Description

Technical Field

[0001] This utility model relates to the technical field of lenses, specifically to a defocused light diffusion composite lens. Background Technology

[0002] As we all know, the ciliary muscle controls the size of the pupil and maintains the curvature of the lens. The ciliary muscle itself contracts or relaxes to a certain extent as the eye focuses on near or far objects. When the eye focuses on near objects, the muscle is in a tense state and cannot relax. Prolonged high concentration on near objects can lead to ciliary muscle spasm, which can easily cause myopia.

[0003] Most common myopia lenses are single-vision lenses. Their characteristic is that parallel light rays are refracted by the lens, pass through the central area of ​​the eyeball, and reach the retina to form a clear image, enabling people to see objects clearly. However, because the eyeball is a round body, parallel light rays passing through the top, bottom, and left and right ends of the lens will reach the back of the retina, causing the peripheral areas of the eye to appear similar to presbyopia, resulting in blurred vision. In order to see the surrounding objects clearly, the axial length of the eye is elongated, which deepens the development of myopia.

[0004] In response, industry professionals have improved the structure of myopia lenses and developed various myopia-inhibiting lenses, resulting in numerous related patent applications. However, many technologies still have shortcomings in their effectiveness in inhibiting myopia. The inventor of this invention previously researched and developed "A Myopia Control Lens," patent number ZL202421245753.4, as follows... Figures 1 to 3 As shown, the convex center of the myopia substrate 10 is the convex region A1 for myopia. A defocus region B is set around the convex region A1 for myopia. Protruding circular microlenses B1 are evenly distributed in the defocus region B. The circular microlenses B1 on the myopia substrate 10 have a second refractive power to inhibit the development of myopia. The rest of the myopia substrate 10, except for the circular microlenses B1, has a first refractive power to correct myopia. The concave center of the myopia substrate 10 is the concave region A2 for myopia. A point diffusion region C is set around the concave region A2 for myopia. Concave diffusion points C1 are evenly distributed in the point diffusion region C. Compared to single-vision lenses, this structure achieves the functions of adjusting the ciliary muscle, relieving eye fatigue, reducing contrast, and inhibiting myopia progression. However, it has a drawback: a large number of concave diffusion points C1 on the concave surface of the myopia substrate 10 coincide with the circular microlenses B1 on the convex surface of the myopia substrate 10. The four lines X in the figure indicate the four overlapping positions. As a result, the secondary refractive power of the circular microlenses B1 in the overlapping part is weakened. Due to the variable degree of overlap of each circular microlens B1, its secondary refractive power not only varies but also exhibits unevenness. Consequently, the accommodative relaxation effect on the ciliary muscle is weakened and unstable, thus affecting the myopia control effect.

[0005] In view of this, the inventors continued to conduct in-depth research and developed a defocused light diffusion composite lens, which led to this invention. Utility Model Content

[0006] The purpose of this invention is to provide a defocused light diffusion composite lens to ensure the adjustment effect of the circular microlens in the defocused area on the ciliary muscle, relieve eye fatigue, reduce contrast, and enhance the effect of inhibiting myopia.

[0007] To achieve the above objectives, the solution of this utility model is:

[0008] A defocused light diffusion composite lens comprises a convex region for myopia at the center of the convex surface of a myopia substrate, a defocus region surrounding the convex region, and several raised circular microlenses arranged in the defocus region. The circular microlenses on the myopia substrate possess a secondary refractive power to inhibit the progression of myopia, while the remaining portions of the myopia substrate, excluding the circular microlenses, possess a primary refractive power to correct myopia. An outer reinforcing layer is disposed on the convex surface of the myopia substrate, and an outer OAR film is disposed on the outer reinforcing layer. The tops of the circular microlenses protrude beyond the outer reinforcing layer and the outer OAR film. An inner reinforcing layer is disposed on the concave surface of the myopia substrate, and an inner OAR film is disposed on the inner reinforcing layer. A concave region for myopia is located at the center of the inner OAR film, and a dot diffusion region is disposed around the concave region of the inner OAR film. Several recessed diffusion points are evenly distributed in the dot diffusion region, avoiding the corresponding positions of the circular microlenses, so that the circular microlenses on the convex surface and the diffusion points on the concave surface do not coincide.

