Abstract

A holding device (1) holds a lens (6) at its lens edge (5) with the aid of an adhesive connection (16, 17). The adhesive connection (16, 17) is applied only at one adhesive point or only at two spaced apart adhesive points (16, 17). A transport arrangement handles lenses (6) during hard coating in a dip trough. The transport arrangement includes a dip frame with receptacles for holding devices for lenses (6). Each holding device (1) provided with a lens (6) is positioned on the dip frame in such a manner that the lens (6) is positioned above its holding device (1). A method is provided for finishing lenses (6) wherein the lenses (6) are subjected to various sequential finishing steps of a finishing process and the lenses (6) are cemented to the same holding device during finishing. The application of adhesive is only at one adhesive point or at two spaced apart adhesive points (16, 17). A turning arrangement for turning a holding device (1) holding a lens (6) at its lens edge (5) includes a turning tooth system associated with the holding device (1) and a translatorily movable turning element that coacts with the turning tooth system.
