Plastic ophthalmic lenses are coated with a scratch-resistant coating using a spin coating process. The lenses are separated from lens mold pieces, and the lenses are routed through a coating system where the lens coating is applied. A conveyor moves the lens mold pieces toward an inspection station while the corresponding lenses are moving through the coating system. The operation of the lens coating system and the conveyor are coordinated so that the coated lens and the lens mold pieces from which that lens was made are delivered as a group to the inspection station.

Method of applying scratch-resistant coatings to plastic ophthalmic

A new resilient compressible printing element having a rubber layer with foamed closed cells therein. The closed cells are formed by the use of blowing agents which are activated and foam the material while an external pressure is applied to the material to restrict expansion.
