Abstract: A light polarizing spectacle lens including a lens body and a light polarizing film embedded in the lens body. The lens body is made from a resin mixture comprising a pregelled monomer of about 65 to 75 weight percent of the mixture, a conventional monomer of about 25 to 35 weight percent of the mixture, and isopropyl carbonate of about 2.7 to 2.9 weight percent of the mixture. The polarizing film is in the form of a wafer dried at approximately 140.degree. F. to 160.degree. F. for about 2-12 hours.

Abstract: A process for making a light polarizing spectacle lens and the light polarizing spectacle lens product. The process includes drying a polarizing film at approximately 140-160.degree. F. for approximately 2-2 hours in order to drive out any transport media from the polarizing film. The process next includes forming the dried polarizing film into a wafer, curving the wafer at a specific time and temperature range, notching the curved wafer to align with a pair of gasket protrusions, and positioning the wafer within a lens mold. The process additionally includes adding a lens resin to the lens mold containing the wafer so that the lens resin includes a pregelled monomer in a weight percent of 65-75% and curing the lens.

Abstract: A progressive addition lens is provided having a wide transition corridor and an improved balance between astigmatism and distortion in the field of peripheral vision to provide a wide, distortion-free clear view. This is achieved by employing a cosine function in blending the transition corridor with the peripheral area.

Abstract: The lens of the present invention is a progressive power lens having a top portion for distance viewing and a bottom portion for close-up vision with a continuous transition corridor between the top and bottom portions. The lens is characterized by having a very wide transition corridor as contrasted with prior art lenses.
