Abstract
Silicone hydrogel contact lenses having ophthalmically acceptable levels of energy loss are described. The lenses are derived from a polymerizable composition including a first siloxane monomer represented by formula (1): wherein m of formula (1) represents one integer from 3 to 10, n of formula (1) represents one integer from 1 to 10, Rof formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each Rof formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer which is a dual-end methacrylate end-capped polydimethylsiloxane having a number average molecular weight of at least 7,000 daltons. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
