Abstract: An edge of a lens blank an eyeglass lens having a shaped edge is measured at a plurality of peripherally offset measuring positions and respective control values are generated corresponding thereto and supplied to an applicator. This applicator applies a hardenable material in liquid form to the edge of the eyeglass lens and is controlled such that an amount and/or position of the material is applied at the measuring positions according to the respective control values in a controlled manner. The hardenable material is chemically or radiation-cured to form on the edge of the lens a functional layer that has an optical, magnetic, electric, or electronic function.

Abstract: The invention relates to a method for producing a spectacle lens, wherein an edge structure is produced on the spectacle lens. The invention is characterized in that expected light effects produced or at least influenced by the edge structure of the spectacle lens, in particular light reflections and/or light transmissions, are ascertained for the spectacle lens with the edge structure, and the ascertained light effects are reduced, in particular in terms of intensity and/or direction and/or color, by applying one or more layers onto the edge structure of the spectacle lens.

Abstract: The invention relates to a method for coating eyeglass lenses, in particular for coating the edge of eyeglass lenses by means of a needle metering device or jet metering device, wherein the eyeglass lens and the metering device are moved relative to one another and at the same time a coating material is applied to the eyeglass lens, in particular to the edge thereof, from the metering device. The control data for controlling the movement of the eyeglass lens and/or of the metering device are determined before and/or during the application process on the basis of geometric data of the metering device and geometry data of the eyeglass lens surface to be coated, said geometry data of the eyeglass lens surface to be coated being measured or being drawn from a data store.
