1.56 Photo Grey,Brown,1.56T6 Photo Grey Lens Progressive

Our progressive photochromic lenses with a refractive index of 1.56 combine high-quality materials with advanced progressive design to provide seamless vision at all distances. Unlike traditional bifocal lenses with sudden power jumps, our progressive lenses offer a smooth transition from distance to intermediate and near vision, eliminating image “jump” and enhancing visual comfort throughout daily activities. The Photo Grey and Photo Brown technologies allow the lenses to automatically adjust their tint in varying light conditions, protecting your eyes from UV and intense sunlight while maintaining clarity indoors.
