Abstract
Abstract A contact lens disinfection unit constituted by a container, a cap detachably mounted on the container, and a lens and catalyst block holder mounted on and depending from the cap and extending into the container when the cap is mounted on the container. The holder engages a pair of contact lens for holding the contact lenses with the surfaces thereof exposed to the space around the holder, and has structure for holding catalyst block on the holder in a position for circulation of a disinfectant solution, from the space around the holder over the catalyst block. The catalyst block can be detachably held so that it can be replaced when the catalyst is depleted.
