Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

Method for storing information on a spectacles lens, spectacles lens blank or spectacles lens semi-finished product

A holding device () holds a lens () at its lens edge () with the aid of an adhesive connection (). The adhesive connection () is applied only at one adhesive point or only at two spaced apart adhesive points (). Each holding device () provided with a lens () is positioned on the dip frame in such a manner that the lens () is positioned above its holding device (). A method is provided for finishing lenses () wherein the lenses () are subjected to various sequential finishing steps of a finishing process and the lenses () 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 ().

Transport arrangement for manipulating lenses

Holding assembly for a lens

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