[0009] The outer and inner reinforcing layers are both 3-8 μm thick, giving the lens a wear-resistant and scratch-resistant effect.

[0010] The thickness of both the outer OAR film and the inner OAR coating is 90-110nm, which can reduce the reflected light from the back of the lens to the eye, making the vision clearer.

[0011] The circular microlens has a power rating of +2.00D to +6.00D.

[0012] The convex region of the myopic eye is larger than the concave region, while the defocus region is smaller than or equal to the dot diffusion region. Furthermore, the diameter of the convex region of the myopic eye is 7-12 mm, the diameter of the concave region is 5 mm, the diameter of the defocus region is 40-70 mm, and the diameter of the dot diffusion region is 70-76 mm.

[0013] The diameter of each diffusion point is 0.2 mm, and the depth of each diffusion point is 0.1-0.8 mm.

[0014] When the diameter of the defocused area is 44mm, the defocused area consists of 600 circular microlenses arranged in a certain regular pattern. Starting from the outer edge of the convex area of ​​the myopic eye, 24 main spokes radiate outwards evenly from the defocused area. Each main spoke has 12 gradually increasing circular microlenses, spreading out to form 12 main rings. The smallest circular microlenses on each main spoke form the first main ring, which contains 24 microlenses. Each main ring has the same number of microlenses, for a total of 288 microlenses. The distance from the optical center of the lens to the center of the smallest circular microlens on the main spoke is 3.9mm. The distance from the optical center of the lens to the center of the largest circular microlens on the main spoke is also 3.9mm. The distance between the center points of the lenses is 21.9 mm. Between each pair of main spokes, there is an additional spoke and two end spokes. The additional spokes start between the second and third main rings of the main spokes and end between the tenth and eleventh main rings of the main spokes. Each additional spoke has nine gradually increasing circular microlenses, which are spread out to form nine additional rings. Each additional ring has the same number of circular microlenses, for a total of 216 circular microlenses. The two end spokes consist of four circular microlenses of the same size, arranged left and right between the ninth additional ring and the twelfth main ring to form two end rings. Each end ring has the same number of circular microlenses, for a total of 96 circular microlenses.

[0015] The diameter of the first main ring circular microlens of the main spoke is 0.8 mm; the diameter of the second main ring circular microlens is 0.85 mm, and so on, with the diameter of the main ring circular microlens gradually increasing, until the diameter of the twelfth main ring circular microlens is 1.35 mm.

[0016] The diameter of the first additional ring circular microlens of the additional spoke is 0.85 mm; the diameter of the second additional ring circular microlens is 0.90 mm, and so on, with the diameter of the additional ring circular microlens gradually increasing, until the diameter of the ninth additional ring circular microlens is 1.20 mm; the diameter of the two end ring circular microlenses of the end spoke is 1.0 mm.

[0017] By adopting the above structure, this invention, based on myopia lenses, improves upon the shortcomings of single-vision myopia lenses by forming concentric, progressively larger multifocal circular microlenses outside the central convex area for myopia. This mitigates the progression of myopia. Furthermore, the microlens design, with its gradually increasing diameter from the outermost ring compared to a microlens of constant size, better aligns with the characteristics of eye vision. The larger microlens area at the eye's edge allows for greater relaxation of the ciliary muscle, reducing eye fatigue and preventing myopia progression. Moreover, the progressively larger circular microlenses contribute to myopia control. This is because the microlens design is based on the principle of hyperopia lenses. In myopic individuals, the ciliary muscle is constantly tense, while the microlens, operating on the opposite principle, shifts the image from behind the retina to in front of it, making vision easier and relaxing the ciliary muscle. This provides relief and adjustment to the ciliary muscle, thus controlling myopia. Meanwhile, based on myopia lenses, this invention reduces contrast by using diffusion points in the point diffusion area outside the concave area at the center of the lens for myopia, and greatly improves the myopia suppression effect by combining light scattering technology.

