Abstract: An anti-reflective, anti-static coating, optical articles employing such a coating, and methods of forming the same. The coating formed of alternating layers of low, mid, and/or high refractive index oxide materials and one or more layers of electrically conductive, substantially non-oxide forms of the same materials employed to form the alternating layers of low, mid, and/or high refractive index oxide materials.
Abstract: A polarizing optical article formed by selectively applying a conductive coating to a portion of a structured surface formed of a series of linear peaks and valleys.
Abstract: The present invention relates to a polarization filter for ophthalmic lenses. The polarization filter comprises a mesogen layer coated onto a retardation film, either directly or through an adhesive layer. The present invention further discloses that the polarization filter formed by employing a thin film or sheet, having a defined level of retardation between the light source and the mesogen layer, for example, a cholesteric mesogen layer, the multilayered laminate structure demonstrates linear polarization of the light transmitted through the mesogen laminate structure, and, hence, can be used in ophthalmic lenses, e.g. spectacle or eyeglass lenses. The polarization filter enhances the performance by allowing transmission of the polarization filter closer to the theoretical maximum transmission.

Abstract: A semi-finished ophthalmic lens for formation of a plurality of different finished ophthalmic lenses requiring reduced amounts of lens material to be removed for formation of the finished ophthalmic lenses and reduced rates of departure of a surfacing tool and methods of making same. Lens material is reduced by providing first and second surfaces that have different optical powers, the second optical surface having a second curve that approximates second optical surfaces of a plurality of finished ophthalmic lenses at coordinates at which lenses of the plurality of finished ophthalmic lenses have maximum thicknesses.

Abstract: A photochromic polyurethane laminate wherein the photochromic polyurethane layer of the laminate has been crosslinked with an isocyanate-active prepolymer using a crosslinking agent. The crosslinking agent is formulated to have at least three functional groups that are reactive with functional groups of the polyurethane or of the isocyanate-active prepolymer. A method of making the photochromic polyurethane laminate includes steps of causing the crosslinking.
