ABSTRACT:
The difference in optical performance, such as astigmatism, the radius of curvature of a first surface, etc., of left and right lenses is kept at or below a specific level, and the difference in optical performance and the radius of curvature of the first surfaces between new and old lenses when the wearer changes lenses is also kept at or below a specific level, the result being lenses that are more comfortable to wear and are more attractive.
