A method of removing an ophthalmic lens from a lens mold portion is provided and includes reciprocally displacing a region of the mold portion and thereby causing an edge portion of the ophthalmic lenses to become detached from the mold portion. Related apparatus, methods of manufacturing ophthalmic lenses, delensing stations, and manufacturing times are provided.

Methods and apparatus for manufacture of ophthalmic lenses

Apparatus and methods are described for manufacturing contact lenses by forming a contact lens mold half, and removing the mold half. The mold half can then be combined with a complementary mold half and used to cast-mold a contact lens. The apparatus includes first and second plates each carrying tool halves. The plates reciprocate between an open, spaced apart configuration, and a closed configuration in which they hold complementary tool halves in contact with one another. When the plates are opened after forming a mold half, a gripper plate removes the mold half from the first plate or the second plate.

Method and apparatus for manufacturing contact lenses

Methods and apparatus for exchanging tools and/or tool assemblies used to form different types of molds for in injection-molding machines, are described. The exchange of tools and/or tool assemblies is made using a robot. Contact lens mold halves and assemblies for molding contact lenses of different powers or types can be made with a single injection-molding apparatus.
