Spin Coating Photochromic
Photochromic lenses use photochromic compounds reacting to UV light for darkening, providing UV protection. They return to a clear state indoors. Compared with mass photochromic, our spin coating technology can greatly reduce the time it takes for you to change color and fade, giving you a better visual experience.
