Abstract

A description is given of a device for determining or discriminating the central thickness of lenses or eyeglasses, which is characterised by a plurality of master or template discs (3-A, 3-A', 3-B, 3-B', 3-C, 3-C', 3-D, 3-D') of different thickness in each case and by a support element (1; 2, 1A-1D) for holding the discs, it being possible before a lens or an eyeglass is subjected to the edging process for its central thickness after the processing to be determined or discriminated uniquely and with good precision (visually). <IMAGE>
