Summary: | The invention provides a method for producing ophthalmic lenses, preferably contact lenses, more preferably silicone hydrogel contact lenses. This method involves applying a coat of catanionic vesicles onto the molding surfaces of a mold. By having a coat of catanionic vesicles on the molding surfaces of a mold, mold separation force and lens defects generated during mold opening and de-molding process can be substantially reduced. |
