lens, such as, but not limited to, an eyeglass frame capable of receiving or holding one or more light-emitting ophthalmic lenses.

[0099] Light sources may be mounted directly or indirectly on the outer surface of an ophthalmic lens. As a first example, the light source may be mounted on the periphery of the lens, either entirely outside the lens or at least partially integrated into its outer edge. As a second example, the light source may be mounted on the inner surface of the lens, in which case light is radiated directly into the eye without the use of a light guide. As a third example, the light source may be mounted on the outer surface of the lens, in which case light guidance may occur through the transmission of light by the lens material itself. However, light transmission may be affected by any laminates used on the lens, or any adhesives used to fix such laminates to the lens. As a fourth example, the light source may be directly integrated or incorporated into the body of the lens itself. Such a configuration may allow light guidance to occur through the lens material while bypassing any laminates and / or adhesives.

[0100] When a light source is oriented or positioned for indirect light application, one or more light guide elements may be formed within or attached to the lens to help reflect, diffuse, disperse, defocus, scatter, and / or diffract the light into or towards the eye. Such light guide elements may include, for example, the use of different refractive indices incorporated into a laminate, microlenses, apertures such as recesses, and laser ablation of parts of the lens.

[0101] When a light source is oriented or positioned for direct light application, the light source may be directly incorporated into or integrated with the lens. In one example, light-emitting semiconductor nanocrystals may be incorporated into or integrated with the lens to direct light toward or into the eye. In another example, light-emitting nanoparticles or microparticles may be incorporated into or integrated with the lens to direct light toward or into the eye.

[0102] Considering all of the above, it is understood that different colors or wavelengths of light, or combinations thereof, may be helpful in treating various eye diseases or health problems. These problems may require different treatment plans, which may vary in light color, light intensity, treatment duration, or treatment frequency, and it is further understood that individual physical configurations and responses to phototherapy vary greatly, requiring individual adjustments. Therefore, it is important that light sources and their control systems may be configured to allow for customization and adjustment of these factors.

[0103] In this regard, the way in which the light source is powered and / or programmed may vary. A control system, including a programmable controller, may allow adjustment of the power level or brightness of the light source as needed. As understood, this may allow the user to select or change the intensity or color of the light provided by the light source for various reasons, such as to correspond to or conform to a treatment plan, whether recommended or self-generated, that helps improve the user's comfort. The control system may also include an on / off switch and a power source, such as a battery, for starting or stopping the light source. The control system may further include a programmable timer so that the light source can be started or stopped in preset cycles. The control system may include memory for storing various operating parameters or programs. The control system may further include a monitor or sensor, and the readings of the monitor or sensor may be stored in memory.

[0104] Specific exemplary embodiments are described in detail below. However, it should be understood that any features from any of the embodiments may be mixed and coincide with each other in any combination. Therefore, the present invention should not be limited to these embodiments, but should be understood to extend to any broader combination thereof.

[0105] Figure 1 is a side view of an exemplary embodiment of a light-emitting eye lens 100. As shown in Figure 1, one example of a light-emitting eye lens 100 may include an eye lens 110 having an outer surface 110A facing outward from the eye 200 and an eye lens having an inner surface 110B facing the eye 200. The light source 120 may be mounted on or near the outer edge of the eye lens 110. The light source 120 may be entirely outside the eye lens 110, entirely inside the eye lens 110, or partially outside and partially inside the eye lens 110. In further examples, the light source 120 may be fixed to the outer surface 110A, the inner surface 110B or otherwise mounted.

[0106] One or more light guide elements 130 may be integrated within the body of the ocular lens 110 and arranged to guide light from the light source 120 to one or more desired locations on the eye 200. Desired locations include, but are not limited to, the outer region of the retina, the inner or central region of the retina, or substantial or complete surface areas of the eye 200 or its entire retina.

[0107] Referring further to Figure 1, it can be seen that one or more light guide elements 130 may be incorporated into the body of the ophthalmic lens 110 itself. While Figure 1 shows that one or more light guide elements 130 may include multiple light guide elements, it should be understood that one or more light guide elements 130 may include only a single light guide element in some exemplary embodiments. Furthermore, the number, positioning, and orientation of one or more light guide elements 130 shown in the exemplary embodiments shown in Figure 1 should not be construed as limiting its range, and the number, positioning, and orientation of one or more light guide elements 130 may vary in different embodiments and may be adapted to different examples of ophthalmic lenses 110 with different structures or intended uses.

