| titleOfInvention | Method of forming polarized or photochromic lenses by fusing polycarbonate with other plastic materials |
| abstract | A method for making transparent finished or semi-finished polycarbonate lens first using electrical discharge treatment of the lens surface under certain conditions to improve adhesion of the layers. An electrical discharge is applied to a PVA polarized film surface and to a treatment applied on a PVA film to make a PVA film glued card. By spreading adequate adhesive glue between the PVA film glued card and the polycarbonate lens, one unit lens is formed by photo-chemical reaction technology. Using this unit lens as a back mold I and setting on a front glass mold II, monomer is then poured between these two molds and heated evenly to create a solid one piece lens. A hard coating layer is preferably applied to both concave and convex side of polycarbonate polarized or photochromic lens. The method is particular well suited for casting unique features to bond on polycarbonate lens which normally has a limitation to apply special chemical or parts due to high temperature in the injection molding process. A thermosetting monomer such as photochromic monomer or other transparent monomer can be used. Polycarbonate polarized lens, polycarbonate photochromic lens and polycarbonate photochromic and polarized lens can be cast thereby. The plastic polarized lens, plastic photochromic lens and plastic photochromic polarized lens can be cast by bonding two thermosetting monomer lenses. |
