Abstract
Ophthalmic lens molds made from one or more thermoplastic polymer having a low level of UV light transmittance (UV % T) ophthalmic lenses including silicone hydrogel contact lenses molded using these thermoplastic polymer having low UV % T, and methods of manufacturing ophthalmic lenses by cast molding a polymerizable composition in mold members formed of these thermoplastic polymers having low UV % T and curing the polymerizable composition using UV light are described.
