1. A non-transitory storage medium storing a data record for use in a method for producing a spectacle lens from a spectacle lens blank based on centration data, the data record comprising at least the following data values:
spatial coordinates of a reference point at each eye of a wearer;
at least one spatial direction vector for specifying at least one viewing direction of the wearer through the spectacle lens; and
a spatial rim curve or edge curve,
wherein the data record further contains additional information, and wherein the additional information relates to at least one correction of a data value,
wherein all centration values included by the centration data, which are used for producing the spectacle lens for a spectacle frame selected by a wearer of a pair of spectacles, have already been determined only from knowledge of the data values of the data record, or
wherein the data values of the data record are used directly to optimize a front surface and a back surface of the spectacle lens.