[0108] In some such examples, one or more light guide elements 130 may be dispersed, clustered, or positioned in one or more predefined regions within the ophthalmic lens 110, with each particle functioning as a light guide or light guide tube. In other examples, one or more light guide elements 130 may be uniformly or non-uniformly dispersed across a partial surface region or the entire surface region of the ophthalmic lens 110. In such examples, each of the one or more light guide elements 30 may be a scattering particle, such as, but not limited to, micro or nanoparticles, that functions as a light scattering or deflection center rather than a light guide.

[0109] In any of the examples described above or below in this disclosure, one or more light guide elements 130 may include, for example, between about one light guide element and about ten light guide elements, between about eleven light guide elements and about 100 light guide elements, or between about 100 and about 1000 light guide elements, or even more than a number of light guide elements or scattering elements.

[0110] Referring further to Figure 1, one or more light guide elements 130 may include one or more laminates 125 manufactured on the eye lens 110 in different regions. These regions may be configured to reflect and diffuse light from the light source 120 to the eye 200. For example, one or more laminates 125 may be patterned with reflective surfaces using grid-like or lattice-like barriers to reflect light from the light source 120 to the eye 200, as shown in Figure 1. In further examples, one or more laminates 125 may be patterned with other types or shapes of reflective elements or reflective surfaces, such as random or repeating patterns, configured to reflect, diffuse, scatter, or otherwise redirect light from the light source 120 to the eye 200.

[0111] Figure 2 is a side view of an exemplary embodiment of a light-emitting eye lens 100. As shown in Figure 2, one example of a light-emitting eye lens 100 is an embodiment in which one or more light-guiding elements 130 are formed on an eye lens 110, or are composed of, but are not limited to, a plurality of points formed on the eye lens 110, or include such elements. In such an embodiment, the light source 120 may be attached to the outer edge of the eye lens 110, or be fully or partially integrated, as shown in Figure 2. Such laser ablation may be performed in an array pattern or other arrangement, either of which disperses, diffuses, or deflects light from the light source 120 to the eye 200, thereby allowing the wearer of the eye lens 110 to see the light. In one exemplary embodiment, the lens material functions like an optical pipe, and the voids or changes in refractive index formed by the laser ablation can cause reflection, dispersion, or deflection of light. Exemplary lenses incorporating different refractive regions are shown and described in U.S. Patent No. 11,029,540, which is incorporated herein by reference.

[0112] It should be understood that the position of the light source 120 along the outer periphery, edge, or rim of the ophthalmic lens 110 may vary in different embodiments and should not be limited by the exemplary embodiments shown in the figures. Therefore, while the figures show that the light source 120 may be positioned near the upper edge or top of the ophthalmic lens 110, it should be understood that the light source 120 may alternatively be positioned near the lower edge or bottom of the ophthalmic lens 110, or at any other position along the outer periphery.

[0113] Figure 3 shows a side view and a magnified view of an exemplary embodiment of the luminescent eye lens 100. As shown in Figure 3, one example of the luminescent eye lens 100 may be an embodiment that includes a light source 120 which may be used for direct or indirect illumination of the eye 200. In the exemplary embodiment shown in Figure 3, it is recognized that the light source 120 may be realized as a plurality of light-emitting semiconductor nanocrystals incorporated into the viewing path of the eye lens 110 or otherwise integrated. However, it should be understood that in some embodiments, such light-emitting semiconductor nanocrystals of the light source 120 may be used for indirect illumination in combination with one or more light guide elements 130.

[0114] Examples of luminescent nanocrystal materials are shown and described in U.S. Patent No. 8,080,437, which is incorporated herein by reference in its entirety. In such examples, the light source 120 may be entirely or partially formed of a number of luminescent semiconductor nanocrystals ranging from about one to about ten, from about eleven to about 100, or from about 100 to about 1000, or even more. Furthermore, the luminescent semiconductor nanocrystals of the light source 120 may be arranged, positioned, or grouped in any manner described above or below with respect to one or more light guide elements 130, for example, at any location within one or more laminates 125, or at any location within other material layers of the eye lens 110, but not limited to those locations.

