Abstract: Low modulus silicone hydrogel contact lenses 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, R 1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R 2 of formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer, or at least one cross-linking agent, or both. The average modulus of the silicone hydrogel contact lenses is from about 0.30 MPa to about 0.90 MPa when the lenses are fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
