The method comprises the steps of: providing a first mold half and second mold half each having opposing top surfaces at least one of which has been hollowed out to define a cavity for forming said ophthalmic device and at least said first mold half further defining a boundary for a release element, said boundary is part of said cavity, said release element comprising a ramped surface, said cavity having a corresponding ramped surface, and said release element having its widest part near the top surface of said at least said first mold half that defines said release element therein. The mold of this invention has a hollowed-out portion as part of the cavity to provide a release element to the molded ophthalmic device.
