Description

Technical Field

[0001] This invention belongs to the field of resin lens technology, specifically, it relates to a high-transparency nano-resin lens. Background Technology

[0002] Light reflection on the surface of a lens affects its clarity. The higher the refractive index of the lens material, the greater the reflectivity of the lens surface, resulting in more light loss due to reflection. This phenomenon creates an internal aperture effect within the lens, leading to a noticeable lens thickness. Furthermore, the reflected light can obscure the wearer's vision, causing virtual images, glare, reduced contrast, blurred object outlines, and eye fatigue and discomfort. Therefore, the design of a highly transparent resin lens is urgently needed. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a high-transparency nano-resin lens, so as to avoid the troubles of low clarity, poor light transmission and uncomfortable wear of previous resin lenses.

[0004] To address the aforementioned technical problems, this invention discloses a high-transparency nano-resin lens, comprising:

[0005] Resin substrate;

[0006] A nano-honeycomb film layer is adhered to the front surface of a resin substrate via an organosilicon layer. The nano-honeycomb film layer comprises an inner thermoplastic polyurethane film, a polyvinyl alcohol film, a cellulose triacetate film, and an outer thermoplastic polyurethane film; and

[0007] Functional film layer deposited on the surface of nano-honeycomb film layer;

[0008] Among them, the nano-honeycomb film layer has a honeycomb structure.

[0009] According to one embodiment of the present invention, the honeycomb structure includes a first honeycomb mesh disposed on the surfaces of a polyvinyl alcohol film and a cellulose triacetate film, and a second honeycomb mesh disposed on the surfaces of an inner thermoplastic polyurethane film and an outer thermoplastic polyurethane film, wherein the honeycomb cell size of the second honeycomb mesh is different from that of the first honeycomb mesh.

[0010] According to one embodiment of the present invention, the cell size of the second honeycomb mesh is larger than the cell size of the first honeycomb mesh.

[0011] According to one embodiment of the present invention, the thickness of the inner thermoplastic polyurethane film and the outer thermoplastic polyurethane film is greater than the sum of the thicknesses of the polyvinyl alcohol film and the cellulose triacetate film.

[0012] According to one embodiment of the present invention, the thickness of the above-mentioned nano-honeycomb film layer is 300-700 μm.

[0013] According to one embodiment of the present invention, the above-mentioned functional film layer includes one or more of the following: hardening film, blue light blocking film, red light blocking film, ultraviolet light blocking film, and waterproof film.

[0014] Compared with the prior art, the present invention can achieve the following technical effects:

[0015] By incorporating a nano-honeycomb film layer with a honeycomb structure, the light transmittance of the resin lens is improved, clarity is enhanced, and interference from stray strong light is reduced.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description

[0021] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a high-transparency nano-resin lens according to an embodiment of the present invention.

[0023] As shown in the figure, a high-transparency nano-resin lens includes a resin substrate 10; a nano-honeycomb film layer 30 adhered to the front surface of the resin substrate 10 by an organic silicone layer 20, the nano-honeycomb film layer 30 including an inner thermoplastic polyurethane film 31, a polyvinyl alcohol film 32, a triacetate cellulose film 33, and an outer thermoplastic polyurethane film 34; and a functional film layer 40 deposited on the surface of the nano-honeycomb film layer 30; wherein the nano-honeycomb film layer 30 has a honeycomb structure.

[0024] In one embodiment of the present invention, the resin substrate 10 is cured and molded from resin. After hardening treatment, a high-strength nano-honeycomb film layer 20 is adhered to it through an organosilicon layer 20 to improve the anti-reflective properties of the resin substrate 10. The nano-honeycomb film layer 20 has a honeycomb structure and is composed of an inner thermoplastic polyurethane film 31, a polyvinyl alcohol film 32, a cellulose triacetate film 33, and an outer thermoplastic polyurethane film 34. The inner and outer thermoplastic polyurethane films provide high protection, while the inner polyvinyl alcohol film 32 and cellulose triacetate film 33 improve anti-reflective properties and the polarization effect of stray light. The functional film layer 40 is located on the outermost layer and improves the functionality of the lens through vacuum coating.

[0025] The honeycomb structure, created using nanotechnology, produces lenses that are extremely thin and transparent, effectively reducing pressure during wear without affecting the lens's brightness and transparency. It also effectively suppresses light scattering and reflection, improving lens clarity and color reproduction, thus allowing the wearer to see clearer, more realistic images.

[0026] Specifically, the honeycomb structure includes a first honeycomb mesh disposed on the surfaces of a polyvinyl alcohol film 32 and a cellulose triacetate film 33, and a second honeycomb mesh disposed on the surfaces of an inner thermoplastic polyurethane film 31 and an outer thermoplastic polyurethane film 34. The honeycomb cells of the second honeycomb mesh are different in size from those of the first honeycomb mesh. The honeycomb mesh is formed by ion etching. Thus, the inner first honeycomb mesh and the outer second honeycomb mesh are superimposed on each other, continuously filtering out stray strong light, thereby improving the anti-reflection effect.

[0027] Preferably, the cell size of the second honeycomb mesh is larger than that of the first honeycomb mesh. It is filtered by the outer layer and then further filtered by the inner layer, resulting in stronger permeability.

[0028] In addition, the thickness of the inner thermoplastic polyurethane film 31 and the outer thermoplastic polyurethane film 34 is greater than the sum of the thicknesses of the polyvinyl alcohol film 32 and the triacetate cellulose film 33, thereby enhancing the protection between the outer layer and the film layer.

[0029] The thickness of the nano-honeycomb film layer 30 of the present invention is 300-700μm, ensuring sufficient strength and light transmittance.

[0030] In addition, the functional membrane layer 40 includes one or more of the following: hardening membrane, blue light blocking membrane, red light blocking membrane, UV blocking membrane, and waterproof membrane.

[0031] In summary, the present invention improves the light transmittance of resin lenses, enhances clarity, and reduces interference from stray strong light by setting a nano-honeycomb film layer 20 with a honeycomb structure.

[0032] The foregoing description illustrates 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. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
