Abstract

A method for optimizing the performance in centration, rotation and stability of contact lenses makes use of the upper and lower eyelid geometries to maximize the lens-lid interaction for two different contact lens positions on the eye. The contact lenses are non-round lenses for maximum interaction with the eyelids.
