Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of lenses, and in particular relates to an invisible grid micro-light unit anti-glare lens. Background Art
[0002] Glare refers to visual discomfort and reduced visibility caused by an inappropriate brightness distribution or extreme brightness contrast in space or time within the field of view. This creates a brightness sensation within the field of view that the human eye cannot adapt to, potentially causing nausea, discomfort, or even loss of vision. Excessive brightness or significant brightness fluctuations in a specific area of the field of view are major causes of visual fatigue. The human eye's normal range of attention is 30° horizontal to 60° downward; glare is any glare within this range.
[0003] At present, people often wear anti-glare glasses for anti-glare protection. However, most of the current anti-glare glasses have an anti-glare film coated on the outer surface of the lens. Over time, they are prone to oxidation and wear, have poor durability, and have poor anti-reflection effects on multi-angle stray light and strong light.
[0004] Therefore, a new, efficient anti-glare lens is urgently needed. Summary of the Invention
[0005] In view of this, the technical problem to be solved by the present invention is to provide an invisible grid micro-light unit anti-glare lens, which realizes anti-glare protection by arranging an anti-glare film with an ITO film layer on the inner layer of the resin monomer. At the same time, a micro-light unit is arranged on the surface of the front piece of the resin monomer to increase the anti-reflection effect, thereby avoiding the trouble of poor anti-glare performance and weak anti-reflection effect of previous lenses.
[0006] In order to solve the above technical problems, the present invention discloses an invisible grid micro-light unit anti-glare lens, which includes: a resin monomer front sheet;

[0009] The front surface of the resin monomer front sheet has convex or concave micro-light units, and the micro-light units are located in the grid of the ITO film layer.
[0010] According to one embodiment of the present invention, the ITO film layer is deposited on the surface of the anti-glare film by vacuum sputtering.
[0011] According to one embodiment of the present invention, the mesh pores of the ITO film layer are set to nanometer level.
[0012] According to one embodiment of the present invention, the mesh pore size of the ITO film layer is 300-900 nm.
[0013] According to one embodiment of the present invention, the resin monomer front sheet is coated with an anti-reflection film layer, which is composed of multiple layers of low-refractive-index film layers and high-refractive-index film layers of different thicknesses.
[0014] According to one embodiment of the present invention, the above-mentioned anti-reflection film layer is set to 7 layers, including a first low refractive index film layer with a thickness of 33-35nm, a second high refractive index film layer with a thickness of 18-27nm, a third low refractive index film layer with a thickness of 21-26nm, a fourth high refractive index film layer with a thickness of 44-48nm, a fifth low refractive index film layer with a thickness of 14-18nm, a sixth high refractive index film layer with a thickness of 32-38nm, and a seventh low refractive index film layer with a thickness of 91-95nm.
[0015] According to one embodiment of the present invention, a waterproof film layer is provided on the outer surface of the anti-reflection film layer.
[0016] According to an embodiment of the present invention, the micro-light unit adds positive or negative refractive power relative to the resin monomer front sheet.
[0017] Compared with the prior art, the present invention can achieve the following technical effects:
[0018] Anti-glare protection is achieved by setting an anti-glare film with an ITO film layer on the inner layer of the resin monomer. At the same time, a micro-light unit is set on the front surface of the resin monomer to increase the anti-reflection effect, avoiding the problems of poor anti-glare performance and weak anti-reflection effect of previous lenses.

[0024] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] Please refer to Figure 1 , Figure 1 Schematic diagram of an invisible grid micro-light unit anti-glare lens according to an embodiment of the present invention.
[0026] As shown in the figure, an invisible grid micro-light unit anti-glare lens includes: a resin monomer front piece 10; an anti-glare film 20 arranged on the rear side of the resin monomer front piece 10, and the front surface of the anti-glare film 20 has a grid-shaped ITO film layer 21; a resin monomer rear piece 30 arranged on the rear side of the anti-glare film 20; wherein, the front surface of the resin monomer front piece 10 has raised or recessed micro-light units, and the micro-light units are located in the grid of the ITO film layer 21.
[0027] In one embodiment of the present invention, the anti-glare film 20 is a polymer anti-glare film, preferably a PET film layer, on the surface of which an ITO film layer 21 is vacuum sputtered. This film layer can effectively absorb stray strong light, has a high light transmittance, and is arranged in a grid pattern. During the lens production process, the anti-glare film 20 with the film layer can be placed in an apron, and then a glass mold is laminated on the front and back sides of the film. Resin monomer is injected into the glass mold and the anti-glare film 20, and solidified to form the resin monomer front sheet 10 and the resin monomer back sheet 30, thereby forming the anti-glare lens substrate. It should be understood that the anti-glare film 20 is arranged slightly closer to the resin monomer front sheet 10, thereby first providing anti-glare protection at the front end of the substrate to improve efficiency, while the resin monomer back sheet 30 on the back side provides the main demand for diopter.
[0028] In addition, a convex or concave micro-light unit is provided on the front side of the resin monomer front sheet 10. Preferably, the mesh of the ITO film layer 21 is set to the nanometer level, and the micro-light unit is also nanometer-level, which is relatively arranged within the mesh of the ITO film layer 21 to achieve transmission from the micro-light unit to the ITO film layer 21. The convex or concave micro-light unit can well refract and reflect stray light to the surrounding ITO film layer 21, thereby filtering out stray strong light and making it more comfortable to wear.
[0029] Preferably, the mesh aperture of the ITO film layer 21 is 300-900 nm, which makes it more comfortable to wear.
[0030] In addition, the micro-light unit increases the positive or negative refractive power relative to the resin monomer front plate 10, thereby being used in conjunction with multifocal progressive lenses to improve eye comfort.
[0031] The resin monomer front sheet 10 of the present invention is coated with an anti-reflection film layer 40 . The anti-reflection film layer 40 is composed of multiple layers of low-refractive index film layers and high-refractive index film layers of different thicknesses, and is used to further improve the anti-reflection function of the lens.
[0032] Furthermore, the anti-reflection film 40 is provided with 7 layers, including a first low-refractive index film layer with a thickness of 33-35nm, a second high-refractive index film layer with a thickness of 18-27nm, a third low-refractive index film layer with a thickness of 21-26nm, a fourth high-refractive index film layer with a thickness of 44-48nm, a fifth low-refractive index film layer with a thickness of 14-18nm, a sixth high-refractive index film layer with a thickness of 32-38nm, and a seventh low-refractive index film layer with a thickness of 91-95nm. The seven layers of low and high refractive index films work together to filter out stray light in different wavelength bands, effectively improving light transmission, reducing eye fatigue, and providing more comfortable wear.
[0033] In addition, the outer surface of the anti-reflection film layer 40 is provided with a waterproof film layer, which can be made of anti-fog material by plating or coating.
[0034] In summary, the present invention achieves anti-glare protection by arranging an anti-glare film with an ITO film layer on the inner layer of the resin monomer, and at the same time arranges a micro-light unit on the surface of the front sheet of the resin monomer to increase the anti-reflection effect, thereby avoiding the problems of poor anti-glare performance and weak anti-reflection effect of previous lenses.
[0035] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
