Abstract
A contact lens case comprising a container and a receptacle adapted to receive the container. The container includes a container body and a cover with the cover being releasably attachable to the container body. The cover has a surface tension area within the interior of the container. The surface tension area is adapted to have the contact lens adhered thereto by surface tension when the container has been drained of storage fluid and when the lens is made to contact the surface tension area by squeezing the container. When the container is then opened by raising the cover, the contact lens adheres to the surface tension area and is automatically removed from the interior of the container.
