Abstract
Methods for making ophthalmic lenses are generally discussed herein with particular discussions extended to plastic injection molded ophthalmic lens molds that are machined or lens buttons located on the injection molds that are machined. The machine process can include setting a lens axis of the ophthalmic lens and machining a ballast that is aligned to a major axis of a toric zone.
