Polarized spectacle lens structure and manufacturing method thereof

Abstract

The invention relates to a polarized spectacle lens structure, which comprises a thermoplastic resin lens layer and a polarizing film assembly, wherein the polarizing film assembly consists of a combining film layer, a polarizing film and a protective film layer; the combining film layer and the protective film layer are respectively bonded to two sides of the polarizing film through a bonding agent; and the combining film layer in the polarizing film assembly is combined into a whole with the thermoplastic resin lens layer by an injection molding process. The structure overcomes the defects that a common polarized optical spectacle lens has poor temperature performance, unstable arc bending and easy bouncing and deformation, cannot meet optical refraction standard, and has poor definition of transmittance images and image distortion, and the surface of the common polarized optical spectacle lens is easy to scratch and wear in the prior art; through the design, the positioning of an optical central point is accurate; the combining film layer is combined into a whole with the thermoplastic resin lens layer through the injection molding process, so the peel strength is greatly improved; and the structure has the advantages of stable optical property, clear images, temperature and humidity resistance, no deformation and long service life.

Description

technical field [0001] The invention relates to a polarized spectacle lens structure and a manufacturing method thereof. Background technique [0002] Polarizer is manufactured according to the principle of polarization of light. Its special effect is to effectively eliminate and filter the scattered light in the beam, so that the light can enter the visual image of the eye on the transmission axis on the right track, so that the field of vision is clear and natural, and the scene looks soft and smooth. Not dazzling. Although polarized lenses can filter out many irregular light interferences and avoid glare and glare, if the arc of the lens itself cannot be in the optical standard refractive state, the polarization effect will be weakened, affecting the authenticity of the image. The general polarized lenses on the market are baked and bent, which are soft in texture, poor in temperature resistance, unstable in arc bending, and easy to rebound and deform. Inaccurate diopte...
