A method and apparatus for the stabilizing of napthopyran and spiroxazine photochromic dye in a coating or plastic media is presented. As prolonged exposure to light causes degradation of the photochromic properties of the dyes, a two-tiered layering system is utilized in which a hindered amine stabilizer (HALS) and/or an ultraviolet light (UV) absorber, is placed as a clear coat layer above a bottom layer containing the photochromic dyes. The bottom layer is constructed containing the photochromic dyes by either a coating of a surface of a lens or an imbuing of the photochromic dyes into the lens material, and can further optionally contain a HALS and/or UV blocking compound itself.
