- 15 - ABSTRACT OF THE DISCLOSURE A method and apparatus for cleaning an optical surface such as an eyeglass lens involves the use of a cleaning head having a contact seal for engaging around the perimeter of the surface to be cleaned. The cleaning head defines a shallow cleaning cavity which includes the optical surface and the surface is cleaned by generating in the cavity a high velocity air flow across the surface, introducing a cleaning fluid into the air flow so as to scrub the surface, and terminating the introduction of cleaning fluid while maintaining the air flow to remove any residual cleaning fluid. A particular application of the method to simultaneously clean all four surfaces of the eyeglass lenses of a pair of 3-D glasses is also disclosed.
