Abstract
An improved method for creating a multi-layered optical lens structure which appears, from an observer's point of view, to have a brushed metal finish, matte finish, decorative pattern, image or logo on the surface of a sunglass lens, but which is optically transparent from a wearer's point of view. The present method for creating a lens structure does not require the use of epoxies or adhesives and allows the lens structure to be made as a polarized lens. The present method offers vast improvements over previously disclosed methods in that it simplifies assembly of the lens structure, allows for greater repeatability, and significantly improves the optical clarity of the final lens structure.
