Described are polymeric matrix compatibilized naphthopyran compounds, examples of which are certain 2H-naphtho[1,2-b]pyrans, 3H-naphtho[2,1-b]pyrans and indeno[2,1-f]naphtho[1,2-b]pyrans each having at least one substituent containing terminal and/or pendant groups selected from hydroxyl, carboxyl, sulfo, sulfono, (meth)acryloxy, 2-(methacryloxy)ethylcarbamyl, epoxy or a mixture thereof. Specific substituents are also present on the naphtho, indeno and/or pyrano portions of the compounds. These compounds may be represented by the following graphic formulae:
Also described are various substrates that contain or that are coated with such compounds. Optically clear articles such as contact lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, are also described.
