A mold assembly for forming an ophthalmic lens article includes a first mold and a second mold. The first and second molds are assembled together to define a mold cavity therebetween having a profile corresponding to that of the ophthalmic lens article to be formed. The mold cavity is filled with a polymeric material which is polymerized to form the ophthalmic lens article. At least one of the first and second molds is a resin mold which is formed from a resin material, and a portion of at least a molding surface of the resin mold is directly irradiated with UV radiation so as to provide a UV-treated surface. The ophthalmic lens article formed in the mold cavity is held on the resin mold such that the ophthalmic lens article adheres to the UV-treated surface upon separating the first and second molds away from one another.
