Abstract
The present includes a progressively variable focal power ophthalmic lens that has a unique geometry which significantly reduces aberrations in the lens. The aberrations are reduced by altering the traditional geometry associated with peripheral areas of the lens from a spherical shape to an aspherical shape. Still another advantage of the lens geometry of the present invention is that the aberrations remain low after the lens is rotated to accommodate the left or right eye.
