First Claim
Patent Images
1. A silicone hydrogel soft contact lens obtained by a process comprising:
- polymerizing a mixed solution which comprises a first silicone monomer comprising a hydroxyl group or polyethylene glycol group in a molecular structure thereof and glycerol mono(meth)acrylate in a both-face cast mold, which has a wettable surface without applying an additional treatment to improve surface water wettability of a surface to a lens-shaped material after polymerization.

Abstract
Provided is a silicone hydrogel soft contact lens obtained by curing in a double-sided casting mold, a liquid mixture including glycerol mono(meth)acrylate and at least one type of silicone monomer having at least one hydroxyl group or polyethylene glycol group in the molecular structure thereof, the silicone hydrogel soft contact lens having a wettable surface without a polymerized lens-shaped material being subjected to post-processing to improve the water wetting properties of a surface thereof.
