Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens technology, specifically to a multi-effect optical lens. Background Technology
[0002] Myopia control lenses utilize special optical designs to alter the optical signals of peripheral light, thereby influencing retinal growth signals and slowing down axial elongation. Among related technologies, myopia control lenses are primarily developed based on DOT, DIMS, and DISC technologies. DOT lenses are developed based on the theory of retinal contrast signals, meaning that low-contrast optical signals easily inhibit axial elongation. DISC is a soft corneal contact technology, commonly used in contact lens products. DIMS is a myopia control lens based on peripheral defocus theory. Both DIMS and DISC lenses rely on defocus control, that is, inhibiting axial elongation by projecting optical signals that are not on the retinal surface.
[0003] However, due to the differences in the distribution characteristics of visual function cells in the fundus of different populations, most of the myopia control lenses in the current technology can only generate a specific optical signal. Different populations have different sensitivities to various types of optical signal stimulation, so the universality of myopia control lenses is insufficient. Moreover, due to the elongation of the axial length of myopic patients, the fundus is stretched and thinned by the axial length, and the distribution of visual function cells in the fundus changes. Existing myopia control lenses are difficult to target and regulate this distribution.
[0004] Based on this, this application proposes a multi-effect optical lens in order to solve at least one of the aforementioned problems. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0036] This application provides a multi-effect optical lens, which solves the problems of single optical signal and insufficient universality of existing myopia control lenses.
[0037] The technical solution in this application is to solve the aforementioned technical problems, and the overall approach is as follows:
[0038] Myopia control lenses, through special optical design, alter the optical signals of peripheral light, thereby affecting retinal growth signals and slowing down axial elongation. However, due to differences in the distribution characteristics of visual function cells in the fundus among different populations, and variations in the sensitivity of different populations to various types of optical signal stimuli, existing myopia control lenses, whether employing multiple scattering structures to adjust the contrast of optical signals to affect the retina or using microlenses to change the imaging position (defocus signal) to affect the retina, typically offer a relatively limited range of optical signals. These lenses can only be suitable for a small number of specific populations, lacking universality and failing to be tailored to the distribution of visual function cells in the fundus of myopic individuals.
[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0040] Example 1:
[0041] See Figures 1-6 As shown, a multi-effect optical lens includes a lens body 1, and further includes: a first optical region 2, which is composed of multiple optical devices with scattering function; a second optical region 3, which is composed of multiple optical devices with refractive power; and a third optical region 4, which is composed of multiple continuous cylindrical lens structures; the first optical region 2, the second optical region 3, and the third optical region 4 are all disposed on the lens body 1; the first optical region 2, the second optical region 3, and the third optical region 4 partially overlap within the surface area of the lens body 1.
[0042] In this embodiment, it should be noted that, firstly, the first optical area 2 is composed of multiple optical devices with scattering function. On the one hand, scattering can make the light evenly distributed, so that the originally concentrated light is dispersed in all directions, reducing the contrast and thus inhibiting the elongation of the axial length. On the other hand, since the axial length of myopic patients is elongated, the fundus is stretched, which leads to the thinning of the fundus and the sparse distribution of peripheral photoreceptor cells. After scattering, the light changes from a single parallel beam to a multifocal divergent beam, and its energy distribution diffuses to the periphery, thereby adapting to the sparsely distributed peripheral photoreceptor cells of myopic people and enhancing the reception efficiency of optical signals.
[0043] Secondly, the second optical zone 3 is composed of multiple optical devices with refractive power, such as defocused lenses with refractive power, or other materials with different refractive indices set on the lens body 1. For myopic patients, myopia is caused by an excessively long anteroposterior diameter of the eyeball or an excessively steep corneal curvature, which causes external light to focus in front of the retina instead of falling directly on the retina, resulting in blurred vision. Optical devices with refractive power can cause incident light to be refracted and focused in front of the retina, forming a diffuse defocused spot (i.e., a defocused signal). This spot stimulates peripheral visual cells, slows down the growth of the axial length of the eye, and thus controls the development of myopia.
[0044] Furthermore, the third optical zone 4 is composed of multiple continuous cylindrical lens structures. Optical devices with cylindrical lenses can achieve myopia control by correcting astigmatism and regulating directional defocus signals. The principle is as follows: Cylinders utilize their characteristic of different refractive power in different directions. On the one hand, they can correct the blurred retinal imaging caused by astigmatism and eliminate the cause of axial elongation caused by aberrations. On the other hand, by cooperating with other optical signals (such as the scattering signals and / or defocus signals mentioned above), they can make light from specific directions act on the visual cells in areas with more significant axial elongation (such as the temporal retinal traction area), thereby achieving optical signal regulation of specific retinal areas and adapting to the distribution characteristics of visual function cells in the fundus traction that may exist in myopic individuals.
[0045] The embodiments of this application, through the overlapping arrangement of the first optical zone 2, the second optical zone 3 and the third optical zone 4, can provide multiple optical signal stimulations to the eyes of myopic patients, thereby improving the myopia prevention and control effect.
[0046] Example 2:
[0047] See Figures 1-6 As shown, the present application provides a multi-effect optical lens, including all the contents of Embodiment 1 and its preferred embodiments. In addition, the lens body 1 includes opposing convex and concave surfaces, and the first optical region 2, the second optical region 3 and the third optical region 4 can be independently disposed on the convex and concave surfaces of the lens body 1, respectively.
[0048] In this embodiment, it should be noted that, due to the different myopia conditions of patients, the structural dimensions of various optical devices in the first optical zone 2, the second optical zone 3 and the third optical zone 4 may be different. By setting them independently on the concave and convex surfaces of the lens body 1, the processing difficulty of the lens of this application can be reduced, and adjustments can be made according to the specific myopia condition of the patient.
