Abstract
Methods and devices for an oxygen permeable liquid crystal contact lens are disclosed herein. An oxygen permeable liquid crystal contact lens may include a coating. The coating may be made of one or more layers of an oxygen non-permeable material. The coating may be modified to allow oxygen to permeate though the liquid crystal contact lens to a mammalian eye.
