A contact lens that reduces power distortion and lens contact with the corneal surface resulting from lens flexure. The contact lens (10) is designed to include a central optical portion, a scleral skirt (90), and a transition portion (34) therebetween, overlying the cornea, the posterior surface of which is conformed to the local geometry of the underlying portion of the cornea, including corneal tilt and distortion. In an alternative embodiment representing a less expensive lens, the transition portion is designed to conform to a statistically average cornea. The central optical portion may have a posterior surface which is customized, is toric or spherical, depending on whether a custom or inexpensive soft lens is being designed. |