[0115] Referring further to Figure 3, it can be seen that one or more laminates 125 may be a conductive transparent film that is fixed to or may be fixed within the ophthalmic lens 110. For example, an optical-grade adhesive or one or more light-emitting semiconductor nanocrystals of the light source 120 fixed at a position for direct or indirect application of light emitted to the eye 200. A power connector 150 may be incorporated into the ophthalmic lens 110 and may be electrically connected to one or more light-emitting semiconductor nanocrystals of the light source 120 for power supply purposes. As an example, the power connector 150 may include a direct current ("DC") power connector.

[0116] Figure 4 is a side view of an exemplary embodiment of the light-emitting eye lens 100. As shown in Figure 4, one example of the light-emitting eye lens 100 may be an embodiment in which a light source 120 is attached to or integrated with the eye lens 110, and light emitted from the light source 120 is directed to one or more light guide elements 130. One or more light guide elements 130 may consist of one or more microlenses, miniature lenses, or multiple segmented focus integrations ("DIMS"). Examples of such microlenses are shown and described in U.S. Patents 10,386,654 and 11,131,869, both of which are incorporated herein by reference in their entirety.

[0117] The use of such microlenses may offer a dual function: providing phototherapy from a light source, treating myopia, hyperopia, or helping to slow or improve the progression of other types of refractive errors. For example, a microlens may be designed to correct peripheral misfocus, thereby potentially slowing the progression of myopia or other types of refractive errors. In another example, a microlens with peripheral positive power (peripheral hyperopia) may help slow the progression of myopia or other types of refractive errors. In yet another example, a microlens may help adjust the eye's focusing ability by controlling accommodation (e.g., the eye's ability to focus on objects at different distances), and such a microlens may help manage the progression of myopia or other types of refractive errors.

[0118] Referring further to Figure 4, it can be seen that one or more light guide elements 130 may be positioned toward the eye on or near the inner surface 110B of the ophthalmic lens 110. However, it should be understood that one or more light guide elements 130, such as microlenses, shown in Figure 4, may be positioned at various other locations along or within the ophthalmic lens 110. In any of the exemplary ophthalmic lenses 110 shown in Figures 1-4, the inner surface 110B may be part of the first lens layer of the ophthalmic lens 110, and the outer surface 110A may be part of the second lens layer of the ophthalmic lens 110.

[0119] In some such examples, each of these first and second lens layers may be a single polycarbonate layer. In other examples, each of these first and second lens layers may consist of multiple layers of similar or different materials. Such materials may include, but are not limited to, polycarbonate sheets or polycarbonate laminates, glass sheets or glass laminates, nylon sheets or nylon laminates, polyimide sheets or polyimide laminates, polyethylene terephthalate ("PET") sheets or PET laminates, biaxially oriented PET triacetate laminates, or any other non-polarizing or polarizing sheet laminates.

[0120] Furthermore, in any of the above examples, such laminate sheets, or other components such as one or more laminates 125, microlenses, miniature lenses, defocus-integrated multi-segments, or luminescent nanocrystals, may be bonded to each other using various optical adhesives. In one example, a polyurethane adhesive manufactured by reacting V03 and V04 may be used. In other examples, pressure-sensitive adhesives, humidity-curing adhesives, or ultraviolet light or electron beam-curing adhesives may be used. In one particular example, 3M8213OCA adhesive, which can be cured at approximately 80 degrees Fahrenheit, may be used. Other non-limiting examples may include 3M8146-2OCA and 3M CEF 3104AS OCA, which are cured by the application of pressure.

[0121] In some examples, the total thickness of the light-emitting eye lens 100 may be between approximately 10 millimeters and approximately 40 millimeters. In one example, the first lens layer, which may form the inner surface 110B, may have a thickness of approximately 12 millimeters or approximately 15 millimeters, and the second lens layer, which may form the outer surface 110A, may each have a thickness of approximately 15 millimeters or approximately 12 millimeters. Figure 5 is a block diagram showing a control unit 160 of the light-emitting eye lens 100 according to an exemplary embodiment. As shown in Figure 5, one example of the control unit 160 may be an embodiment in which the control unit 160 provides several functions, including but not limited to supplying power to the light source 120, programming the light source 120, saving or executing operating parameters, sensing or monitoring the light source 120, etc.

