A method for producing coated silicone hydrogel contact lenses each having a crosslinked hydrophilic coating thereon, comprising the steps of: (a) obtaining a silicone hydrogel contact lens from a polymerizable composition comprising at least one silicone-containing vinylic monomer or macromer and from 30% to 60% by weight of N-vinylpyrrolidone relative to the total amount of polymerizable components; and (b) contacting the silicone hydrogel contact lens with an aqueous solution of a homo- or copolymer of acrylic acid or C 1 -C 3 alkylacrylic acid to form a base coating on the silicone hydrogel contact lens, wherein the base coating exhibits a water-break-up-time (WBUT) of 20 seconds or more after the silicone hydrogel contact lens has been autoclaved at 115°C to 125°C in a phosphate buffered saline having a pH from 6.5 to 7.5 for 30 minutes, characterized in that the homo- or copolymer of acrylic acid or C 1 -C 3 alkylacrylic acid is polyacrylic acid, polymethacrylic acid, polyethylacrylic acid, polypropylacrlic acid, poly(acrylic acid-co-methacrylic acid), poly[(meth)acrylic acid-co-ethylacrylic acid], poly[(meth)acrylic acid-co-propylacrylic acid], poly[(meth)acrylic acid-co-acrylamide], poly[(meth)acrylic acid-co-vinylpyrrolidone], poly[ethylacrylic acid-co-acrylamide], poly[ethylacrylic acid-co-vinylpyrrolidone], poly[propylacrylic acid-co-acrylamide], poly[propylacrylic acid-co-vinylpyrrolidone], hydrolyzed poly[(meth)acrylic acid-co-vinylacetate], hydrolyzed poly[ethylacrylic acid-co-vinylacetate], hydrolyzed poly[propylacrylic acid-co-vinylacetate], or combinations thereof; and (c) covalently attaching and crosslinking a water-soluble and thermally-crosslinkable hydrophilic polymeric material having azetidinium groups onto the base coating to form a non-silicone hydrogel coating on the silicone hydrogel contact lens.
