<p>A soft lens is obtained from a composition comprising, in specified amounts, a monomethacrylate of an alkylene glycol, a fluorine-containing methacrylate, preferably trifluoroethyl methacrylate and/or hexafluoroisopropyl methacrylate, and one or more compounds selected from unsaturated carboxylic acids, monomethacrylates of polyhydric alcohols with three or more hydroxyl groups and alkyl methacrylates. The resulting soft contact lens has the same optical properties and elasticity as conventional soft contact lenses, and is very superior to the conventional ones in resistance to deposit and in shape stability.</p> |
