Abstract
Ophthalmic lenses for correcting astigmatism having a posterior surface with a central optic zone, a peripheral zone, and a blending zone therebetween. The surface of the central zone may be asphero-toric and the surface of the peripheral zone aspheric, with these flatter slopes smoothening out the transition between the central and peripheral zones. The blending zone gradually transitions the curvatures of the central and peripheral zones to further smoothen out the central-to-peripheral-zone transition.
