Abstract
The present invention describes composite constructed ophthalmic lenses comprising at least two layers of optical materials that provide a composite structure over a practical vision zone of the lens product, are identifiably disparate from each other, and are integrally bonded to each other such that the adhesion of the first layer to the second layer exceeds a ranking of at least 3 when tested according to specified tests. In a preferred embodiment, one layer comprises thermoplastic polycarbonate and the second layer comprises polyurea-urethane material and one or more additives. The first layer may comprise a polarizer. The composite lens may also comprise coatings or other components.
