A method for making contact lenses, comprising the steps of: obtaining a fluid lens-forming composition and a mold, wherein the fluid lens-forming composition comprises at least one member selected from the group consisting of a hydrophilic vinylic monomer, a silicone containing vinylic monomer, a silicone-containing crosslinker, a silicone-containing prepolymer, a hydrophilic prepolymer free of silicone, and combinations thereof, wherein the mold has a first mold half with a first molding surface defining the anterior surface of a contact lens and a second mold half with a second molding surface defining the posterior surface of the ophthalmic lens, wherein said first and second mold halves are configured to receive each other such that a cavity is formed between said first and second molding surfaces; applying a coating of an aqueous catanionic solution containing a cationic surfactant and an anionic surfactant onto the first molding surface or the second molding surface of the mold (preferably onto the first and second molding surfaces of the mold), wherein the weight percentage ratio of the anionic surfactant over the cationic surfactant in the aqueous solution is from about 0.1 to about 10, wherein the anionic surfactant is a salt of a C 5 -C 18 alkyl sulfates, a salt of a C 5 -C 18 alkyl sulfonates, a salt of a C 5 -C 18 alkyl benzene sulfonates, a N-C 8 -C 20 acyl sarcosinate salt, or a combination thereof, wherein the cationic surfactant is a C 8 -C 18 alkyl-trimethylammonium salt, a silicone containing polyquat, or a combination thereof; drying the coating of the aqueous catanionic solution to form a coat of catanionic vesicles on the first and/or second molding surface, wherein the formation of the coat of the catanionic vesicles on the first and/or second molding surfaces is characterized by having a percentage of reduction in mold separation force of at least about 50% relative to a control mold without any coat of catanionic vesicles thereon and optionally by having at most about 5 star-tears per lens on average, when being used in cast molding of ophthalmic lenses from the fluid lens-forming composition; introducing the fluid lens-forming composition into the cavity formed by the first and second molding surfaces with the coat of the catanionic vesicles formed in step thereon; actinically irradiating the fluid lens-forming composition in the cavity to form the ophthalmic lens; and opening the mold and removing the formed ophthalmic lens from the mold. obtaining a fluid lens-forming composition and a mold, wherein the fluid lens-forming composition comprises at least one member selected from the group consisting of a hydrophilic vinylic monomer, a silicone containing vinylic monomer, a silicone-containing crosslinker, a silicone-containing prepolymer, a hydrophilic prepolymer free of silicone, and combinations thereof, wherein the mold has a first mold half with a first molding surface defining the anterior surface of a contact lens and a second mold half with a second molding surface defining the posterior surface of the ophthalmic lens, wherein said first and second mold halves are configured to receive each other such that a cavity is formed between said first and second molding surfaces; applying a coating of an aqueous catanionic solution containing a cationic surfactant and an anionic surfactant onto the first molding surface or the second molding surface of the mold (preferably onto the first and second molding surfaces of the mold), wherein the weight percentage ratio of the anionic surfactant over the cationic surfactant in the aqueous solution is from about 0.1 to about 10, wherein the anionic surfactant is a salt of a C 5 -C 18 alkyl sulfates, a salt of a C 5 -C 18 alkyl sulfonates, a salt of a C 5 -C 18 alkyl benzene sulfonates, a N-C 8 -C 20 acyl sarcosinate salt, or a combination thereof, wherein the cationic surfactant is a C 8 -C 18 alkyl-trimethylammonium salt, a silicone containing polyquat, or a combination thereof; drying the coating of the aqueous catanionic solution to form a coat of catanionic vesicles on the first and/or second molding surface, wherein the formation of the coat of the catanionic vesicles on the first and/or second molding surfaces is characterized by having a percentage of reduction in mold separation force of at least about 50% relative to a control mold without any coat of catanionic vesicles thereon and optionally by having at most about 5 star-tears per lens on average, when being used in cast molding of ophthalmic lenses from the fluid lens-forming composition; introducing the fluid lens-forming composition into the cavity formed by the first and second molding surfaces with the coat of the catanionic vesicles formed in step thereon; actinically irradiating the fluid lens-forming composition in the cavity to form the ophthalmic lens; and opening the mold and removing the formed ophthalmic lens from the mold.
