Abstract
An apparatus for finishing toric surfaces of ophthalmic lenses. The apparatus includes a frame and a first assembly for providing an orbital, break-up motion to a lapping tool having a polishing surface of a selected base curve and cross curve. A second assembly is also mounted upon the frame for providing an orbital, break-up motion to a lens to be finished. Adjustment means are provided for selectively adjusting the amplitude of the orbital, break-up motion of both the lapping tool and the lens.