[0122] As shown in Figure 5, the control unit 160 may include a power supply 162, a programmable data processor 164, a timer 166, an external display or monitor 168, memory 170, and / or monitor / sensor 172, and perform a wide range of functions. The control unit 160 may be integrated into the ophthalmic lens 110, or remain outside the ophthalmic lens 110, and may be electrically connected to the light source 120, or otherwise electrically connected. In one example, the control unit 160 may be fully or partially integrated into the eyeglass frame 111 (Figure 9). The power supply 162 may be rechargeable. For example, the light source 120 requires a power consumption of approximately 0.384 mA / h, and daily charging may provide approximately 0.864 mA / h for 60 minutes of therapeutic operation per day, taking into account losses in the electronics of the light-emitting diode ("LED") lighting.

[0123] With the above in mind, the control unit 160 may be a control system that allows a user to program, control, or adjust various output modes of the light source 120 as needed, for example, via one or more user inputs to a programmable data processor 164, the various output modes of the light source 120 including, in particular, the light power level (e.g., brightness or intensity of light), the color of light (e.g., wavelength), or the duration or length of light emission from the light source 120. In some examples, such user inputs may be input / output ("I / O") devices of the control unit 160, such as, but not limited to, an external display or monitor 168. In other examples, the I / O device may be a button, switch, or other feature of the programmable data processor 164, the power supply 162, or other components of the control unit 160. In some examples, at least one I / O device may be positioned on the spectacle frame 111 shown in Figure 9, for example, allowing a user to, in particular, turn the power supply 162 on or off, or adjust other output modes of the light source 120.

[0124] In further examples, the output mode of the light source 120 may be customized via other user input means, such as via a wireless connection to the control unit 160. In some such examples, it is understood that the control unit 160 may be configured to send and receive program or data instructions over a wireless communication network using a transmission medium, such as via the network interface device of the control unit 160. The transmission and reception may utilize one of several transmission protocols, including but not limited to Frame Relay, Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), NFC Forum Handover Protocol (NHP), NFC Data Interchange Protocol (NDP), or other protocols. Examples of wireless communication networks include local area networks (LANs), wide area networks (WANs), packet data networks (e.g., the Internet), mobile phone networks (e.g., cellular networks), wireless data networks (e.g., the IEEE 802.11 family of standards known as WiFi®, the IEEE 802.16 family of standards known as WiMAX®), the IEEE 802.15.4 family of standards, and peer-to-peer (P2P) networks.

[0125] In an additional example, the control unit 160 may be configured to send and receive program or data instructions via wired means, such as through a wired connection established via one or more computer data ports (e.g., USB, SATA, etc.) of the control unit 160.

[0126] Figure 6 is a front view of an exemplary embodiment of the light-emitting eye lens 100. As shown in Figure 6, one example of the light-emitting eye lens 100 may be an embodiment in which a light source 120 is incorporated into the body of the eye lens 110, for example by embedding or lamination, to directly illuminate the eye. Furthermore, one or more active light-emitting components included in the light source 120 may be arranged in accordance with the embodiments described above or below with respect to one or more light guide elements 130, for example, at any position in one or more laminates 125, or at any position in other material layers of the eye lens 110.

[0127] Although not shown, in various embodiments, when the light source 120 is incorporated into the eye lens 110, leads such as copper wires may be used to connect the light source 120 to an external or attached power source. Such electrical leads may be secured with tape or by other means to various parts of the eye lens 110, such as the edge of the eye lens 110. Incorporating the light source 120 into the eye lens 110 may be useful for applications that directly illuminate the eye 200.

[0128] The positioning of the light source 120 may vary when embedded within the ophthalmic lens 110. For example, the light source 120 may be embedded on or near the outer surface 110A, on or near the inner surface 110B, or within the internal body or central region of the ophthalmic lens 110. When embedded within the ophthalmic lens 110, the positioning of the light source 120 may affect whether or not light guidance occurs and whether it is effective. Furthermore, the positioning of the light source 120 in relation to the eye 200 may vary depending on the ophthalmic treatment performed and other considerations. For example, the light source 120 may be embedded in the outer region of the retina of the eye 200, or alternatively, in a position to direct light toward the inner or central region (Figures 1-4).

