ABSTRACT:
The invention provides techniques for making polycarbonate or plastic lenses. In one exemplary embodiment, for example, an electrical discharge is applied to a polarized film surface and a treatment applied on the polarized film to make a glue card. An adequate amount of adhesive glue is spread between the polarized film glue card and a polycarbonate lens, and a one-unit lens is formed by photochemical reaction technology. Thermosetting monomer is poured between the unit lens and a glass mold, and heated evenly to create a solid one-piece lens. The thermosetting monomer may be a photochromic or transparent monomer. These or substantially similar techniques may be used to produce polycarbonate polarized lenses, polycarbonate photochromic lenses, polycarbonate photochromic polarized lenses, plastic polarized lenses, plastic photochromic lenses, and plastic photochromic polarized lenses.
