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 lens, comprising: providing a vertically-oriented molding cavity (40) having a top (30) and a bottom (32) and being defined by at least (a) a first mold piece (14) having a concave surface, (b) a second mold piece (12) having a convex surface, and (c) a closure member (16) disposed around and attached to the first and second mold pieces, a sealing material (18) having self-sealing properties being connected to the closure member (16) and positioned near the bottom (32); puncturing the sealing material (18) and the closure member (16) near the bottom (32), thereby creating an opening in the sealing material (18) having a size that reduces after the instrument (50) is retracted; introducing a polymerizable composition into the cavity (40) through an instrument (50), retracting said instrument and polymerizing the polymerizable composition to form a lens.

Abstract: A method for casting plastic lenses is disclosed in which lens forming materials including at least one liquid monomer and at least one photosensitive initiator are injected into a mold (8,48). The lens forming materials in the mold are subjected to ultraviolet light. The mold assembly is cooled in a liquid cooling bath (38). The temperature of the lens forming material within the mold is monitored, and the ultraviolet light is turned off when the temperature reaches a predetermined upper set point temperature. The ultraviolet light is turned on again when the temperature falls to a predetermined lower set point temperature. The process can be performed automatically with a programmable process control, which monitors the temperature, compares the temperature to the predetermined set point temperature, and turns the ultraviolet light on and off according to the results of the comparison.

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.