[0129] More specifically, if a more intensive treatment or a more efficient optical path to the eye 200 is desired, one or more light guide elements 130 or light sources 120 as described above or below may be configured to direct (e.g., radiate) or indirectly (e.g., reflect or redirect) light toward the outer region of the eye 200 (e.g., the peripheral retina), where rod cells are dominant and the eye 200 may be more sensitive to changes in light intensity. Alternatively, if a lower intensity treatment or a less efficient optical path to the eye 200 is desired, one or more light guide elements 130 or light sources 120 as described above or below may be configured to direct (e.g., radiate) or indirectly (e.g., reflect or redirect) light toward the inner or central region of the eye 200 (e.g., the macula and fovea), where cone cells are dominant and the eye 200 may be relatively less sensitive to light intensity.

[0130] Figures 7A to 7C are front views of the luminescent eye lens 100 according to exemplary embodiments, which will be described below. As shown in Figures 7A to 7C, an example of the luminescent eye lens 100 is an embodiment in which a light source 120 is fixed to the outer edge of the eye lens 110, or is fully or partially incorporated, and one or more light guide elements 130 may consist of small lens dips formed directly on the lens to reflect and diffuse light from the light source 120 to the eye 200 (Figures 1 to 4).

[0131] Such configurations may be considered the inverse of the microlens configurations shown earlier in Figure 4 and described in relation thereto. In some examples, the small recesses forming one or more light guide elements 130 may have a diameter of about 1 millimeter and a depth of less than 0.1 millimeters. In some examples, the injection-molded lens 100 may have a hole formed at the central end of the lens 100 that is about 3 millimeters in diameter and about 4 millimeters deep. As shown in Figure 7A, in some examples, one or more light guide elements 130 may be positioned or grouped near the center or inner region of the ophthalmic lens 110 to guide light only to the central or inner region of the eye 200 (e.g., the macula and fovea), or mainly to the central or inner region (e.g., the macula and fovea) (Figures 1-4). In such examples, it should be understood that the central or inner region of the ophthalmic lens 110 may be defined as being closer to its center point than to the periphery of the ophthalmic lens 110.

[0132] In another example, as shown in Figure 7B, one or more light guide elements 130 may be positioned or grouped near the outer region of the ophthalmic lens 110 to guide light only to the outer region of the eye 200 (e.g., the peripheral retina), or primarily to the outer region (e.g., the peripheral retina). In some examples, as also shown in Figure 7B, one or more light guide elements 130 may be positioned to define two or more separate groups, or predefined regions, each containing a different number of individual light guide elements. In one such example, each of the one or more groups may be positioned closer to the edge of the ophthalmic lens 110 than to the center of the ophthalmic lens 110, as shown in Figure 7B.

[0133] In additional examples, as shown in Figure 7C, one or more light guide elements 130 may be distributed entirely or substantially across the entire surface area of ​​the ophthalmic lens 110. In such examples, one or more light guide elements 130 may be distributed uniformly or non-uniformly (e.g., randomly), and may also be grouped, for example, into one, two, three, four, five, six, or more individual groups, or to define predefined areas each containing one or more light guide elements 130. The lens dip patterns and positioning shown in Figures 7A-C are for illustrative purposes only and should not be interpreted as limiting the scope.

[0134] Figure 8 is a graph showing the absolute irradiance as a function of wavelength based on different positioning of one or more light guide elements 130 and / or light sources 120. Optimal values ​​may include approximately 1 microwatt per square centimeter per nanometer. As previously mentioned, the positioning of the light source 120 (Figures 1-4, 6-7, 9) and one or more light guide elements 130 (Figures 1-4, 6-7, 9) may affect the direction of light or the efficiency of light guidance from the eye lens 110 (Figures 1-4, 6-7, 9) to the eye 200 (Figures 1-4).

[0135] In the example shown in Figure 8, represented by lines L1 to L8, the light source 120 is at least partially inserted into the ophthalmic lens 110 near the inner surface 110B and extends at least partially to the outer edge or end of the ophthalmic lens 110.

[0136] Line L1 represents the absolute irradiance value observed from the eye lens 110 when one or more light guide elements 130 are located on the inner surface 110B and positioned at the center point or central region of the eye lens 110.

[0137] Line L2 represents the absolute irradiance value observed from the eye lens 110 when one or more light guide elements 130 are located on the outer surface 110A and positioned at the center point or central region of the eye lens 110.

