Structure of ultrathin color-changing polarized resin lens

Technical Field

The utility model relates to an optics makes the field, especially relates to a structure of ultra-thin polarisation resin lens that discolours.

Background

In recent years, resin polarized lenses are receiving more and more attention, and are attractive and fashionable, and can effectively protect eyes. The polarizing film has unique optical performance, can effectively filter dazzling rays in the same direction of the sun on water, land or snow, and is suitable for use in maritime activities, skiing, driving or fishing.

At present, in the production process of the polarizer, the manufacturing process of the polarizing film is important and is divided into a dry process and a wet process, the process using the wet process is relatively stable, and the performance of the formed polarizing film is relatively excellent. The most important function of polarization of the polarized light is that of the dye in the polarized light, but the polarized light has advantages and disadvantages, and the color is extremely dangerous when the color is too deep in a tunnel or a garage. Therefore, the research on the polarizer manufacturing structure process using the color-changing material is worthy of attention and attention.
