Abstract
A system of contact lenses includes at least two contact lenses, each lens having a visual correction for a non-rotationally symmetric eye aberration. Each lens has a different level or degree of a stabilization that is characterized by a thickness differential between a thickness of a stabilization zone and a thickness of a non-stabilization zone.
