Abstract
High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise a single aryl hydrophobic monomer as a device forming monomer. In addition, the copolymers comprise a non-polymerizable block copolymer surfactant. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures.
