Abstract
Contact lenses are purified by contact with ozone in a compact system that includes an ozone generator, a purifying liquid in a lens chamber, and a pumping system for flowing liquid and gas in a way that brings ozone dissolved in a purifying liquid into contact with the lenses. In some embodiments, undissolved ozone can also contact the lenses. Several preferred arrangements are shown for accomplishing the lens purification with such an ozone disinfection system.
