A device for cleaning soft contact lenses includes a cage having two cavities to loosely receive soft contact lenses therein. The cavities are defined by spaced ribs and provide surfaces approximating the surfaces of the lenses to be contained therein. The cage is positionable within a container which is fluid tight and can be associated with a rotary drive. The drive is oriented to rotate the container in a horizontal axis. The container includes an appropriate fill line allowing filling of one-half of the internal volume of the container with multipurpose liquid or cleaning solution. The rims of the lenses contained within the cage are arranged with the planes of such lenses substantially parallel to the axis of rotation and displaced from that axis to accommodate lifting the lenses repeatedly out of the body of liquid and then fully immersing them. A method for cleaning contact lenses includes loosely containing the lens so that it may move about the cage, repeatedly moving the lens fully into and out of a body of liquid through rotation in a substantially horizontal axis. The lenses are rotated slowly at three to ten revolutions per minute.

[ What is claimed is:] [10.]10. A device for cleaning contact lenses, comprisinga cage including two cavities sized to receive a soft contact lens each with clearance about the soft contact lens and including interstices for fluid flow through the cavities, the cavities each having a convex surface and a concave surface in mating orientation and displaced apart from one another;a fluid tight container receiving the cage and including a jar and a liquid tight lid, the jar having a fill line at one-half the volume of the interior of the container with the jar mated with the liquid tight lid, the jar having a first socket and the lid having a second socket opposed to the first socket with the jar mated with the liquid tight lid, one of the first and second sockets being asymmetrical about an axis extending through the first and second sockets and the other of the first and second sockets being symmetrical about the axis extending through the first and second sockets, the cage further including first and second tabs each positionable within the first and second sockets, each tab being rotatable within the symmetrical socket and non-rotatable within the asymmetrical socket;a rotary drive operatively coupled to the fluid tight container with the axis of the rotary drive being substantially horizontal, the cage in the fluid tight container being oriented with the substantially horizontal axis of the rotary drive being substantially parallel to the plane of the rim of a soft contact lens within the cage and displaced from the plane on the concave side of the lens, the two cavities being laterally adjacent and extending along the substantially horizontal axis of the rotary drive.
