Abstract: A lens case for a contact lens cleaning device comprises a receiving case including a pair of holding chambers for accommodates a pair of both contact lenses and a cover which is detachably coupled to said receiving chamber for opening/closing the holding chamber. The receiving case comprise a pair of first introductory conduits each of which include an entrance opening to a bottom of the receiving case and an exit opening to the holding chamber so as to confront to a center of one side surface of the contact lens which is accommodated in the holding chamber.

Abstract: A cleaning device for contact lens which includes a housing having a cleaning chamber which is provided with a container chamber, a container disposed in the container chamber and forming a lens receiving chamber which receives contact lenses therein and a stirring device for generating a rising liquid flow which rises toward to the container chamber and is disposed at a lower side of the container. The container has plural passage holes which communicate between an inside of the lens receiving chamber and outside of the lens receiving chamber. At least one of the passage holes opens diagonally and downwardly as regard to the lens receiving chamber so as to introduce the rising liquid flow into the lens receiving chamber. Since the rising liquid flow flows diagonally from below into the lens receiving chambers via the passage holes, the contact lenses are gently floated in the lens receiving chamber so as to separate from the wall surface of the lens receiving chamber.

Abstract: A cleaning device for contact lenses includes a housing having a cleaning chamber, a stirring device for generating a liquid flow within the cleaning chamber, a heating device for boiling a liquid in the cleaning chamber, a feeding device for feeding the liquid into the cleaning chamber, a discharging device, a feeding amount detecting device for detecting a feeding amount of the liquid which is fed into the cleaning chamber, an operation controlling device for giving a signal to the stirring device, the heating device, the feeding device and the discharging device in response to the feeding amount of the liquid detected by the feeding amount detecting device, respectively and for performing a cleaning process, plural rinsing processes and a boil process.
