Zusammenfassung:	Embodiments of the technology relate to a contact lens having a core that is covalently coated by a hydrogel layer, and to methods of making such a lens. In one aspect, embodiments provide for a coated contact lens comprising a lens core comprising an outer surface; and a hydrogel layer covalently attached to at least a portion of the outer surface, the hydrogel layer adapted to contact an ophthalmic surface, wherein the hydrogel layer comprises a hydrophilic polymer population having a first PEG species and a second PEG species, the first PEG species being at least partially cross-linked to the second PEG species.
