A unitary lens and haptic construction integrally formed by selective erosion from the same sheet of starting material, comprising a relatively thick rigid central lens component having a generally circular periphery, and relatively thin pliant generally annular outer haptic component extending radially outward of and distributed circumferentially about the lens periphery. Erosion may be effected by chemical etching, plasma-ion discharge or photo-etching. <IMAGE> |
