At the same time, the material is not easy to change color (common resin lenses are easy to yellow);

(2) lighter quality, currently the lightest type of optical lens;

If there is no technical problem with the lens, the weight of the lens will be about 30% lighter than the ordinary resin piece, and about 50% lighter than the glass piece.

(3) PC is made of viscous material with strong toughness, which is not easy to break, and has strong impact resistance, which is 10 times stronger than that of resin sheet and more than 60 times stronger than that of glass sheet.

(4) due to the characteristics of high refractive index and light weight, various multi-functional and multi-purpose PC lenses are being continuously introduced.To meet the wearer's physiological, protective and other comprehensive needs;

Zhengshun polycarbonate solid sheet has high impact strength ,highlight transmission and UV protection.it is the best choose for glass lens.
