An optical preform has a predetermined spherical curve on a concave surface of the optical preform, a predetermined spherical curve on a convex surface of the optical preform and a near add power. A thin resin is applied to the concave surface of the optical preform and molded to form a toric layer by a mold having a toric, convex mold surface. The resin layer is then cured and the mold removed to form a finished ophthalmic lens.
