Abstract
Silicone hydrogel contact lenses are formed from the reaction product of a polymerizable composition comprising at least one acrylate-containing siloxane monomer, at least one hydrophilic vinyl-containing monomer, and at least one vinyl-containing cross-linking agent, wherein the polymerizable composition has a molar ratio of total amount of hydrophilic vinyl-containing monomer to total amount of acrylate-containing siloxane monomer of from 5:1 to 30:1, respectively. The silicone hydrogel contact lenses have good manufacturing processability, can be manufactured without the use of alcohol solvents, and have excellent surface wettability.
