Abstract
When trifluoroethyl methacrylate, hexafluoroisopropyl methacrylate, pentafluoro-n-propyl methacrylate and/or pentafluoro-n-butyl methacrylate which are fluorine-containing monomers, are added to a conventional monomer mixture for producing a soft contact lens, the resulting soft contact lens has the same optical properties and elasticity as conventional soft contact lenses have, and is very superior to the conventional ones in resistance to deposit and in shape stability.
