Abstract A contact lens storage unit which is formed of first and second mating members. On one of these members, which may be the cap of the lens storage unit, a dome-like contact lens supporting element is provided. A cover, having a concave surface which cooperates with the dome-like contact lens supporting element to encage a contact lens is also provided. Finally, the unit includes a raised annular ring disposed about the dome-like contact lens supporting element. Complementing threads provided on both members and a seal complete the lens storage unit.
