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.
