1. A method of treating an eye of a patient, the eye comprising a cornea, an epithelium and a sclera, the method comprising:
providing a covering comprising:
an inner portion having an inner rigidity and at least one inner radius of curvature; and
an outer portion having an outer rigidity and at least one outer radius of curvature;
wherein the inner rigidity is greater than the outer rigidity; and
applying the covering against the eye so that the covering flexes with the inner portion at least partially disposed over and substantially conforming to the cornea and with the outer portion engaging the eye along the epithelium, the sclera, or a combination thereof; wherein,
the engagement holds the inner portion on the optical portion of the cornea;
the inner rigidity is from 2.5E-6 Pa-m3 to 6.41E-3 Pa-m3; and
the outer rigidity is no more than 4E-5 Pa-m3;
wherein the inner portion of the covering is formed from a material selected from silicone, silicone hydrogel, and a combination thereof.
