Description
Technical Field
[0001] The utility model relates to the technical field of lenses, in particular to the structure of a high-definition multifunctional lens. Background Art
[0002] Traditional polarized lenses are made by combining a polarizing film on a lens substrate, such as combining a polarizing film on the convex surface of the lens substrate, combining a polarizing film on the concave surface of the lens substrate, combining a polarizing film on both the convex and concave surfaces of the lens substrate, or sandwiching a polarizing film between two substrates. The existing polarizing film is composed of TAC (triacetate), PVA (polyvinyl alcohol) and TAC (triacetate), which gives the lens product a polarizing function, so that it can selectively block light in certain directions and only allow light in specific directions to pass through, thereby blocking glare, reflected light and other stray light. However, when the aforementioned traditional polarized lenses are used in different scenes and environments, especially in some places with very strong reflections and astigmatism, they cannot accurately block stray light of boundary colors such as blue-green, yellow-green, red-orange, etc., such as outdoor ski resorts, fishing waters, golf courses, etc., which easily makes the boundaries of the obtained images unclear and objects cannot be seen clearly. Although the lens industry is constantly innovating and developing polarized lenses with various functions, the existing polarized lenses still have relatively single functions or insufficient functions, and cannot meet people's usage needs in different scenes and various environments, and their scope of use is limited. Therefore, the inventor, relying on the long-term accumulated professional knowledge and familiarity with lens products, conducted in-depth research, summarized the characteristics of the product, and specially developed and designed a high-definition multifunctional lens, which resulted in this case.

[0003] The utility model aims to provide a high-definition multifunctional lens, which has the multiple functions of color change, stray light filtering, high definition and impact resistance.
[0004] In order to achieve the above purpose, the solution of the utility model is:
[0005] A high-definition multifunctional lens comprises a lens substrate, a color-changing layer, a hardening layer, a nano-coating layer, a waterproof layer, an oil-proof layer and an anti-fog layer; a color-changing layer is compounded on the convex surface of the lens substrate, a hardening layer is compounded on the color-changing layer, and a nano-coating layer is compounded on the hardening layer, the nano-coating layer is formed by alternatingly stacking three layers of titanium pentoxide and three layers of silicon dioxide, and the thickness of the three layers of titanium pentoxide is 23nm, 120nm and 70nm from the concave surface to the convex surface of the substrate, the thickness of the three layers of silicon dioxide is 53nm, 82nm and 123nm from the concave surface to the convex surface of the substrate, a waterproof layer is compounded on the nano-coating layer, and an oil-proof layer is compounded on the waterproof layer; an anti-fog layer is compounded on the concave surface of the lens substrate.

It can also resist impact, and the product safety meets the requirements of American standards, Australian standards, and European standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] It should be noted that the terms up, down, left, right, inside, outside, first, second, etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features, unless otherwise clearly and specifically defined.
[0025] like Figures 1 to 4 As shown, the utility model discloses a high-definition multifunctional lens, and the first embodiment includes a lens substrate 1, a polarizing layer 2, a color-changing layer 3, a hardening layer 4, a nano-coating layer 5, a waterproof layer 6, an oil-proof layer 7 and an anti-fog layer 8.
[0026] The lens substrate 1 is a PC sheet, a nylon sheet, a CR sheet or an acrylic sheet.
[0027] The convex surface of the lens substrate 1 is compounded with a polarizing layer 2 by injection molding. The polarizing layer 2 enables the lens product to have a polarizing function, forming a polarized lens, which can selectively block light in certain directions and only allow light in a specific direction to pass, thereby blocking glare, reflected light and other stray light.
