Abstract:
1. A silicone hydrogel contact lens comprising: a polymeric lens body that is the reaction product of a polymerizable composition comprising a) at least one mono-functional acrylate-containing siloxane monomer having a molecular weight of less than 2,000; b) at least one bi-functional acrylate-containing siloxane monomer having a molecular weight of at least 3,000; c) at least one hydrophilic vinyl-containing monomer; and d) at least one vinyl-containing cross-linking agent, wherein the polymerizable composition has a molar ratio of total amount of mono-functional acrylate-containing siloxane monomer to total amount of bi-functional acrylate-containing siloxane monomer of at least 30:1, respectively, and wherein the silicone hydrogel contact lens provides at least 97% light transmittance between 381 nm to 780 nm as measured in accordance with ISO 18369.
