Dual-use photochromic and polarized glasses

Abstract

The invention discloses a pair of dual-use photochromic and polarized glasses, and belongs to the field of lenses. The dual-use photochromic and polarized glasses comprise photochromic layers and polarizers, wherein the photochromic layers are attached to two sides of each polarizer, the dual-use photochromic and polarized glasses are characterized in that the photochromic layers comprise polyvinyl alcohol membranes, zirconium dioxide layers and silicon dioxide layers in sequence, and TAC films are arranged at the outmost layers of the lenses. The dual-use photochromic and polarized glasses disclosed by the invention have the beneficial effects of good refractive indexes, excellent photochromic effects, high wear resistance and high definition, and can solve the problem of momentary strong-light glare.

Description

technical field [0001] The invention relates to a lens, in particular to a color-changing polarized dual-purpose glasses. Background technique [0002] The vision at night is not good. When encountering a vehicle with headlights on, the human eyes are stimulated by the strong light of the headlights, and the pupils automatically contract. Because the pupils have no time to recover, the amount of light entering suddenly decreases, causing dizziness and a phenomenon similar to night blindness, which leads to traffic accidents. . At present, there are many kinds of spectacles on the market, but these spectacles generally have the following defects: poor wear resistance, weak discoloration effect, low definition, and poor night vision. Contents of the invention [0003] In order to solve the above technical problems, the present invention aims to provide a color-changing polarized dual-purpose lens. [0004] Technical scheme of the present invention: [0005] A color-changi...
