Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarized lens technology, specifically to a high-refractive-index 1.61 soft film 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, things appear darker when you wear them. They are typically used for outdoor activities such as water sports, skiing, fishing, and driving.
[0003] Polarizing lenses effectively eliminate and filter scattered light from a beam of light, allowing light to enter the eye along the correct transmission axis. The imagery makes the view clear and natural, much like the principle of Venetian blinds, where light is adjusted to enter the room in the same direction, naturally making the scenery look soft and not glaring.
[0004] However, existing polarized lenses still have several shortcomings: 1. Light is reflected after passing through the lens surface, resulting in low light transmittance. In darker environments, such as at night, this can affect the customer experience; 2. They lack anti-fog effect. When worn in low temperatures, the fog droplets formed by exhaled breath can affect vision; 3. They have poor impact resistance and are easily broken or deformed. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a high-refractive-index 1.61 soft film polarizing lens.
[0006] Technical solution
[0007] A high-refractive-index 1.61 soft-film polarized lens includes a lens substrate and a polarizing film layer. The polarizing film layer is disposed on the convex side of the lens substrate. A first soft rubber buffer layer is disposed between the polarizing film layer and the lens substrate. A second soft rubber buffer layer is disposed above the polarizing film layer. A hard resin layer is disposed above the second soft rubber buffer layer. An anti-blue light film layer, an anti-ultraviolet film layer, and an anti-reflective film layer are disposed above the hard resin layer. A hardening layer is disposed above the anti-reflective film layer. An anti-fog coating is spin-coated on the upper surface of the hardening layer and the concave surface of the lens substrate.
[0008] Furthermore, the hardening layer contains silver halide as a color-changing agent and copper oxide microcrystals as a catalyst.
[0009] Furthermore, the polarizing film layer has a three-layer structure, which is composed of a middle polarizing PVA film layer and two TAC film layers on both sides.
[0010] Furthermore, the antireflective coating is composed of alternating layers of zirconium dioxide and silicon dioxide.
[0011] Furthermore, the lens substrate is made of PC or TR material.
[0012] Furthermore, the first and second soft rubber buffer layers are made of UV-cured soft rubber.
[0013] Furthermore, the hard resin layer is made of epoxy resin, and the pencil's softness is 1B to 3B.
[0014] Furthermore, the anti-fog coating is a hydrophilic polymer, such as a hydrophilic acrylic copolymer.
[0015] Beneficial effects:
[0016] This invention provides a high-refractive-index 1.61 soft-film polarized lens. By incorporating multiple layers of soft rubber buffer, it effectively resists impact and reduces the risk of breakage and deformation. The top and bottom layers of the polarized lens are equipped with anti-fog coatings to prevent fogging and ensure a clear view. An anti-reflective coating further enhances light transmittance, providing a better user experience. Additionally, a hardening layer increases scratch resistance and absorbs ultraviolet and blue light, reducing the harmful effects of light on the eyes and skin. This hardening layer can also change color to reduce light transmission under strong light. Attached Figure Description

Detailed Implementation
[0019] The present invention will now be described in detail with reference to the accompanying drawings. Specific implementation examples:
[0021] like Figure 1As shown, a high-refractive-index 1.61 soft-film polarized lens includes a lens substrate 1 and a polarizing film layer 2. The polarizing film layer 2 is disposed on the convex side of the lens substrate 1. A first soft rubber buffer layer 3 is disposed between the polarizing film layer 2 and the lens substrate 1. A second soft rubber buffer layer 4 is disposed above the polarizing film layer 2. A hard resin layer 5 is disposed above the second soft rubber buffer layer 4. An anti-blue light film layer 6, an anti-ultraviolet film layer 7, and an anti-reflective film layer 8 are disposed above the hard resin layer 5. A hardening layer 9 is disposed above the anti-reflective film layer 8. An anti-fog coating 10 is spin-coated onto the upper surface of the hardening layer 9 and the concave surface of the lens substrate 1. It should be noted that... Figure 1 The thickness of each layer shown is for illustrative purposes only and does not represent the actual thickness ratio.
[0022] The polarized lens in this embodiment has an anti-fog coating 10 spun onto both the upper and lower surfaces, effectively preventing fogging and making it suitable for use in cold weather. The anti-reflective coating 8 increases light transmittance, making it suitable for use at night when overall light is weak but localized glare needs to be avoided, such as when driving at night to prevent glare from strong lights. It can also be used on some vehicle windshields to increase light transmittance while driving and prevent glare from other vehicle headlights or streetlights. Additionally, multiple layers of soft rubber cushioning absorb impact, increasing impact resistance and preventing lens breakage and deformation. It also provides blue light and UV protection, and the surface hardening layer 9 further enhances scratch resistance.
[0023] Preferably, the hardening layer 9 contains silver halide as a color-changing agent and copper oxide microcrystals as a catalyst. Under ultraviolet light, the silver halide decomposes to form silver, blocking the light. Positioned in front of the UV-protective film 7, it responds quickly, causing the hardening layer 9 to change color. This further enhances the anti-glare properties compared to the polarizing film layer 2, making it suitable for strong outdoor light interference. The addition of inorganic particles also helps increase the surface hardness of the hardening layer, improving scratch resistance.
[0024] like Figure 2 As shown, the polarizing film layer 2 has a three-layer structure, composed of a middle polarizing PVA film layer 201 and two TAC film layers 202 on both sides. The PVA film is obtained by iodide bromination and directional stretching. The TAC film is then laminated onto the polarizing PVA film using a casting and bonding method. The connection between the TAC film and the polarizing PVA film is more compact, and the TAC film has excellent properties to prevent shrinkage of the polarizing PVA film, thereby improving the polarization and light intensity, and making the structure more stable.
[0025] like Figure 3 As shown, the antireflective coating 8 is composed of alternating layers of zirconium dioxide film 801 and silicon dioxide film 802. Zirconium dioxide is a high refractive index material, while silicon dioxide is a low refractive index material. The alternating design can achieve a wider antireflection band.
[0026] Preferably, the lens substrate 1 is made of PC or TR material. It has high light transmittance (1.61), allowing for general or high-pressure bending and forming to achieve the desired optical properties. PC and TR materials offer good stability, are not easily affected by moisture, have excellent temperature resistance, and good elasticity, enabling them to maintain the dimensions and curvature during production. They also exhibit excellent optical performance and impact resistance.
[0027] Preferably, the first soft rubber buffer layer 3 and the second soft rubber buffer layer 4 are made of UV soft rubber, which has strong adhesion and elasticity, and can be used as elastic buffer to prevent shock and drop.
[0028] Preferably, the hard resin layer 5 is made of epoxy resin, and the pencil softness is 1B to 3B. The hard resin layer 5 and the lens substrate 1 form a clamping structure, which can prevent the film layer between the two from deforming.
[0029] Preferably, the anti-fog coating 10 is a hydrophilic polymer, such as a hydrophilic acrylic copolymer. With a water contact angle of approximately 5°, the fog droplets can quickly flatten, reducing light scattering.
[0030] Figure 4 This is a schematic diagram of the structure of one specification of polarizing lens in this embodiment. Only the position of polarizing film layer 2 is shown in the figure. The film thickness is 0.035mm, the distance from the top surface of the polarizing lens is 0.8mm, and the diameter of the polarizing lens is 75mm.
[0031] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
