Patent ID: 7455796

Claim:
A process for transferring a coating onto at least one geometrically defined surface of a lens blank which comprises: providing a lens blank having at least one geometrically defined surface; providing a flexible mold part having an internal surface bearing a coating and an external surface, the internal surface being conformable to the geometrically defined surface of the lens blank when brought into contact therewith; depositing on said geometrically defined surface of said lens blank or said coating a pre-measured amount of a curable glue; moving relatively to each other the lens blank and the flexible mold part to either bring the coating into contact with the curable glue or bring the curable glue into contact with the geometrically defined surface of the lens blank; applying a sufficient pressure onto the external surface of the flexible mold part so that the thickness of a final glue layer after curing is less than 100 micrometers; curing the glue; and withdrawing the flexible mold part to recover the lens blank with the coating adhered onto the geometrically defined surface thereof.
