Description

Technical Field

[0001] This utility model relates to the field of composite microstructure lens technology, specifically to a multifunctional lens with photolithographic ultramicrostructure for myopia prevention and delay. Background Technology

[0002] Composite microstructure lenses are a new type of eyeglass lens that uses tiny structures added to the lens to alter the path of light, thereby improving vision and slowing the progression of myopia.

[0003] First, existing myopia control lenses struggle to balance effectiveness and comfort. One type of product prioritizes control with a high-density design, which significantly slows myopia progression but may cause blurred vision and discomfort for initial wearers. The other type focuses on the user's subjective visual experience with a low-density design, improving visual quality but offering limited myopia control. Both types of lenses are mostly manufactured using molds, making it difficult to create smaller microstructural units, requiring an adaptation period for initial wearers. Second, long-term use leads to performance degradation. Because current designs use mostly fixed optical parameters lacking dynamic variation, prolonged use of the same product causes the brain to gradually adapt to the intervention, becoming "accustomed" to the stimulus and no longer responding to the optical design, resulting in a gradual decline in control effectiveness. Therefore, variable stimuli are needed to maintain long-term control efficacy, but current limitations in mold precision, high costs, and product yield rates prevent further miniaturization of microstructures. Furthermore, existing laser-based point diffusion technologies also face challenges in precisely controlling haze. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multifunctional lens with photolithographic microstructure for myopia prevention and delay, addressing the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multifunctional lens with a photolithographic microstructure for myopia prevention and delay, comprising a lens body, wherein the lens body has a functional area inside, the functional area includes a central optical correction area on the inner side, a photolithographic microlens multifunctional structure area on the outer side of the central optical correction area, and an annular blank area on the outer side of the photolithographic microlens multifunctional structure area, wherein the central optical correction area and the photolithographic microlens multifunctional structure area constitute the functional area arrangement; The total diameter of the main lens is set to 60mm~80mm, the diameter of the functional area is set to 40mm~60mm, the diameter of the central optical correction area is set to 3mm~5mm, the photometric range is set to +2.00~-12.00DS, 0~-4.00DC, and the photometric step interval is set to 0.06D~0.12D. The photolithographic microlens multifunctional structure area is composed of multiple microlens rings, each microlens ring is composed of multiple microlenses with a diameter of 0.05~0.3mm, the photometric range of the microlenses is set to +12.00D~-12.00D, and the annular blank area is set to a width of 5mm-20mm outside the photolithographic microlens multifunctional structure area.

[0006] Furthermore, the photolithographic microlens multifunctional structure region features a negative defocus setting for the microlens ring, with the microlens photometric range being -0.25D to -10.00D, and the negative defocus setting of the microlens ring changing by +0.02D for each layer from the inside out.

[0007] Furthermore, the microlens ring of the photolithographic microlens multifunctional structure region is positively defocused, and the photoluminescence range of the microlens is set to +0.25D to +10.00D. The negative defocus of the microlens ring changes by -0.02D for each layer from the inside to the outside.

[0008] Furthermore, the microlens rings of the photolithographic microlens multifunctional structure region are arranged alternately with positive and negative defocusing single rings, and the microlens photometric range is set from +10.00D to -10.00D. The microlens rings of the photolithographic microlens multifunctional structure region are arranged with alternating positive and negative single layers from the inside to the outside.

[0009] Furthermore, the microlens rings of the photolithographic microlens multifunctional structure region are arranged in alternating positive and negative defocusing rings, and the microlens photometric range is set from +10.00D to -10.00D. The microlens rings of the photolithographic microlens multifunctional structure region are arranged in multiple alternating positive and negative rings from the inside to the outside.

[0010] Furthermore, multiple diffusion light spot structures with a diameter of 0.01~0.05mm are distributed between the multiple microlenses.

[0011] Furthermore, the outer side of the lens body is covered with a film structure containing photochromic material, wherein the film structure is a spiropyran compound film structure.

[0012] With the above structure, the photolithographic microstructure multifunctional lens of this invention for myopia prevention and delay has the following advantages: the microlens forms a dense negative defocus signal interference area, and because the size is small enough, it does not cause visual fluctuations. When the eye moves, the light passing through this area will produce irregular dynamic changes in different states such as convergence and divergence. At the same time, it diffuses at the inter-composite points in the gaps of the photolithographic microlens, further reducing the contrast of the light signal entering the eye. This comprehensive design can minimize the intensity of the negative defocus signal reaching the retina, prevent the brain from receiving negative defocus signals that may accelerate the development of myopia, and thus achieve a near-imperceptible effect of delaying the occurrence and development of myopia. For the photophobia that occurs when using low-concentration atropine to control myopia, a photochromic film layer can be added to adjust the brightness of the light entering the eye to alleviate the symptoms.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figs. 1-3 A multifunctional lens with a photolithographic microstructure for myopia prevention and delay includes a lens body 1, wherein the lens body 1 has a functional area inside, the functional area including a central optical correction area 2 on the inner side, characterized in that: the lens body 1 has a photolithographic microlens multifunctional structure area 3 outside the central optical correction area 2, and an annular blank area 4 is provided outside the photolithographic microlens multifunctional structure area 3, the central optical correction area 2 and the photolithographic microlens multifunctional structure area 3 forming a functional area arrangement; The lens body 1 has a total diameter of 60mm to 80mm, the functional area has a diameter of 40mm to 60mm, the central optical correction area 2 has a diameter of 3mm to 5mm, the power range is +2.00 to -12.00DS (myopia) and 0 to -4.00DC (astigmatism), and the power step interval is 0.06D to 0.12D. The photolithographic microlens multifunctional structure area 3 is composed of multiple microlens rings, each microlens ring consisting of multiple microlenses with a diameter of 0.05 to 0.3mm. The power range of the microlenses is +12.00D to -12.00D. The annular blank area 4 is 5mm to 20mm wide on the outer side of the photolithographic microlens multifunctional structure area 3.