[0028] The polarized lens is compounded with a color-changing layer 3 on the convex polarizing layer 2 by spin coating a color-changing liquid, and then pre-dried to firmly combine the color-changing layer 3 with the polarizing layer 2. The color-changing liquid of the color-changing layer 3 can specifically be a spiropyran or spirooxazine photochromic material, and the thickness of the spin-coated color-changing layer 3 is controlled to be 5-10μm. Because the color-changing layer 3 is only formed on the convex surface of the lens by spin coating, the amount of color-changing liquid is small and the cost is low. The color-changing layer 3 allows the color change rate of the lens product to meet international standards, and can change from 0# to 3#, or from 0# to 4#, so that the light transmittance of the lens is reduced from 83-85% to 18-30%, and the color change effect can ensure durability, greatly reducing the damage of strong light to the eyes.
[0029] The polarized lens is compounded with an anti-fog layer 8 on the concave surface of the lens substrate 1 by spin coating an anti-fog liquid, and then pre-dried to firmly bond the anti-fog layer 8 to the concave surface of the lens substrate 1. The anti-fog layer 8 has a washable anti-fog function, so that the lens can pass the European standard EN166 anti-fog test standard, the anti-fog function can be maintained permanently and can be washed, the lens can avoid fogging during use, and the use covers a wider range. Because the anti-fog layer 8 is only formed on the concave surface of the lens by spin coating, the amount of anti-fog liquid is small, the cost is low, and the anti-fog liquid is not attached to the side edge of the lens, so that the front and side of the lens are not afraid of impact, and the lens product can pass the Z87.1 impact test.
[0030] A hardening layer 4 is formed on the color-changing layer 3 by coating a hardening liquid, and then completely dried. A nano-coating layer 5 is then formed on the hardening layer 4 by vacuum coating. The hardening layer 4 enables full coating on the lens without the need for a bridging layer, optimizes the process, saves processing costs, and improves the yield rate. Specifically, when the lens revolves and rotates in a vacuum device, the coating material is attached to the surface of the lens to form a uniform optical film layer, and the thickness of the optical film layer is calculated in nanometers. Specifically, the nano-coating layer 5 is formed by alternatingly stacking three layers of titanium pentoxide 51, 53, and 55 and three layers of silicon dioxide 52, 54, and 56, and the three layers of titanium pentoxide 51, 53, and 55 are arranged in sequence from the concave surface to the convex surface of the substrate 1, the thickness of the titanium pentoxide 51 is 23nm, the thickness of the titanium pentoxide 53 is 120nm, and the thickness of the titanium pentoxide 55 is 70nm. The three layers of silicon dioxide 52, 54, and 56 are arranged in sequence from the concave surface to the convex surface of the substrate 1, the thickness of the silicon dioxide 52 is 53nm, the thickness of the silicon dioxide 54 is 82nm, and the thickness of the silicon dioxide 56 is 123nm. Different optical properties are achieved by stacking materials with different refractive indices layer by layer, such as Figure 4 As shown, when the lens becomes lighter, it can accurately block 50% of the 490nm blue-green stray light, 55% of the 580nm yellow-green stray light, and 40% of the 680nm red-orange stray light, so that the lens can effectively block reflected harmful light when used outdoors, with high-definition visual effects, allowing users to wear it more clearly and transparently. When the lens becomes darker, it can block 80% of the 490nm blue-green stray light, 92% of the 580nm yellow-green stray light, and 66% of the 680nm red-orange stray light.
[0031] A waterproof layer 6 is compounded on the nano-coating layer 5 by spin coating, and an oil-proof layer 7 is compounded on the waterproof layer 6 by spin coating, so that the lens has the function of being waterproof and oil-proof.
[0032] The lens of the utility model has multiple functions such as polarization, color change, high definition and impact resistance. The product test results of Example 1: the single perspective rate is 45±2%, the polarization rate is>80%, and the product complies with the international standard ISO 12312-1:2022, the Australian standard AS / NZS1067.1:2016, the European standard EN 1836:2005, the American standard ANSI Z80.3-2018 and the Canadian standard CSAZ94-3-20. The product involves a wide range of usage scenarios and is suitable for outdoor sports, with clearer vision.
