Photochromic Polarized Lenses

This new item is developed based on our polycarbonate polarized lens technology. Our photochromic dye is spread in the polycarbonate layer, not coated on the surface of the lenses. It means the photochromic function will not be destroyed by the scratches or any damages on lens surface.

Different from other photochromic Polarized lenses in the market, our base lenses are thermoformed polycarbonate polarized lenses, which means the price is cheaper than Injection Molded polycarbonate lenses, NXT or other urethane based photochromic polarized lenses. This product allows you to provide your customers the latest sunglass lens technology with the reasonable price level.
