Abstract

Methods are disclosed to injection mold resins, like polycarbonate, to form solid optical lenses. The lenses are ideally suited for use as very thin coating carriers. The method involves closing the mold with a clamp force less than the force exerted on the insert during injection. During injection the mold is allowed to breathe thereby overcoming many of the obstacles associated with injection molding very thin lenses. As the injection pressure subsides, the mold begins to close to perform a coining operation, resulting in a strong, high yield carrier or lens. The so-formed lenses are well suited for laminating into an optical assembly. The assembly can incorporate photochromic functionality.