[0033] like Figure 5 to Figure 6 As shown, the utility model discloses a high-definition multifunctional lens, embodiment 2 includes a lens substrate 1, a polarizing layer 2, a color-changing layer 3, a hardening layer 4, a nano-coating layer 5, a waterproof layer 6, an oil-proof layer 7, an anti-fog layer 8 and a dyeing layer 9.
[0034] The lens substrate 1 is a PC sheet, a nylon sheet, a CR sheet or an acrylic sheet.
[0035] The convex surface of the lens substrate 1 is compounded with a polarizing layer 2 by injection molding, so that the lens product has a polarizing function.
[0036] The polarized lens is compounded with a dye layer 9 on the convex polarizing layer 2 by spin coating a dyeing liquid, and then dried to firmly combine the dye layer 9 with the polarizing layer 2. In this way, lens products of various colors can be produced by dyeing, which increases the beauty of the products, diversifies the products, and increases the selectivity, so that different consumers can choose products suitable for themselves.
[0037] The dyeing layer 9 is then composited with a color-changing layer 3 by spin coating a color-changing liquid, and then pre-dried to firmly combine the color-changing layer 3 with the polarizing layer 2. The lens product thus has a permanent color-changing effect, reducing the lens transmittance from 83-85% to 18-30%.
[0038] The polarized lens is compounded with an anti-fog layer 8 on the concave surface of the lens substrate 1 by spin coating an anti-fog liquid, and then pre-dried to firmly bond the anti-fog layer 8 to the concave surface of the lens substrate 1, so that the lens product has a washable anti-fog function.
[0039] A hardening layer 4 is formed on the color-changing layer 3 by coating a hardening liquid, and then completely dried. A nano-coating layer 5 is then formed on the hardening layer 4 by vacuum coating. The nano-coating layer 5 is formed by alternating three layers of titanium pentoxide 51, 53, 55 and three layers of silicon dioxide 52, 54, 56, and the three layers of titanium pentoxide 51, 53, 55 are arranged in sequence from the concave surface to the convex surface of the substrate 1. The thickness of the titanium pentoxide 51 is 23nm, the thickness of the titanium pentoxide 53 is 120nm, and the thickness of the titanium pentoxide 55 is 70nm. The three layers of silicon dioxide 52, 54, 56 are arranged in sequence from the concave surface to the convex surface of the substrate 1. The thickness of silicon oxide 52 is 53nm, the thickness of silicon dioxide 54 is 82nm, and the thickness of silicon dioxide 56 is 123nm. Different optical properties are achieved by stacking materials of different refractive indices layer by layer. It can accurately block 50% of 490nm blue-green stray light, 55% of 580nm yellow-green stray light, and 40% of 680nm red-orange stray light, so that the lens can effectively block reflected harmful light when used outdoors, allowing users to wear it more clearly and transparently.
[0040] A waterproof layer 6 is compounded on the nano-coating layer 5 by spin coating, and an oil-proof layer 7 is compounded on the waterproof layer 6 by spin coating, so that the lens has the function of being waterproof and oil-proof.
[0041] Of course, the dyeing layer 9 can also be added between the color-changing layer 3 and the hardening layer 4, or a dyeing layer 9 can be added between the concave surface of the lens substrate 1 and the anti-fog layer 8, or a colored lens substrate 1 can be directly used. In this way, lens products of various colors can also be produced, which increases the beauty of the products, makes the products diversified, and has high selectivity, so that different consumers can choose products suitable for themselves, which will not be explained one by one with figures here.
[0042] In addition, the present invention is not only applicable to polarized lenses, such as the above-mentioned embodiments 1 and 2, which have a polarizing function by adding a polarizing layer 2, but also applicable to non-polarized lenses, that is, removing the polarizing layer 2, which will not be described in detail here.
[0043] The above is only an example of the implementation of the utility model, and is not intended to limit the protection scope of the utility model. It should be pointed out that equivalent changes made by technicians in this field according to the design ideas of this case after reading this specification all fall within the protection scope of this case.
