Description

Technical Field

[0001] The utility model belongs to the technical field of polarizing lenses, and more specifically, relates to a high-refraction polarizing hard film lens. Background Art

[0002] A polarizing lens is a lens that only allows light of a specific polarization direction in natural light to pass through. Due to its light filtering effect, things seen through the polarizing lens will become darker. In order to filter the dazzling light in the horizontal direction when the sun shines on the water surface, land or snow, a special coating in the vertical direction is added to the lens, which is called a polarizing lens. The effect of the polarizing lens is to effectively exclude and filter the scattered light in the light beam. Just like the principle of a shutter curtain, the light is adjusted into collimated light and enters the room, making the scenery look soft and not dazzling.

[0003] Most current polarizing lenses are made by laminating a polarizing film on a resin lens. Although the polarizing effect is produced, the polarizing film itself greatly reduces the refractive index of the lens at the same time, resulting in weakened light transmission enhancement, poor anti-stray strong light effect, and reduced wearing comfort.

[0004] Therefore, there is an urgent need to study a polarizing lens with a high refractive index that can effectively reduce the interference of stray strong light. Summary of the Utility Model

[0005] In view of this, the technical problem to be solved by the utility model is to provide a high-refraction polarizing hard film lens to avoid the trouble of low refractive index and poor anti-stray light effect of conventional polarizing lenses.

[0006] To solve the above technical problem, the utility model discloses a high-refraction polarizing hard film lens, which comprises:

[0009] Resin substrates cured and formed on both sides of the cellulose triacetate film layer;

[0010] A plurality of light diffusion recessed units formed on the front surface of the resin substrate by laser marking, and the light diffusion recessed units are distributed in a ring shape;

[0011] An organosilicon film layer dip-coated on the surface of the resin substrate;

[0012] A high-refractive index film layer group plated on the surface of the organosilicon film layer; and

[0013] An indium tin oxide film layer plated on the surface of the high-refractive index film layer group.

[0014] According to an embodiment of the present utility model, the light diffusion concave unit is set to be a circle with a diameter of 0.15 mm.

[0015] According to an embodiment of the present utility model, the light diffusion concave unit is provided with at least 9 circles.

[0017] According to an embodiment of the present utility model, the thickness of the high refractive index film layer group is 120 - 350 μm.

[0018] Compared with the prior art, the present utility model can obtain the following technical effects:

[0019] By coating a cellulose triacetate film layer on the PVA hard film, the polarization effect is improved; a light diffusion concave unit is formed by laser marking to form light diffusion, effectively reflecting stray light, and at the same time, in cooperation with the high refractive index film layer group, antireflection and light transmittance enhancement are achieved.
