In accordance with exemplary embodiments, the present invention provides scleral lenses comprising a central zone and at least one peripheral zone defined by an angle. In an exemplary embodiment, a peripheral zone is curved in either a concave or convex direction or is uncurved.

In accordance with exemplary embodiments, the present invention provides scleral lenses that do not demonstrate excessive pressure on the sclera and that allow for post lens tear exchange.