[0018] More importantly, compared with existing patents, this utility model avoids the corresponding position of the circular microlens by having the diffusion point avoid the corresponding position of the circular microlens, so that the convex circular microlens and the diffusion point of the concave surface do not coincide. The bottom surface of the circular microlens is intact, and the second refractive power of the circular microlens is not affected by the diffusion point. This can ensure the adjustment and relaxation effect of the circular microlens in the defocus area on the ciliary muscle, and further ensure the improvement of the myopia suppression effect.

[0019] Furthermore, the second refractive section of this invention comprises a main spoke, auxiliary spokes, and a final spoke, composed of numerous circular microlenses. Twelve main rings are formed on the main spokes, nine auxiliary rings on the auxiliary spokes, and two final rings on the final spokes. The diameter of each row of microlenses on the main and auxiliary spokes gradually increases outwards, with the innermost ring having the smallest diameter and the diameter increasing towards the outermost edge. The number of microlenses on each main ring of the main spokes and the number of microlenses on each auxiliary ring of the auxiliary spokes are the same. The advantage of this design is that, compared to other patents, the structural design of this invention better conforms to the characteristics of the eyeball. By designing a radial fiber morphology similar to that within the ciliary muscle of the human eye, the adjustment of the ciliary muscle is more flexible. The outermost rings are larger, and the microlenses are larger, making it easier for the eye to view near objects in all directions, further relieving the tension of the ciliary muscle and inhibiting myopia progression. The design of the auxiliary and final spokes compensates for the situation where the gap between the main spokes is too large, resulting in poor myopia suppression, making myopia control technology more precise.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0041] It should be noted that the terms front, back, inside, outside, top, bottom, left, right, first, second, third, etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the technical features indicated, unless otherwise explicitly defined.

[0042] like Figures 4 to 9 As shown, this utility model discloses a defocused light diffusion composite lens.

[0043] The myopia substrate 10 has a myopia-use convex region A1 at the center of its convex surface, and a defocus region B around the myopia-use convex region A1. Several protruding circular microlenses B1 are arranged in the defocus region B. The circular microlenses B1 on the myopia substrate 10 have a second refractive power to inhibit the development of myopia, and the rest of the myopia substrate 10, excluding the circular microlenses B1, have a first refractive power to correct myopia.

[0044] An inner reinforcing layer 21 is coated onto the concave surface of the myopia substrate 10, and an outer reinforcing layer 22 is coated onto the convex surface of the myopia substrate 10. Both the inner and outer reinforcing layers 21 and 22 have a thickness of 3-8 μm, providing the lens with abrasion and scratch resistance. An inner OAR film 31 is deposited on the inner reinforcing layer 21 via vacuum evaporation, and an outer OAR film 32 is deposited on the outer reinforcing layer 22 via vacuum evaporation. Both the inner and outer OAR film layers 31 and 32 have a thickness of 90-110 nm, reducing reflected light from the back of the lens and improving vision. The top of the circular microlens B1 protrudes beyond the outer reinforcing layer 22 and the outer OAR film 32. The power of the circular microlens B1 is controlled between +2.00D and +6.00D.

