Polarizing prescription lenses and method of making

摘要

Apparatus and a method for adhering a flexible soft polarizing film to a curved surface, such as the convex surface of a prescription eyeglass to be made into a polarizing lens is disclosed. The method involves glass-casting, and preformation of the film in a manner calculated to have a minimum hardening/drying effect. Air is excluded during lamination without the need for a vacuum and the attendant complications.
