Abstract
An apparatus and method for inverting a plurality of contact lenses between separate processing steps which treat the opposite concave and convex surfaces of the lenses. The lenses are initially placed convex side-up on a perforated lens support surface and are subjected to the first processing step which treats this surface of the lens. The support surface is then passed over an elongated air stream which traverses and is directed to impinge upon the bottom surface of the support whereby the air stream passes through the perforations in the support and inverts the lenses from the convex side-up position to a concave side-up position whereupon this surface of the lenses may be treated in a subsequent processing step.
