A contact lens is fitted to a cornea of a patient's eye to gradually alter the patient's cornea during continued wear to reshape the cornea to reduce the hyperopia and/or presbyopia condition. The contact lens has a plurality of zones that includes one or two optical zones, a plateau zone, a fitting zone, an alignment zone and a peripheral zone.
