Methods for Manufacturing Laminated Film and Articles Made Therefrom

摘要

The present invention relates to methods of manufacturing laminated film and article made therefrom, such as eyeshields, faceshields and lenses. Specifically, the methods of the present invention laminate a film or plastic layer with a protective layer via an invention laminating process. The process may further be utilized to add materials, such as, for example, photochromic material to optically transparent material. Preferably, photochromic material is adhered to optically transparent material in a hot molding process.
