ABSTRACT:
A method for modifying the shape of a spheric or toric non-corrective lens blank such that astigmatic and peripheral defects are reduced. The outer convex and inner concave sides of the lens are initially designed according to the Gullstrand Formula. Thereafter, a visual axis of the lens is defined relative to a reference axis of the lens blank. In the preferred toric lens, the visual axis of the lens is offset from the reference axis. Once the visual axis is defined, the inner concave surface of the lens is modified so as to improve optical quality in a visual center surrounding the visual axis.