[0019] It employs ultra-microlenses smaller than 0.3mm. Due to the reduced area, the number of microstructures per unit area increases, leading to a higher fill rate of the entire lens's functional area. Simultaneously, these microstructures are less noticeable to the brain, making visual perception less susceptible to interference. This achieves improved visual experience while maintaining effective control and imaging intervention, making it more suitable for long-term wear.

[0020] Specific implementation 1: The photolithographic microlens multifunctional structure region 3 has a microlens ring with negative defocusing. The microlens photometric range is -0.25D to -10.00D, and the negative defocusing of the microlens ring changes by +0.02D for each layer from the inside to the outside.

[0021] For example, the light intensity decreases sequentially from the inside out to enhance the control effect in the central area. The light intensity of the first microlens in the innermost ring is -8.00D, the second ring is -7.98D, and so on, with each ring changing by 0.02D. Alternatively, the defocus amount can be fixed uniformly, such as -8.00D.

[0022] Specific Implementation 2: The photolithographic microlens multifunctional structure region 3 has a positive defocus setting for the microlens ring, and the microlens photometric range is set to +0.25D to +10.00D. The negative defocus setting of the microlens ring changes by -0.02D for each layer from the inside to the outside.

[0023] For example, the light intensity decreases sequentially from the inside out to enhance the control effect in the central area. The light intensity of the first ring of microlenses in the innermost circle is +8.00D, the second ring is +7.98D, and so on, with each ring changing by 0.02D. Alternatively, the defocus amount can be fixed uniformly, such as +8.00D.

[0024] Specific implementation 3: The photolithographic microlens multifunctional structure region 3 has alternating positive and negative defocusing single rings of microlens rings arranged in alternating patterns. The photoluminescence range of the microlens is set from +10.00D to -10.00D. The photolithographic microlens multifunctional structure region 3 has alternating positive and negative single-layer microlens rings arranged from the inside to the outside.

[0025] For example, the first innermost ring of microlenses has a photometric power of +8.00D, the second ring has -8.00D, the third ring has +8.00D, and so on, alternating. Similarly, it can be arranged from negative to positive, with the first innermost ring of microlenses having a photometric power of -8.00D, the second ring having +8.00D, the third ring having -8.00D, and so on, alternating.

[0026] Specific implementation 4: The photolithographic microlens multifunctional structure region 3 has multiple microlens rings with alternating positive and negative defocusing, and the microlens photometric range is set from +10.00D to -10.00D. The microlens rings in the photolithographic microlens multifunctional structure region 3 are arranged with multiple alternating positive and negative rings from the inside to the outside.

[0027] For example, the photoluminescence of the innermost rings 1-2 is +8.00D, the photoluminescence of the innermost rings 3-4 is -8.00D, the photoluminescence of the innermost rings 5-6 is +8.00D, and so on, alternating. Similarly, it can also be arranged from negative to positive, with the photoluminescence of the innermost rings 1-2 being -8.00D, the photoluminescence of the innermost rings 3-4 being +8.00D, the photoluminescence of the innermost rings 5-6 being -8.00D, and so on, alternating. It can also be arranged in three or more alternating rings.

[0028] Specific Implementation 5: Multiple diffusion light spot structures 5 with a diameter of 0.01~0.05mm are distributed between the aforementioned microlenses. That is, a dot matrix scattering structure is fabricated in the gap between the photolithographic microlenses using a nanoscale photolithography process. This area contains hundreds of thousands of micro- and nano-structures with a diameter of 0.01~0.05mm, which can decompose the incident light into multiple weak light spots, forming a uniform dot diffusion effect. These diffusion light spots will form a blurred but wider light signal distribution around the retina, further weakening the intensity of the negative defocus signal, while reducing the excitability of retinal photoreceptor cells and inhibiting the tendency of excessive posterior elongation of the eye axis. The diffusion light spot structure 5 can combine dot diffusion to reduce contrast, and the multi-effect combined myopia control effect is better.

[0029] Specific Implementation 6: The outer side of the lens body 1 is covered with a film structure containing photochromic material, and the film structure is a film structure containing spiropyran compounds.

[0030] To address the photophobia symptoms commonly experienced by teenagers using low-concentration atropine for myopia control, the photolithographic microlens composite photochromic film effectively improves these symptoms through a triple-structure design of "optical correction + myopia control + dynamic light adjustment." Specifically, a layer containing photochromic material is coated using vacuum deposition technology. Under ultraviolet light and strong light, this film rapidly undergoes molecular structure changes, transforming from a transparent state to a light-blocking state such as light gray or brown, reducing light transmittance, protecting the eyes, and alleviating photophobia. When the light weakens, the molecular structure automatically recovers, and the film returns to transparency. The sensitivity of the color-changing reaction and the degree of light blocking can be precisely controlled by adjusting the material formula, ensuring that while effectively alleviating photophobia, normal visual clarity is not affected.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
