Contact Lenses

Silicone materials are incorporated in contact lenses to enhance oxygen permeability and improve comfort; however, pure silicone backbone lenses are not used due to wetting dehydration, mechanical, and optical problems. Gelest is developing new silicone materials to produce wettable silicone hydrogels with increased formulation flexibility for next generation performance additives.