[0045] A concave region A2 for myopia correction is provided at the center of the inner OAR film layer 31. A dot diffusion region C is etched around the concave region A2. Several recessed diffusion points C1 are evenly distributed within the dot diffusion region C, avoiding the corresponding positions of the circular microlens B1. Figure 4 and Figure 5 As can be seen from the perspective, the position of the diffusion point C1 avoids the corresponding position of the circular microlens B1, so that the convex circular microlens B1 and the concave diffusion point C1 do not coincide. Figure 5 The circular microlens B1 shown is a blank circle. In this way, because the diffusion point C1 avoids the corresponding position of the circular microlens B1, the bottom surface of the circular microlens B1 remains intact. The secondary refractive power of the circular microlens B1 is not affected by the diffusion point C1, ensuring the relaxing effect of the circular microlens B1 on the ciliary muscle in the defocus area B, further ensuring the improved effect of myopia suppression. This is the key design feature of this invention.

[0046] This invention is further optimized in that the convex region A1 for myopia is larger than the concave region A2 for myopia. The diameter D1 of the convex region A1 is 7-12 mm, and the diameter D4 of the concave region A2 is 5 mm. The defocus region B is less than or equal to the dot diffusion region C. The diameter D2 of the defocus region B is 40-70 mm, and the diameter D3 of the dot diffusion region C is 70-76 mm. The diameter of each diffusion point C1 is 0.2 mm, and the engraving depth of each diffusion point C1 is 0.1-0.8 mm.

[0047] This invention is further optimized so that when the diameter D2 of the defocus region B is 44mm, the defocus region B is composed of 600 circular microlenses B1 arranged in a certain regular pattern. Specifically, 24 main spokes 11 are evenly distributed outward from the outer edge of the convex region A1 of the myopic eye in the defocus region B. Each main spoke 11 has 12 gradually increasing circular microlenses B1 distributed on it, thus spreading out to form 12 main rings 12. The smallest circular microlenses B1 on the main spoke 11 form the first main ring 12 on the main spoke 11. There are 24 circular microlenses B1 on the first main ring 12. The number of circular microlenses B1 on each main ring 12 is the same, for a total of 288 circular microlenses B1. The distance L1 from the optical center of the lens to the center point of the smallest circular microlens B1 on the main spoke 11 is 3.9mm, and the distance L2 from the optical center of the lens to the center point of the largest circular microlens B1 on the main spoke 11 is 21.9mm. Between every two main spokes 11, there is an additional spoke 13 and two end spokes 15. The additional spokes 13 begin between the second and third main rings 12 of the main spokes 11 and end between the tenth and eleventh main rings 12 of the main spokes 11. Each additional spoke 13 has nine progressively larger circular microlenses B1, which spread out to form nine additional rings 14. Each additional ring 14 has the same number of circular microlenses B1, for a total of 216 circular microlenses B1. The two end spokes 15 consist of four identical circular microlenses B1, arranged left and right between the ninth additional ring 14 and the twelfth main ring 12, forming two end rings 16. Each end ring 16 has the same number of circular microlenses B1, for a total of 96 circular microlenses B1.

[0048] This invention is further optimized in that the diameter of the circular microlens B1 of the first main ring 12 of the main spoke 11 is 0.8 mm; the diameter of the circular microlens B1 of the second main ring 12 is 0.85 mm, and so on, gradually increasing with the diameter of the circular microlens B1 of the main ring 12, until the diameter of the circular microlens B1 of the twelfth main ring 12 is 1.35 mm. The diameter of the circular microlens B1 of the first auxiliary ring 14 of the auxiliary spoke 13 is 0.85 mm; the diameter of the circular microlens B1 of the second auxiliary ring 14 is 0.90 mm, and so on, gradually increasing with the diameter of the circular microlens B1 of the auxiliary ring 14, until the diameter of the circular microlens B1 of the ninth auxiliary ring 14 is 1.20 mm. The diameter of the two circular microlenses B1 of the two end rings 16 of the end spoke 15 is 1.0 mm.

[0049] Taking PC lenses as an example, the specific process steps for manufacturing this utility model are as follows:

[0050] The first step is to use PC material as raw material, dehumidify the plastic granules, and then use a mold to injection mold them to form a myopia substrate 10.

