Abstract:
1. A silicone hydrogel contact lens comprising: a polymeric lens body that is a reaction product of a polymerizable composition comprising a) at least one acrylate-containing siloxane monomer represented by formula (I): where m is an integer from 3 to 10, n is an integer from 0 to 10, R b) at least one hydrophilic vinyl-containing monomer; and c) at least one vinyl-containing cross-linking agent, wherein the contact lens has an ionoflux of less than 10×10 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.
