Polarized lens formed by injection/coining injection molding process |
摘要 |
A polarized lens formed by an injection/coining injection molding process is disclosed. The polarized lens includes a polarizing insert formed from a polarizer sandwiched between two layers of cellulosic material. The polarizing insert is surrounded by high-impact polymer formed by a two-step injection/coining process of injection molding that results in minimal stress in the lens.
