POLARIZING LENS SUITABLE FOR SUNGLASSES 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 polariizing lens is disclosed. The method involves glasscasting, 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.
