MOLDED-IN FILMS FOR SPECTACLE LENSES

摘要

Injection molding of a lens material behind and/or in front of films is described. The films may be of any desired thickness and are pre-inserted into a mold to produce a finished spectacle lens. The films may have been treated or may be configured to offer properties such various tints, abrasion resistance, chemical resistance, weathering, ultra-violet degradation resistance, antifog, polarization, photochromicity, anti-glare, anti-reflection, electrostatic discharge and static dissipation.
