| titleOfInvention | Soft contact composition and method |
| abstract | A soft contact lens is provided by: pouring an excess amount of an original solution for producing a soft contact lens into a concave mold; placing a convex mold on said concave mold and overflowing the excess of said original solution to thereby uniformly fill said original solution in a space between said concave mold and said convex mold; gelling said original solution between the two molds to form therebetween a lens having a tensile strength of at least about 0.1 kgf/cm 2 ; immersing said lens and said two molds in a liquid to peel said lens from said molds; and extracting the thus-peeled lens via an extraction treatment with water. The "original solution" contains: n a component A selected form the group consisting of monomers and hydrophilic polymers, wherein the monomers yield hydrophilic components when polymerized; a component B, which is a hydrophobic polymer having ethylenic double bonds in its side chains as post-cross-linkable groups, and a solvent C, n the weight ratio of A:B being from about 85:15 to about 55:45 and solvent C being about 5 to 95% by weight. |
