ABSTRACT:
An improved contact lens carrying case has a pair of contact lens storage compartments integrally formed on a base member and includes a pair of respective storage compartment caps. Each storage compartment includes a lens retrieval structure, which is a free floating pop-up lens retrieval structure. The lens retrieval structure moves from an immersed position when the storage compartment cap is closed to a raised contact lens retrieval position when the storage compartment cap is opened. The lens retrieval structure has a convex upper surface and an outer upstanding flange. The upstanding flange is contacted by a plurality of fingers formed in the bottom of the cap to immerse the lens retrieval structure when the cap is closed. The lens retrieval structure is retained in the storage compartment by mating flanges on the inside of the upper open end of the storage compartment and on the outside of the lens retrieval structure.
