Abstract
A mixture used in photochromic devices comprises a photochromic dye and a thermoset adhesive. An optical device using the mixture may include a carrier substrate which may then be secured to another substrate or a lens. Assembly of the carrier substrate and mixture to another substrate and/or lens may be accomplished by thermoforming, lamination, insert molding or the like.
