Abstract
A contact lens assembly includes a proximal layer formed from a gas-permeable material, a distal layer with an optical element, an air cavity disposed between the proximal layer and the distal layer, wherein oxygen concentration across the air cavity is substantially uniform, and an gas transport region surrounding the air cavity for communicating gas between the air cavity and atmosphere. The contact lens assembly may further include a plurality of fins disposed within the air cavity where the plurality of fins has openings therethrough. One or both of the upper and lower surfaces of the air cavity may have an anti-reflection coating formed thereon.
