Abstract

Disclosed is an optically corrected lens for nonprescription, dual lens eyeglasses. In a preferred embodiment, the anterior surface of the lens lies on a portion of a first sphere having a first center. The posterior surface of the lens lies on the surface of a second sphere having a second center. The first and second centers are offset from one another to provide a tapered lens. The lens is oriented on the head of the wearer by a frame that maintains the lens in a position such that a line drawn through the first and second centers is maintained substantially in parallel to the normal sight line of the wearer. Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.
