1. Apparatus for inverting a plurality of contact lenses from a convex side-up position to a concave side-up position comprising:

  • a) a tray having opposite bottom and top surfaces having a common width W2 and including a plurality of perforations formed entirely through said tray from said top surface to said bottom surface, said plurality of contact lenses being positioned on said top surface with each one of said lenses being positioned over at least one of said perforations;

    b) a source for directing an air stream of predetermined velocity against said bottom surface of said tray, said air stream passing through said perforations and impinging upon and inverting lenses in said convex side-up position to said concave side-up position; and

    c) a substantially planar surface for supporting said tray, said planar surface including a recessed slot having a length L1 which is at least as long as said width W2 of said tray, said source being positioned within said slot with said air stream being directed outwardly of said slot toward said planar surface, whereby said tray may be moved across said planar surface over said slot with said air stream traversing and impinging upon said tray bottom surface, passing through said perforations and inverting said lenses as they are passed over said slot.
