ABSTRACT:
An ophthalmic lens is disclosed for changing the focal point of a light-transmitting element. Formed from a light-transmitting silicone, the lens has a concave surface for creating suction when applied to a smooth surface. An exposed surface opposes the concave surface for providing a specific diopter. The lens quickly and impermanently attaches with finger pressure to a desirable smooth surface such as the lens of eyeglasses.
