tritan(TR18) Lens
The new generation Copolyester(no bisphenol A) developed by Eastman company was originally to replace PC material. After it was widely applied to the field of spectacle lenses known the properties were basically similar with nylon lens. High light transmittance, excellent impact resistance strength. Much more advantages in price and cost compared with nylon. For the drilling and cracking problem in the industry, our company has a good improvement method to overcome it so we believe Tritan will become one of the leading lens in the glasses field in very soon future

Crystal star directing imported Eastman company raw material matched with the standard intelligent & automatic dying hard coating advanced production line in free dust space to supply the high-quality TR18 sun lenses
