Abstract
A selection aid for selecting lenses for spectacles on the basis of a plurality of customer-specific criteria contains a first disc and a second disc. The first disc has a selection area with criteria to be selected and selection recommendations and is divided into selection regions of equal size. The second disc is rotatably connected to the first disc about an axis of rotation. The second disc partly conceals the selection area and visually frees an area region of the selection area that corresponds to one of the selection regions in terms of size and shape.
