Beschreibung
Zusammenfassung:	A stable tinted hydrogel ophthalmic device and a process for producing tinted ophthalmic devices comprising: (a) applying a first colorant composition comprising at least one non-crosslinked binding co-polymer, at least one pigment, dye or mixture thereof and at least one printing solvent to a surface of an ophthalmic device mold; (b) adding up to an amount required to prepare an ophtalmic device, and over the non-crosslinked binding co-polymer of step (b), an uncured hydrogel formulation, wherein said hydrogel formulation, when cured, has a oxygen permeability of greater than about 50 barrer; and (c) curing said hydrogel formulation to form a stable, tinted ophthalmic device.
