After polymerization and/or cross-linking of a lens forming material (P) within a mold cavity () of a mold () comprising female and male mold halves () to form an ophthalmic lens non-polymerized and/or non-cross-linked lens forming material is flushed away from the mold halves () with a jet of a fluid flushing medium, such as, e.g., water or a solvent or an inert gas. Subsequently the molded lens is dried. In accordance with the invention the flushing is accomplished with the mold halves () still in the closed position.
