The invention provides a contact lens manufacturing method comprising a process for removing unprocessed molded silicone hydrogel contact lenses from mold halves in a relatively efficient and consistent manner. The method of the invention involves using a silicone fluid (or so-called silicone oil) as non-reactive diluent in SiHy lens formulation for making SiHy contact lenses. Resultant SiHy contact lenses cast-molded from such a SiHy lens formulation can have a significantly reduced adhesion force with the molding surfaces of a lens mold and consequently a higher efficiency and consistency in removing unprocessed molded SiHy contact lenses from mold halves can be achieved. This method of the invention can be easily implemented in a production environment for enhancing the production yield.
