Abstract: Curved lenses and methods for making curved lenses are described. One embodiment of a method of making a curved lens includes curving a lens blank made of a linear polarizer layer laminated together with a plurality of polymeric layers. The lens blank is curved by heating and pressing the lens blank between a curved rigid member and a flexible member at a pressure and maintaining the pressure for a time sufficient to allow the lens blank to conform to the shape of the curved rigid member. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.

Abstract: The invention is for an improved hinge for pivotably connecting an eyeglass temple piece to an eyeglass frame, which permits a stable positioning of the temple piece in a folded or closed position in order to conveniently store the eyeglasses and a stable positioning of the temple piece into a normal open position for wearer use of the frame and which permits still further elastic movement of the temple piece beyond the normal open position without damage to the frames or hinge. The improved hinge includes a rod-shaped slide which is slideably mounted in a seat provided in the end portion of the temple piece and which protrudes from the seat. A hole is formed in the slide which extends coaxially in the slide over a predetermined depth from its protruding end. A slot is formed in the slide which extends longitudinally in the slide over a predetermined length from its protruding end. The predetermined length of the slot is less than the depth of the hole in the slide and the slot debouches in that hole.

Abstract: The method for producing articles from thermosetting resins, more particularly articles having a complex, variable shape such as spectacle frames, comprising bottom casting liquid thermosetting resin into a mold and causing the resin to set in a field of centrifugal force.
