Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lens technology, specifically, it relates to a novel polarized lens. Background Technology
[0002] Polarized lenses are lenses that allow only light of a specific polarization direction to pass through. Due to their filtering effect, they effectively eliminate and filter scattered light from a beam of light, ensuring that light enters the eye along the correct optical axis, resulting in a clear and natural field of vision. Similar to the principle of Venetian blinds, light is adjusted to enter the room in the same direction, naturally making objects appear softer and less glaring. Polarized lenses are best suited for outdoor sports (such as water sports, skiing, or fishing).
[0003] Existing polarized lenses typically only have a polarizing film placed inside the lens ring, then filled with cured resin on both sides to form the lens. Such polarized lenses are relatively thick, have poor light transmission, poor anti-reflection and anti-reflection properties, limited functionality, and are uncomfortable to use. Furthermore, because the polarizing film has smooth edges, it is prone to shifting and detaching during resin filling, causing misalignment, poor adhesion, and affecting subsequent lamination. Utility Model Content
[0004] In view of this, the technical problem to be solved by this utility model is to provide a new type of polarizing lens that avoids the problems of poor anti-reflection properties and easy delamination of the intermediate polarizing film in previous polarizing lenses.
[0005] To solve the above-mentioned technical problems, this utility model discloses a novel polarizing lens, comprising:
[0006] The resin base layer has a PVA polarizing film layer in the middle layer, the edge of the PVA polarizing film layer has a serrated edge, and the surface is covered with a cerium oxide film layer.
[0007] An organosilicon layer dipped onto the surface of a resin substrate;
[0008] A silicon dioxide film deposited on the surface of an organosilicon layer;
[0009] An antireflection film assembly is formed by magnetron sputtering onto the surface of a silicon dioxide film. The antireflection film assembly includes a first magnesium fluoride film layer, a second zirconium dioxide film layer, a third magnesium fluoride film layer, a fourth zirconium dioxide film layer, a fifth magnesium fluoride film layer, and a sixth zirconium dioxide film layer.
[0010] A nano-siloxane film layer with a thickness of 2-5 μm spin-coated onto the surface of an antireflection membrane assembly; and
[0011] A waterproof membrane layer is applied to the surface of a nano-siloxane film layer.
[0012] According to one embodiment of the present invention, the first magnesium fluoride film layer, the third magnesium fluoride film layer, and the fifth magnesium fluoride film layer are low refractive index film layers with a single-layer refractive index of 1.4; the second zirconium dioxide film layer, the fourth zirconium dioxide film layer, and the sixth zirconium dioxide film layer are high refractive index film layers with a single-layer refractive index of 2.0-2.3.
[0013] According to one embodiment of the present invention, the total thickness of the above-mentioned antireflective film group is 450-650 nm.
[0014] According to one embodiment of the present invention, the waterproof membrane layer is configured as a nano-silica membrane layer.
[0015] Compared with the prior art, the present invention can achieve the following technical effects:
[0016] The PVA polarizing film has serrated edges to increase friction after resin curing, preventing it from shifting and peeling off. At the same time, a cerium oxide film is applied to the surface to enhance UV protection. The antireflective coating uses a combination of magnesium fluoride and zirconium dioxide films to improve the refractive index and enhance the antireflective effect. A nano-siloxane film increases the hardness of the lens.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0021] Resin base layer 10, PVA polarizing film layer 20, silicone layer 30, silica film layer 40, antireflective film layer 50, nano-siloxane film layer 60, waterproof film layer 70. Detailed Implementation
[0022] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.
[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a novel polarizing lens according to an embodiment of the present invention.
[0024] As shown in the figure, a novel polarizing lens includes: a resin base layer 10, a PVA polarizing film layer 20 disposed in the middle layer of the resin base layer 10, the PVA polarizing film layer 20 having a serrated edge and a cerium oxide film layer disposed on its surface; an organosilicon layer 30 dipped onto the surface of the resin base layer 10; a silica film layer 40 deposited on the surface of the organosilicon layer 30; an antireflection film assembly 50 magnetron sputtered onto the surface of the silica film layer 40, the antireflection film assembly including a first magnesium fluoride film layer, a second zirconium dioxide film layer, a third magnesium fluoride film layer, a fourth zirconium dioxide film layer, a fifth magnesium fluoride film layer, and a sixth zirconium dioxide film layer; a nano-siloxane film layer 60 spin-coated onto the surface of the antireflection film assembly 50, with a thickness of 2-5 μm; and a waterproof film layer 70 disposed on the surface of the nano-siloxane film layer 60.
[0025] In one embodiment of this utility model, a cerium oxide film is deposited on the surface of the PVA polarizing film layer 20, which can effectively enhance the anti-ultraviolet effect of the film layer. Then, the edge is cut to form a serrated ring. When it is placed on the rubber ring and the resin base layer 10 is cured before and after, the contact friction can be increased to avoid movement. This makes the PVA polarizing film layer 20 more stable after lamination and greatly reduces the risk of delamination caused by movement.
[0026] An organosilicon layer 30 is dip-coated onto the surface of the resin base layer 10 to increase its surface hardness. A silica film layer 40 is pre-coated to reduce reflection. The antireflective coating assembly 50 is made of six layers, alternating between magnesium fluoride and zirconium dioxide films, to improve the lens's antireflective properties. The nano-siloxane film layer 60 is cured by spin coating, further increasing the lens's surface hardness while protecting the antireflective coating assembly. The waterproof film layer 70 is located on the outermost layer, improving the lens's waterproof effect and enhancing its anti-fog properties.
[0027] The first, third, and fifth magnesium fluoride films of this invention are low-refractive-index films, with a single-layer refractive index of 1.4; the second, fourth, and sixth zirconium dioxide films are high-refractive-index films, with a single-layer refractive index of 2.0-2.3. The alternating arrangement of low and high refractive indices significantly improves the lens's refractive index while enhancing its anti-reflective effect. Preferably, the total thickness of the anti-reflective coating group 50 is 450-650 nm.
[0028] In addition, the waterproof membrane layer 70 is set as a nano-silica membrane layer, which can be deposited to improve the surface of the lens and has a wide range of applications.
[0029] In summary, this invention improves the friction after resin curing by setting serrations on the edge of the PVA polarizing film 20, thus preventing the film from shifting and delaminating. At the same time, a cerium oxide film layer is set on the surface to enhance the protection against ultraviolet radiation. The antireflective film layer uses a combination of magnesium fluoride film layer and zirconium dioxide film layer to improve the refractive index and enhance the antireflective effect. The nano-siloxane film layer improves the hardness of the lens.

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.
