  • Shaped plastic light-polarizing lens and method of making same
    Patent number: 5434707
    Abstract: Plastic lenses having substantially no optical power and a light-polarizing layer therein are prepared by shaping composite laminate of the light-polarizing layer between opposed sheets of thermoplastic material by heating and pressing the laminate between opposed shaping molds (platens), the platens having predetermined radii of curvature for the production of a lens having substantially no optical power. Shaping is effected under conditions of heating and pressing sufficient to cause flow of the thermoplastic sheets and conformation thereof to the respective curvatures of the forming surfaces of the platens. The lenses are especially suited as sunglass lenses for spectacles.
