Abstract (en)
[origin: WO2020178167A1] The present invention relates to a data record, stored on a storage medium, for use in a method for producing a spectacle lens, a method and a computer program for generating the data record, and a method for producing a spectacle lens. The data record comprises at least the following data values: spatial coordinates of a reference point on each eye (112, 112') of the wearer; at least one spatial direction vector for specifying at least one viewing direction (120, 120') of the wearer through the spectacle lens; and a spatial frame rim curve or rim curve (128, 128'). Using the present methods, the spectacle lens can already be produced following a single capture of a data record for adapting the spectacle lenses to the wearer of the pair of spectacles and to the spectacle frame (150) selected by the wearer. As a result, a spectacle lens different to the spectacle lens originally selected by the wearer can subsequently be used for the pair of spectacles without a further data record having to be established for the wearer for this adaptation.
