Abstract
An improved method for configuring progressive ophthalmic lenses is disclosed. The method includes computing a traditional merit function with two changes. First, the merit function computation is limited by calculating only a preferred distance from the meridian rather than until 0. Second, an additional term is added to the merit function that calculates the mean sphere at a point that is at a reduced range from the maximum unwanted cylinder, rather than the entire range.
