摘要
The invention relates to transparent photochromic and non-photochromic polymeric organic materials which have a refractive index higher than 1.55, and which are free of optical distortions. The polymeric organic material optionally contains a photochromic coloring agent, a dye, a chain transfer agent, a polymerization initiator or catalyst and a hindered amine light stabilizer. The polymeric organic material is useful in forming an ophthalmic lens, and glazings for automobiles and buildings.
