Description

Technical Field

[0001] The utility model belongs to the technical field of polarized lenses, and specifically relates to a gradient color polarized resin lens. Background Art

[0002] Polarized lenses are lenses that only allow light of a certain polarization direction in natural light to pass through. Due to its filtering effect, things that pass through the polarizer will become darker. In order to filter out the glaring light from the sun shining on the water, land or snow in the same direction, a special vertical coating is added to the lens, which is called a polarized lens. The effect of polarized lenses is to effectively exclude and filter out scattered light in the light beam, just like the principle of blinds, the light is adjusted to enter the room in the same direction, making the scenery look soft and not dazzling.

[0003] Most of the current polarized lenses are made by stacking a layer of polarizing film on a resin lens. Although the polarizing effect is produced, the polarizing film is mostly brown or gray, which is relatively simple. It is not flexible enough for indoor and outdoor use, and cannot be adjusted, which makes the user experience uncomfortable. Therefore, a polarized lens with gradient color needs to be studied urgently. Utility Model Content

[0024] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, 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 It is a schematic diagram of a gradient color polarized resin lens according to an embodiment of the present utility model.

[0026] As shown in the figure, a gradient color polarized resin lens includes: a PVA polarizing film 10, the thickness of the PVA polarizing film 10 gradually decreases from top to bottom; a resin substrate 20 cured and formed on the front and rear surfaces of the PVA polarizing film 10; a hardening layer 30 dipped on the surface of the resin substrate 20; a gradient color layer 40 spin-coated on the surface of the hardening layer 30, the thickness of the gradient color layer 40 gradually increases from top to bottom; a photocurable protective layer 50 arranged on the surface of the gradient color layer 40; a triacetate cellulose layer 60 plated on the surface of the photocurable protective layer 50; and a high refractive index film layer 70 plated on the surface of the triacetate cellulose layer 60.

[0027] In one embodiment of the utility model, the PVA polarizing film 10 is of a gradual thickness type, that is, a gradient change from one side to the other side. The resin substrate 20 is formed by curing the resin in the rubber ring, and the PVA polarizing film 10 is placed in the middle of the rubber ring. The hardening layer 30 is formed by immersing the resin substrate 20 in a hardening liquid, and preferably, the hardening liquid is an organic silicon solution.

[0028] The gradient color layer 40 is set as a photochromic coating, which can be switched freely indoors and outdoors, eliminating the process of replacing glasses, and its thickness is in the opposite gradient to the PVA polarizing film 10. After the two are superimposed, the anti-glare effect is stronger, the transition is softer, and it is comfortable to wear.

[0029] The photocurable protective layer 50 is spin-coated on the surface of the gradient color layer 40 to improve the protectiveness of the surface film layer and prevent wear. The triacetate cellulose layer 60 enhances its polarization effect. The high refractive index film layer 70 enhances the refractive index and improves the transmittance.

[0030] Preferably, the maximum thickness of the upper side of the PVA polarizing film 10 is 60 μm, and the minimum thickness of the lower side is 25 μm. That is, the thickness of the PVA polarizing film 10 decreases from 60 μm to 25 μm. At the same time, the thickness of the gradient color layer 40 increases from 6 μm to 12 μm, and the thicknesses of the two are reversely gradient, combining polarization and color change, making the transition softer when switching between indoor and outdoor, and more comfortable to wear.

[0031] The high refractive index film layer 70 of the present invention includes, from the inside to the outside, a silicon dioxide film layer, a zirconium dioxide film layer, a silicon dioxide film layer, a zirconium dioxide film layer, a silicon dioxide film layer, and a tin oxide film layer.

[0032] Furthermore, the high refractive index film layer 70 has a thickness of 200-350 μm.

[0033] In summary, the utility model arranges a polarizing film on the inside and spin-coats a gradient color layer on the outside, and the thicknesses of the two are increased and decreased in opposite directions, which can not only provide the gradient color function of polarized lenses, but also make indoor and outdoor switching more comfortable. The triacetate cellulose layer and the high refractive index film layer improve the transmittance of the lens and reduce the interference of stray strong light.
