Methods for improved adhesion of an optical coating to a polarizing film incorporated onto an optical-quality plastic construct are disclosed. Preferred methods include treating a surface of the film by mechanical and/or chemical means and applying an optical coating to the treated film for effecting a coated, polarized optical-quality plastic part. Such mechanical and chemical means include exposing the polarizing film to a caustic solution at a concentration greater than or equal to 10%, roughening the surface of the film in a uniform manner, and utilizing plasma exposure to peen the surface and then chemically modify it. A particularly preferred technique involves uniform physical roughening, namely, forming grooves having a substantially uniform direction substantially aligned with the axis of light absorption, exposing this roughened surface to a caustic solution having a concentration of 10% or greater, and then dipping the roughened surface into an overcoat solution and withdrawing it substantially perpendicular to the direction of the grooves.

An eyewear lens provides for selective spectral performance in response to varying light conditions, including both changes in intensity and spectral distribution. The lens responds selectively to both ultraviolet and visible light, and exhibits different spectral transmittance characteristics under different lighting conditions, to provide for better vision for a wearer. In addition to this active response, the lens also may include a polarizer to further control light and to minimize the glare that interferes with clear vision.

A method is disclosed for pre-conditioning inserts for improved replication during injection molding. The pre-conditioned inserts provide improved bonding with the injection-material and improved replication of complex molding surfaces. The pre-conditioning of the inserts comprises placing the insert in position against the molding surface, followed by heat-soaking the insert. Heat-soaking can be accomplished using infrared energy, preferably broadband infrared energy or energy that is preferentially absorbed by the insert.

The present invention is embodied in ophthalmic lenses having a first lens surface that is described by a continuous, gradual increase in optical power that proceeds without inflection points of discontinuities across substantially the entire useable optical area of this lens surface, and an opposite surface of the lens configured to cooperate with the power gradation of the first surface to provide a desired prescription, including at least one stabilized area of optical power. The power gradation of the first surface increases from one edge of the useable area to substantially the opposite edge, and may increase according to linear or non-linear relationships. In another preferred embodiment, the two lens surfaces cooperate to create two stabilized areas of optical power, for a prescription with near-viewing and distance-viewing values.