[0138] Line L3 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are located on the inner surface 110B and positioned in the inner region of the ophthalmic lens 110.

[0139] Line L4 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are located on the outer surface 110A and positioned within an inner region offset from the center point of the ophthalmic lens 110. Such an inner region may generally be defined as a lateral offset from the center point that is closer to the center point than the outer edge or end of the ophthalmic lens 110, and may include, for example, an offset range of about 2 millimeters to about 10 millimeters from the center point or central region.

[0140] Line L5 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are inserted into the ophthalmic lens 110 at a position approximately 10 millimeters from the inner surface 110B and are positioned at the center point or central region of the ophthalmic lens 110.

[0141] Line L6 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are inserted into the ophthalmic lens 110 at a position approximately 10 millimeters from the outer surface 110A and are positioned at the center point or central region of the ophthalmic lens 110.

[0142] Line L7 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are inserted into the ophthalmic lens 110 at a position approximately 10 millimeters from the inner surface 110B and are positioned within an inner region offset from the center point of the ophthalmic lens 110.

[0143] Line L8 represents the absolute irradiance value observed from the ophthalmic lens 110 when one or more light guide elements 130 are inserted into the ophthalmic lens 110 at a position approximately 10 millimeters from the outer surface 110A and positioned within an inner region offset from the center point of the ophthalmic lens 110. Such an inner region may generally be defined as a lateral offset from the center point that is closer to the center point than the outer edge or end of the ophthalmic lens 110, and may include, for example, an offset range of approximately 2 millimeters to approximately 10 millimeters from the center point or central region.

[0144] Figure 9 is a front view of a frame 111 including a pair of light-emitting eye lenses 110 according to an exemplary embodiment. Each of the pair of light-emitting eye lenses 110 may represent an example or embodiment of the light-emitting eye lens 100 described above or below. In some examples, the frame 111 may support only a single lens 110.

[0145] Furthermore, each lens 110 of a pair of luminescent eye lenses 110 may be similar or different from one another, for example, depending on the needs of an individual patient. In one example, each of the pair of luminescent eye lenses 110 may differ from one another by including differently configured microlenses or by being molded or formed to impart different corrective forces, which may include, for example, a power ("PWR") indicating a positive or negative number indicating the degree of correction to improve near and / or distance visual acuity, a cylindrical power ("CYL") indicating a positive or negative number to address astigmatism, an axis ("AX") indicating the axial direction of astigmatism, an add power ("ADD"), a monofocal near ("SVN"), or a monofocal far ("SVD"), and may be formed using any lens-forming process known in the art.

[0146] In another example, one of the lenses 110 may include a light guide element 130, while another lens 110 may not include a light guide element 130. In yet another example, one of the lenses 110 may include a first type of light guide element 130, while another lens 110 may include a second type of light guide element 130 that is different from the first type of light guide element 130.

[0147] As shown in Figure 9, one example of the light source 120 may be an embodiment in which the light source 120 is partially integrated into or embedded in the eyeglass frame 111. In such an example, it is understood that the light source 120 may include one or more light-emitting components for each of the pair of light-emitting eye lenses 110, each of which may include the previously described examples of the light source 120. In some examples, a single light source 120 may emit light toward both lenses 110. In other examples, each lens 110 may have its own dedicated light source 120.

[0148] In some examples, the light source 120 may be mounted on the frame 111 or embedded within the frame 111. In some examples, the light source 120 may be configured to extend to each of the rims 115 of the frame 111 and from there toward each of the pair of eye lenses 110 or into the eye lenses 110. In some examples, if the light source 120 is embedded within the frame 111, it may be positioned to be flush with or fitted inward with respect to the outer surface of the frame 111.

[0149] In some examples, the light source 120 may be positioned entirely or entirely within the arm, bridge, or any other part of the eyeglass frame 111. In further examples, the light source 120 may be entirely external to the eyeglass frame 111 and mounted thereto to radiate light toward the pair of eye lenses 110. In yet another example, the light source 120 may be entirely external to both the pair of eye lenses 110 and the eyeglass frame 111 and remotely positioned and mounted, for example, on a hat, headband, neckband, shirt, or any other clothing or device that can be used to hold the light source 120 and / or the eye lenses 110 or the pair of eye lenses 110. In some examples, the light source 120 may be attached directly to the user, for example, by adhesive.
