1. A fenestrated contact lens comprising:

  • a lens body adapted for placement adjacent a surface of an eye, said lens body having an inner surface and an outer surface;

    said lens body having a first plurality of fenestrations extending therethrough, wherein each of said first plurality of fenestrations is tapered to have a cross-section which is larger at the inner surface of the lens body and smaller at the outer surface of the lens body, so as to direct a flow of lachrymal fluid outward from a first location between the surface of said eye and the inner surface of said contact lens to a second location adjacent the outer surface of the contact lens; and

    said lens body also having a second plurality of fenestrations extending therethrough, wherein each of said second plurality of fenestrations is tapered to have a cross-section which is larger at the outer surface of the lens body and smaller at the inner surface of the lens body, so as to direct a flow of lachrymal fluid inward from a third location adjacent the outer surface of the contact lens to a fourth location between the surface of the eye and the inner surface of said contact lens.
