Abstract: A method for processing a cured contact lens wherein the contact lens is hydrated while retained in the mold cavity in which it was cast. The lens is released from the mold with cured excess lens material remaining with the mold.

Abstract: The present invention is directed to methods and apparatus for collecting and pooling the contents of a multiple number of individual sample containers, the apparatus comprising an autoclavable collection bottle capped with a closure-adaptor means having at least one passageway for transfering the fluid contents of the sample containers into the collection bottle. In one embodiment of the invention, the closure-adaptor means comprises a plastic retainer ring for securely holding a flanged cylindrical stopper in which the above-mentioned passageway is formed. Still another aspect of the invention relates to a method of sample testing comprising collecting a pooled sample of a solution or gel, inoculating and/or filtering the pooled sample, and analyzing the inoculated sample or the filter retentate for microbial contamination.

Abstract: A stand for use with a magnifying device having a base plate, a supporting member and a magnifier holder. The stand may hold the magnifier at two different angles to the viewing surface as well as fold into a flat, compact package. The magnifier may be a retractable, lighted magnifier.

Abstract: Low water siloxane macromonomer are disclosed. This macromonomer can be copolymerized with unsaturated silicone containing monomers to prepare polymeric materials useful as biomedical devices. These macromonomers are particularly suited for soft contact lens applications.

Abstract: Low water silicone-containing elastomers are based on a hydroxy- or amino-terminated prepolymer derived from an ethylenically unsaturated silicon-containing monomer, and at least one monomer reactive with hydroxyl- or amino-functional radicals of the prepolymer. The elastomers are especially useful as contact lens materials.

Abstract: A method of injection molding contact lens molds for cast molding contact lenses having a rotationally asymmetric lens surface, and apparatus for carrying out the method, are disclosed.

Abstract: A method for transferring a lens-shaped article from a first support to a centered position on a second support employs a transfer tool having a slideable plunger and plunger sleeve that cooperates with the first and second support to ensure that the article is oriented in a desired manner when transferred.

Abstract: An improved sunglass lens laminate having first and second lens portions joined by an adhesive, wherein the adhesive contains sufficient ultraviolet absorber to block substantially all of the UVA radiation in sunlight. In a preferred embodiment, a polarizing film is disposed between two lens portions to form a polarizing sunglass lens laminate.

Abstract: A hinge, particularly for rotatably coupling two parts of a pair of eyeglasses preferably made of plastics. The hinge is constituted by at least one first element, which merely allows the mutual positioning of the two components, and by at least one separate second element, which allows the mutual and temporary rotary coupling of the two parts.
