PROCESS FOR APPLYING A FILM STRUCTURE ONTO A LENS BLANK |
摘要 |
A process for applying a film structure onto a lens blank is improved by implementing a wedge piece when the film structure is pressed against the lens blank using a resilient cushion. The wedge piece forces the film structure to conform more tightly to the lens blank within a depression track existing on said lens blank. Then, the lens blank assembled with the film structure has a final optically useful area which is increased. |
