They return to lighten shade when no longer exposed to ultraviolet radiations. Photochromic lenses may be made of glass or plastic. Glass photochromic lenses have an embedding of microcrystalline silver halides molecules in glass substrate, whereas plastic photochromic lenses are made of organic photochromic molecules. Market for photochromic lenses is growing due the increasing levels of ultraviolet radiations in the atmosphere resulting in increased prevalence of eye diseases.
