Abstract
A cleaning device for a soft type contact lens includes a housing having a cleaning chamber fed with a cleaning liquid, a lens receiving container within the cleaning chamber and a stirring device for generating a liquid flow within the cleaning chamber and for cleaning said contact lens with the liquid flow. In order to clean the contact lens, a high speed liquid flow is generated, so that four kinds of processes of cleaning, rinsing, sterilizing, and preserving are carried out automatically within only one cleaning chamber without moving the contact lens. Therefore the lenses are not stained with dirt when moving them by finger from one process or place to another.
