Abstract: Apparatus for clamping together contact lens molds having a polymerizable liquid monomer disposed therebetween includes a plurality of clamping assemblies each having a linearly translatable shaft member mounted to a contact lens curing table. A common mold clamp release assembly is provided through which each mold clamping assembly passes, thereby ensuring that each mold set is subjected to the same clamping and release profile. Additionally, the amount of clamping force of each clamping assembly may be individually adjusted by way of an adjustable nut mounted to the shaft member which, thereby, controls the amount of force delivered by the shaft member to the contact lens molds being clamped.

Abstract: A packaging system for an intraocular lens and optionally an additive material that can be used to insert a packaged intraocular lens into an eye through a relatively small incision. Methods for inserting an intraocular lens into an eye using such packaging system are within the scope of the present invention.

Abstract: The present invention is directed to an optical device and method for adjustably magnifying the visual displays on the screen of a computer monitor or the like, the invention comprising an adjustable arm for supporting at least one magnifying lens in front of the monitor, which adjustable arm is attached to a stationary support independent of an operator's body. The adjustable arm for supporting the magnifying lens between the viewer of the screen and the screen of the computer monitor is movable in a substantially axial and vertical direction with respect to the computer screen, so that the magnifying lens can be adjustably positioning to a desired position relative to said screen. The invention is especially useful for helping presbyopic computer operators to more clearly see the visual displays on the screen. A second embodiment of the invention further comprises a second lens that can be used to view a document held next to the monitor.

Abstract: Apparatus and method for removing unwanted excess material from a mold section is particularly adapted for removing a monomer ring adhered within a reservoir of a female mold section used to mold a contact lens. The invention involves piercing the monomer ring and rotating the piercing members (e.g., annularly spaced pins) relative to the mold section whereby the monomer ring is sheared from the mold section to which it was adhered while the molded lens is left intact in the mold section.

Abstract: An assembly for fluid processing of an array of ophthalmic lenses includes a support having an array of holes in which an array of lens receptacles are removably positioned for fluid processing. A cover is placed over the support and lenses and include a series of grooves forming fluid passages for the entry and exit of fluid as the assembly is submerged and removed from a bath of processing fluid. The assemblies may be stacked upon each other and placed in a frame for processing batches of lenses at a time.

Abstract: A method for transferring an article from a first receptacle to a second receptacle and, optionally, changing the orientation of the article. A contact lens is initially concave side-down within a well containing solution. By freezing the solution containing the lens-shaped article, the frozen solution with the lens can be conveniently transferred between stations without harming the lens. If necessary, the vessel and lens can be inverted as a unit such that the concave surface of the lens is side-up. The frozen solution melts into a second receptacle well with the lens transferring into the second receptacle. The lens remains concave surface up in the second well.

Abstract: A method and apparatus for practicing the method of making toric contact lenses having a toric axis and ballast axis located on the anterior and posterior surfaces of a lens. Detectable features are formed on the anterior and posterior mold sections corresponding to the location of the toric axis and ballast axis, respectively. An axis alignment tool having detecting means thereon is used to set the mold sections to a known angular position. The desired axial offset is input into a computer which establishes the axial offset between the mold sections.

Abstract: An improved sunglass lens laminate has first and second lens portions joined by an adhesive, wherein the adhesive at least one of (1) an ultraviolet absorber in an amount sufficient to block substantially all solar radiation up to about 400 nm, and (2) a dye to provide selected visible light transmission characteristics to the laminate. In a preferred embodiment, a polarizing film is disposed between two lens portions to form a polarizing sunglass lens laminate.

Abstract: Goggles for use in cold weather, high speed outdoor sports, in conjunction with an insulating hood having a facial opening, are configured to receive the hood around the facial opening, to prevent the hood from obstructing the wearer's vision. The goggles are preferably configured with an outer frame incorporating a lens, an inner frame bearing against the wearer's face, with the outer and inner frames spaced apart to receive the hood at least partially around the facial opening. With the present invention it is possible to remove the insulating hood without displacing the goggles from the wearer's face. In the prior art, it was necessary to remove or otherwise displace the goggles, to allow removal or adjustment of the insulating hood.
