1. A dynamic contact lens comprising:
a peripheral portion;
one or more fenestrations disposed in the peripheral portion;
an interior dynamic portion coupled to the peripheral portion, wherein the interior dynamic portion, when worn on an eye, is configured to form with the eye a cylindrically shaped tear lens, the interior dynamic portion assuming
a conforming configuration configured to provide a first optical power to an eye; and
at least one non-conforming configuration configured to provide a second optical power to the eye, wherein the second optical power is different than the first optical power;
wherein the lens comprises a material having a Young's modulus from about 0.1 MPa to about 3 MPa; and
wherein the lens is configured to correct an astigmatism when worn on the eye.
