Title:
コンタクトレンズを形成するための熱硬化方法および熱硬化システム
Document Type and Number:
Japanese Patent JP5396656
Kind Code:
B2
Abstract:
Thermal curing methods and systems for forming contact lenses includes an oven (10) that has a plurality of heating zones (40,50,60), a mold advancement system (230) for moving the contact lens mold assemblies between the plurality of zones, and a controlled atmosphere within the heating zones that provides a substantially chemically inert environment in which contact lens precursor materials can be polymerized in contact lens mold assemblies (160) located in the heating zones. Methods of producing contact lenses include curing contact lens precursor materials in contact lens mold assemblies in the lens curing system.
