Abstract
The invention provides dual stabilization zones that interact with an individual's eyelids so that at least the upper eyelid strikes both stabilization zones of a lens at the same time. The stabilized lenses of the invention maintain their on-eye orientation better as compared to conventionally stabilized lenses.
