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. Accordingly, it is possible to effectively clean the contact lenses without damaging the contact lenses.
