Abstract: The invention provides a method producing contact lenses, including the step of: holding the molded silicone hydrogel contact lens attached to the one of the female mold half or the male mold half with a vacuum supplied with a suction cup; deforming a surface of the one of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached to with a pin so as to separate the molded silicone hydrogel contact lens from the mold half attached to and to transfer the molded silicone hydrogel contact lens to the suction cup; moving the suction cup away from the pin while the suction cup continues to hold the molded silicone hydrogel contact lens remains; applying a compressed gas to blow the molded silicone hydrogel contact lens away from the suction cup into a container.
