FIELD: cosmetic industry.
SUBSTANCE: invention relates to cosmetic contact lenses. Disclosed is a method of producing a cosmetic silicone hydrogel contact lens, involving: (i) applying a transparent coating on a lens-forming surface of a first lens mold; (ii) applying a paint composition to the transparent coating; (iii) optionally repeating step (i), step (ii) or both step (i) and step (ii); (iv) feeding lens material into a first lens-forming mold; (v) using a second lens-forming mold; and (vi) curing the lens material to form a cosmetic silicone hydrogel contact lens; wherein the transparent coating does not contain a dye; and contains a non-reactive hydrophilic polymer; and binder polymer.
EFFECT: obtaining cosmetic silicone hydrogel contact lenses with reduced blurring and increased durability.
