Abstract: The invention relates to an improvement for applying a layered structure (1) onto a convex surface of a lens (10). After thermoforming the layered structure, a curvature direction of the layered structure is inverted. The structure is then applied on the lens surface by continuously pushing the structure (1) against the lens surface, starting from a contact point between a convex surface of the structure and the convex surface of the lens. The curvature direction of the layered structure is then inverted again, so that it recovers the curvature direction that resulted from thermoforming. Stresses within the layered structure are then reduced, and the structure can be assembled with the lens without defects.

Abstract: A method for molding a plastic ophthalmic lens which comprises introducing a liquid polymerizable composition in a molding cavity of a two-piece mold through a filling nozzle in flow communication with the upper half of the molding cavity and spaced apart from the central vertical axis of the molding cavity up to the time the lower half of the molding cavity is filled. Then, tilting the mold to bring the filling in register with the central axis of the molding cavity and achieving full filling of the molding cavity. Thereafter, polymerizing the composition and recovering the lens.

Abstract: Internal mold release compositions for molding polyurethane and polythiourethane is disclosed herein. The composition includes a mixture of: (a) a mono C2-C6 alkyl phosphate; (b) a di C2-C6 alkyl phosphate, wherein the alkyl groups of the di-alkyl phosphate may be the same or different, and wherein the alkyl groups of the mono- and di-alkyl phosphate may be the same or different; and (c) a C7-C18 mono- and/or di-alkyl phosphate. Also disclosed is a polymerizable composition which includes (a) one or more monomers containing two or more isocyanate groups; (b) one or more monomers containing two or more functional groups selected from a thiol group and a hydroxyl group; (c) a mixture of a mono- C2-C6 alkyl phosphate and a di- C2-C6 alkyl phosphate, wherein the alkyl groups of the di-alkyl phosphate may be the same or different and wherein the alkyl groups of the mono- and di-alkyl phosphate mixture may be the same or different, wherein the mono- C2-C6 alkyl phosphate is present in an amount of >/=20 wt %, based on the total weight of the mixture of the mono- C2-C6 alkyl phosphate and the di- C2-C6 alkyl phosphate. The composition can also optionally include the C7-C18 mono- and/or di-alkyl phosphate.

Abstract: La invención se refiere a una mejoría para aplicar una estructura (1) estratificada sobre una superficie convexa de una lente (10). Después de termoformar la estructura estratificada, se invierte una dirección de curvatura de la estructura estratificada. La estructura se aplica entonces sobre la superficie de la lente empujando continuamente la estructura (1) contra la superficie de la lente, empezando desde un punto de contacto entre una superficie convexa de la estructura y la superficie convexa de la lente. Se invierte entonces otra vez la dirección de curvatura de la estructura estratificada, de manera que recupera la dirección de curvatura que resultó del termoformado. Se reducen entonces las tensiones dentro de la estructura estratificada, y la estructura puede ser ensamblada con la lente sin defectos.

Abstract: A method for making an organic glass lens or lens blank which comprises providing a two-piece mold defining a molding cavity having a vertical axis which is part of a fixed reference system comprising said vertical axis and a horizontal axis which intersects at the center of the mold, a liquid tight annular closure member disposed at the periphery of the mold pieces for maintaining the two mold pieces and closing the molding cavity, wherein the annular closure member comprises at least a portion thereof made of a material that is initially gas permeable but becomes gas impermeable when in contact with a liquid polymerizable composition.
