Zusammenfassung:The field of the present invention relates to optical-quality parts such as ophthalmic lenses, and particularly to an ophthalmic lens utilizing a polarizing film. An optical-quality part such as an ophthalmic lens is provided having a PET polarizing film integrally bonded thereto and, optionally, a hard coating integrally bonded to either the PET polarizing film or to the optical construct containing the PET polarizing film. In a preferred construction, the lens material or film may be surface treated, either physically and/or chemically, for integrally bonding the film to the lens material. Similarly, in another preferred construction, the film may be physically and/or chemically surface treated for integrally bonding a hard coating to the PET film.
