Silicone hydrogel contact lenses that are derived from a polymerizable composition including a first siloxane monomer represented by formula (3): n n n n n n n n n n n n wherein m of formula (3) represents one integer from 3 to 10, n of formula (3) represents one integer from 1 to 10, R 1 of formula (3) is an alkyl group having from 1 to 4 carbon atoms, and each R 2 of formula (3) is independently either a hydrogen atom or a methyl group; and at least one vinyl ether-containing cross-linking agent are described. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described. In one example, the batches of silicone hydrogel contact lenses are dimensionally stable, and the method of making is a method of making dimensionally stable silicone hydrogel contact lenses. |
