Abstract
Contact lenses for use in eyes are provided and include a lens body and a plurality of microchannels defined in a posterior face of the lens body. The microchannels are structured to promote effective tear fluid exchange between an exposed surface of the eye and a surface of the eye covered by the lens body. Each of the microchannels preferably includes a substantially junctionless, convex surface along a major portion of a length of the microchannel.