[0049] In a preferred embodiment, the multi-effect optical lens provided in this application further includes a central optical region 5, which is disposed at the center of the lens body 1, and the first optical region 2, the second optical region 3 and the third optical region 4 are all disposed on the outer periphery of the central optical region 5.
[0050] In this embodiment, it should be noted that the central optical zone 5 corresponds to the patient's macula, and no additional optical equipment is installed in this area to ensure that the wearer's main field of vision is clear.
[0051] Example 3:
[0052] See Figures 1-6 As shown, the present application provides a multi-effect optical lens, including all contents of embodiments 1-2 and their preferred embodiments. In addition, the scattering optical device in the first optical region 2 is a micromirror, which is arranged in a circular radial array on the lens body 1. The spacing between two adjacent micromirrors with the same diameter or at the same distance from the center of the lens body 1 is equal.
[0053] In this embodiment, it should be noted that the circular radial array arrangement of the scattering optical device makes the scattering signal in all directions uniformly distributed, avoiding uneven control effect caused by azimuth differences. Moreover, the regular array layout facilitates lens mold processing and mass production, reduces process complexity, and ensures structural consistency in each area of the lens, thereby improving product stability.
[0054] In a preferred embodiment, the second optical zone 3 consists of multiple optical devices with refractive power, which are defocus lenses, arranged in a circular radial array on the lens body 1. The distance between two adjacent defocus lenses with the same diameter or at the same distance from the center of the lens body 1 is equal.
[0055] In this embodiment, it should be noted that the circular radial array arrangement of the defocus lens ensures that the scattered signals in all directions are evenly distributed, avoiding uneven control effects caused by directional differences. Furthermore, the regular array layout facilitates lens mold processing and mass production, reducing process complexity, while ensuring structural consistency in all areas of the lens and improving product stability.
[0056] In addition, the defocus amount of each defocus lens can be set independently, such as gradually increasing from the center of the field of vision to the outer edge of the field of vision, forming a defocus amount gradient from the center to the periphery; this design can simulate the refractive state of the human eye when it sees objects naturally, so that the defocus amount in the peripheral area increases with distance, gradually enhancing the control effect and alleviating the visual interference caused by the sudden change in defocus amount when the wearer's vision moves from the central optical zone 5 to the second optical zone 3.
[0057] In a further preferred embodiment, the cylindrical lens structure of the third optical zone 4 is arranged in a circular diffusion pattern on the lens.
[0058] In this embodiment, it should be noted that some people may be sensitive to the optical signals generated by a continuous and ring-shaped cylindrical lens structure. This application integrates a scattering structure and a refractive optical structure with an overlapping area, so that some of the optical signals generated by the refractive optical structure of the second scattering structure can be refracted by the cylindrical lens, affecting the wearers who are more sensitive to it, thereby improving the universality of the lens of this application.
[0059] Example 4:
[0060] The present application provides a multi-effect optical lens, including all contents of embodiments 1 to 3 and their preferred embodiments. In addition, the micromirror diameter in the first optical region 2 is 0.01mm to 0.40mm.
[0061] In this embodiment, it should be noted that a smaller scattering structure can avoid energy loss caused by excessive light dispersion, and more scattered optical signals can be arranged on the same lens area, providing a better control effect.
[0062] In a preferred embodiment, the defocus lens in the second optical zone 3 has a diameter of 0.01 mm to 0.40 mm.
[0063] In this embodiment, it should be noted that a smaller defocus lens can arrange more scattered optical signals on the same lens area, providing better control effect; and since the resolution of the human eye is limited, when the light spot produced by the smaller defocus lens is smaller than the minimum resolution of the human eye, it will not cause the human eye to feel blurred, thereby improving the imaging quality of the lens and the user's experience.
[0064] In a further preferred embodiment, the width of the cylindrical lens structure in the third optical region 4 is 0.02~0.40mm.
[0065] In this embodiment, it should be noted that a narrower cylindrical lens structure is beneficial to improving the flexibility and accuracy of astigmatism correction. More refined zoning design can be carried out on the lens. Especially for complex astigmatism cases, the combination of multiple narrow cylindrical lenses can achieve targeted compensation for astigmatism errors in different directions, providing better control effect.
[0066] In summary, compared with existing technologies, it has the following beneficial effects:
[0067] 1. This application, by setting up a first optical zone, a second optical zone, and a third optical zone, can provide multiple optical signal stimulations to the eyes of myopic patients, thereby improving the myopia control effect; by forming scattering and defocusing signals through scattering structures and optical instruments with refractive power, and by alleviating astigmatism through cylindrical lens structures, it can provide multiple optical signal stimulations as close as possible to the high-density visual function cell area near the center of the light spot through the overlap of optical zones, thereby improving the myopia control effect.
[0068] 2. This application sets up a central optical zone that corresponds to the patient's macula. No additional optical equipment is placed in this area to ensure that the wearer's main field of vision is clear. Furthermore, the scattering area formed by the first optical zone is far from the central optical zone, so that a smooth optical transition can be formed between the central optical zone and the second optical zone. This alleviates the visual interference caused by the sudden change in defocus when the wearer's vision moves from the central optical zone to the second optical zone.
[0069] 3. By setting up the scattering structure, refractive structure and cylinder arrangement, this application can make the optical signal distribution in all directions uniform, avoid the uneven control effect caused by directional differences, and the regular array layout facilitates lens mold processing and mass production, reduces process complexity, and at the same time ensures the structural consistency of each area of the lens and improves product stability.
