20100245763 | Progressive Power Lens And Method Of Designing The Same - A progressive power lens that prevents degradation in optical characteristics invited by deviation of a pantoscopic angle from the standard value. The lens includes an outer refractive surface and an inner refractive surface, at least one of which is a progressive surface. Because the amount and direction of aberrations generated in distance and near portions are different, correction is given to either or both of the surface powers of the outer and inner surfaces of the lens such that the distance and near portions are differently corrected. | 09-30-2010 |
