Contact lens blister packages and related methods are described. The present devices include a thermoplastic base member with a grip portion, a distal end region, a first side region extending from the proximal end region to the distal end region, a second side region opposing the first side region, and a cavity configured to contain a packaging solution and a contact lens. The cavity comprises has a bottom wall with a bottom wall perimeter and a sidewall extending upwardly from the bottom wall perimeter to an upper cavity edge defining a cavity perimeter. A plane formed at the intersection of the bottom wall perimeter with the sidewall slopes away from the substantially linear portion of the cavity perimeter.

Contact lens blister packages

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.

Method and apparatus relating to manufacture of molds for forming contact lenses

Method and apparatus for manufacturing a contact lens comprising: dispensing a plurality of separate portions () of a liquid composition onto a contact lens mold section (), each separate portion of the liquid composition having a volume of less than about 1000 nano-liters.

Contact lens curing systems and methods are described. A contact lens curing system includes an oven that has a plurality of curing zones, a mold advancement system for moving contact lens mold assemblies between the plurality of zones, and a controlled atmosphere in the curing zones that provides a substantially chemically inert environment in which contact lens precursor materials can be polymerized in contact mold assemblies located in the curing zones. Methods of producing contact lenses include curing contact lens precursor materials in contact lens mold assemblies in the lens curing system.

Thermal curing methods and systems for forming contact lenses

Contact lens curing systems and methods are described. A contact lens curing system includes an oven that has a plurality of curing zones, a mold advancement system for moving the contact lens mold assemblies between the plurality of zones, and a controlled atmosphere within the curing zones that provides a substantially chemically inert environment in which contact lens precursor materials can be polymerized in contact lens mold assemblies located in the curing zones. Methods of producing contact lenses include curing contact lens precursor materials in contact lens mold assemblies in the lens curing system. As an example, an oven for curing contact precursor materials in molds, the curing process being done in an inert atmosphere, includes a plurality of heating zones, such as three heating zonesor two heating zonesand a mold advancement system for moving the molds between the plurality of zones, wherein a first zone and second zone of the plurality of zones are maintained at different temperaturesor
