The invention provides sparkle additives useful in producing cosmetic lenses, and lenses produced using the sparkle additives that produce a sparkle-effect when the lens is viewed on-eye. The sparkle effect is produced while, at the same time, maintaining the natural appearance of the eye.

Cosmetic contact lenses having a sparkle effect

The invention provides a method for producing tinted contact lenses in which diffusion of monomer into the colorant is aided by heating of the molds. The invention provides a method, and lenses produced by that method, that reduces the residual, unbound polymer on the lens surface and lens surface roughness.

Methods for the production of tinted contact 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.
