Plastics for ophthalmic lenses comprising a polymer mixture of (A) an unsaturated polyester resin, (B) a monomer of formula (I), (C) optionally a vinyl, an acrylate monomer, or another monomer or their mixtures, and (D) a catalyst system producing free radicals. This polymerizable plastic material makes it possible to produce ophthalmic lenses having superior properties, including a refractive index which reduces the amount of material necessary for corrections. |
