Manufacturing method of tempered glass resin polarized glasses

Abstract

The invention provides a manufacturing method of tempered glass resin polarized glasses. The pair of tempered glass resin polarized glasses comprises a glasses framework and lenses, wherein each lens comprises a front glass optical thin sheet, a rear resin optical thin sheet and a polarized film flat sheet; the middle region of the front glass optical thin sheet is polished to form a concave region and the rear resin optical thin sheet is tightly embedded into the concave region; and the polarized film flat sheet is stuck between a rear concave surface of the front glass optical thin sheet and a front convex surface of the rear resin optical thin sheet to form tempered glass resin polarized lenses. Compared with existing tempered glass polarized pieces, the weight of the prepared tempered glass resin polarized lenses is reduced by 25-35% so that the comfort is greatly improved; compared with existing resin polarized sheets, the polarization rate is improved and the polarization effect is improved; the lenses are not easy to deform when being inserted into the glasses framework and being used in a subsequent utilization process; and the manufacturing method has strong controllability, is suitable for production line type production and is widely suitable for popularization and application, and the production efficiency and the finished-product yield are improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a method for manufacturing tempered glass resin polarized glasses. Background technique [0002] Polarized lenses are manufactured according to the principle of polarization of light, which can block the scattered reflected light in natural light, glare and irregular reflected light of objects, so as to avoid eye discomfort and safety hazards. Wear it when you are in the sun, or playing in a lake with strong waves, or in a glass building, or driving on a smooth road, to filter the strong light reflection and avoid inconvenience to people's life, travel, especially driving in summer . [0003] With the rapid development of science and technology, light pollution is becoming more and more serious, and all kinds of dazzling light bring discomfort to people. Polarized lenses can alleviate light pollution. Polarized lenses are made according to the principle of light polariza...

Problems solved by technology

These two kinds of polarized lenses are lenses with a deep base color, which cannot meet people’s requirements for night, rainy and all-weather use. At present, they can only be used outdoors on sunny days with sufficient light. Unable to popularize and promote applications in the learning environment

[0004] At present, glass polarized lenses and resin polarized lenses are commonly used. Among them, the manufacturing process of glass polarized lenses is more cumbersome than that of resin polarized lenses, and the weight of glass polarized lenses is relatively heavy, which is not comfortable for people to wear. High polarizing rate has good polarizing effect, and is wear-resistant and scratch-resistant; although resin polarized lenses are light in weight, their polarizing effect is not as good as that of glass, and they are easy to be scratched and deformed when framing; therefore, it is necessary to develop an operability Manufacturing method of toughened glass resin polarized glasses with high wear resistance, scratch resistance, light weight, high polarization rate and not easily deformed
