A method and a device for removing molded soft contact lenses, high-precision intraocular lenses and the like, from the individual molds in which they are produced. Provided is an infra-red radiation or heater device constituted of silicon carbide IR-emitters, and which employs an individual infra-red emitter for each individual mold, to impart a desired thermal gradient.

Silicon carbide IR-emitter heating device and method for demolding lenses

This invention provides a method of manufacturing a contact lens comprising the step of: dosing a contact lens mold comprising optical mold surfaces with an oxygen-sensitive reaction mixture, wherein said optical surfaces of said contact lens mold have between from 0.13&times;10 to 2.6&times;10 moles/cm O available to interfere with the reaction of said reaction mixture. This invention further provides a method of manufacturing a contact lens comprising the steps of: dosing a contact lens mold comprising optical mold surfaces with a reaction mixture, and sealing said reaction mixture and said optical mold surfaces away from a gaseous environment, wherein said optical surfaces of said contact lens mold were exposed to said gaseous environment comprising greater than 0.5 percent oxygen just prior to said sealing step.
