ABSTRACT:
Disclosed is an optically corrected shield for unitary lens eyeglasses or safety helmets. The shield is characterized by an optical centerline and a mechanical centerline, which intersect each other at an angle. The lens is oriented on the head of the wearer by a frame or helmet that maintains the lens in a position such that the optical centerline is maintained substantially in parallel to the normal sight line of the wearer. Lenses are thus provided which have improved optics when mounted in an as-worn orientation such that they exhibit both vertical "rake" and horizontal "wrap." Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.
