Abstract
A cleaning system configured to use a hydrogen peroxide solution to clean contact lenses. The cleaning system includes a reservoir to hold the cleaning solution and a complex base coupled to the reservoir to insure a hermetically closed reservoir environment. The complex base is separated into at least a first and a second segment. A lens holder assembly holds the lenses within the solution and is coupled to the complex base in the first segment. A motor is located in the second segment of the complex base to selectively introduce a catalyst to the cleaning solution. The cleaning system has additional features that permit the system to allow for the storage of the contact lenses by converting a neutralized cleaning solution into a storage solution to prevent recontamination.
