ABSTRACT:
There is described a method for forming lenses having substantially no optical power. The method includes forming, via in situ polymerization, a layer of non-uniform thickness of an optically clear, high scratch-resistant polymeric material on the convex surface of the lens. The lenses provided by the method are characterized by having maximum thickness in the central region of the lens and gradually diminishing thickness radially towards the periphery of the lens.
