    Abstract: The present method for coating a Fresnel lens blank comprises providing an uncoated Fresnel lens blank (10) having a structure surface (13) and a non- structured surface (12), providing a transparent mold part (14) having molding surface substantially matching the base curvature of the Fresnel lens, depositing a metered quantity of coating resin (17) between the molding surface and the structured surface of the Fresnel lens, applying pressure between the Fresnel lens and the mold part while maintaining the distance between the molding surface and the structure surface so that the thickness of the coating is greater than 1.5 times the Fresnel structural height of the structured surface and less than 5 times of the Fresnel structure height of the structured surface and curing the resin coating in situ by directing the incident UV radiation at the Fresnel lens. A double coating may be employed for obtaining both higher optical power and better mechanical properties.

    Abstract: Method for fabricating a Fresnel lens or other lens having a structured surface such as refractive and/or diffractive bi-focal or other multi-focal lenses includes press-coating the structured surface with a low or very low refractive index coating material. The coating is sufficient thick to adequately cover the structured surface so that a smooth coating surface with good optical properties is obtained, in the case of a Fresnel structure a thickness greater than 1.5 times and less than 5 times the Fresnel structure height, and is cured in situ. A film, e.g., of PET, PC or PU or a film stack, e.g. a TAC/PVA/TAC film stack is prepared and a heat melting adhesive is applied to the side of the film or film stack to be brought into contact the coated structured surface of the lens blank. The film or film stack is then laminated to the cured coating.

    Abstract: A method for laminating a film on to an optical article and a bi-layer adhesive for use in the method. The bi-layer adhesive includes a latex adhesive layer or a specific silane adhesive and an HMA layer sequentially disposed on the film and dried to form a solid layer of uniform thinness throughout to provide optical quality. Various types of films may be employed to provide an optical function. Following optional pre-treatment steps, the adhesives are coated on to the film. An optical hot press technique is used to deliver heat and pressure over a short period of time to form a functionally-enhanced optical article with high adhesive strength.
