Abstract:
A contact lens that is of generally uniform cross-section to allow proper transmission of oxygen-to the eye contains an inner optic region and an outer radial zone. Parallel grooves are placed in the outer radial zone on the anterior surface of the lens to cause the lens to align when the eye is blinked. The grooves can form a fine grating and can be placed in a superior or inferior region of the outer radial zone, or they can be placed in a ring or other configuration in this region.