[0051] During injection molding, a circular microlens B1 is formed on the myopia substrate 10 using a mold, creating a convex region A1 and a defocus region B on the convex surface of the myopia substrate 10. The power of the circular microlens B1 is controlled between +2.00D and +6.00D, the diameter D1 of the convex region A1 is controlled between 7-12mm, and the diameter D2 of the defocus region B is controlled between 40-70mm.

[0052] The second step involves coating an inner reinforcing layer 21 and an outer reinforcing layer 22 onto the concave and convex surfaces of the myopia substrate 10. The thickness of the inner reinforcing layer 21 and the outer reinforcing layer 22 is controlled at 3-8 μm to give the lens a wear-resistant and scratch-resistant effect.

[0053] The third step involves forming an inner OAR film layer 31 and an outer OAR film layer 32 on the inner strengthening layer 21 and the outer strengthening layer 22 by vacuum evaporation. The thickness of the inner OAR film layer 31 and the outer OAR film layer 32 is controlled at 90-110nm, which can reduce the reflected light from the back of the lens to the eye and make the vision clearer.

[0054] At this time, the top of the circular microlens B1 on the convex surface of the myopia substrate 10 protrudes from the outer reinforcing layer 22 and the outer OAR film layer 32.

[0055] Fourthly, on the surface of the inner OAR film layer 31, several diffusion points C1 are formed by laser engraving, avoiding the corresponding positions of the circular microlens B1, thus forming the concave area A2 and the dot diffusion area C for myopia. Through perspective, it can be seen that the convex circular microlens B1 and the concave diffusion points C1 do not coincide. Figure 5 The circular microlens B1 shown is a blank circle. The diffusion points C1 correspond only to the gaps between the circular microlenses B1. The diameter D4 of the concave area A2 for myopia is controlled at 5 mm, and the diameter D3 of the point diffusion area C is controlled at 70-76 mm. The diffusion points C1 are all the same size, with a diameter controlled at 0.2 mm and an engraving depth controlled at 0.1-0.8 mm.

[0056] This completes the processing and production of the myopia control lens of this utility model.

[0057] The first feature of this invention is that the diffusion point C1 on the concave surface is avoided from the corresponding position of the circular microlens B1 on the convex surface, so that the circular microlens B1 on the convex surface and the diffusion point C1 on the concave surface do not coincide. The second refractive power of the circular microlens B1 is not affected by the diffusion point C1, which can ensure the adjustment and relaxation effect of the circular microlens B1 on the ciliary muscle in the defocus area B, and further ensure the improvement of the myopia suppression effect.

[0058] The second feature of this invention is that the second refractive section is composed of numerous circular microlenses B1 forming a main spoke 11, auxiliary spokes 13, and a final spoke 15. Twelve main rings 12 are formed on the main spokes 11, nine auxiliary rings 14 are formed on the auxiliary spokes 13, and two final rings 16 are formed on the final spokes 15. The diameter of each row of microlenses on the main spokes 11 and auxiliary spokes 13 gradually increases outwards, with the innermost ring having the smallest diameter and the diameter increasing towards the outermost edge. Furthermore, the number of microlenses on each main ring 12 of the main spokes 11 and the number of microlenses on each auxiliary ring 14 of the auxiliary spokes 13 are the same. Thus, compared to other patents, the structural design of this invention is more in line with the characteristics of the eyeball. By designing a radial fiber morphology similar to that within the ciliary muscle of the human eye, the adjustment of the ciliary muscle is more flexible. The outermost rings are larger, and the microlenses are larger, making it easier for the eye to view near objects in all directions, further relieving the tension of the ciliary muscle and inhibiting the progression of myopia. The design of the additional spokes 13 and the tail spokes 15 compensates for the poor myopia suppression effect caused by the large gap between the main spokes 11 and the tail spokes 15, making myopia control technology more precise.

[0059] The above description is merely an example of the implementation of this utility model and is not intended to limit the scope of protection of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this case, shall fall within the scope of protection of this case.
