ABSTRACT:
A contact lens case (101) comprises a base (103) having a left cavity (105A) and a right cavity (105B) for storing contact lenses (113A,113B). An upward-facing base dome (109A,109B) in each cavity supports the lenses with the rims of the lenses downward. A lid (106) comprises downward-facing lid domes (121A,121B) to retain the lenses on the upward-facing domes of the base. The lid domes allow expelling of air during closing of the case to maintain good hydration of the lenses.
