The present invention relates to a quality control method for optometric measurements including the following steps: (a) recording, via computer, a first record (14) that includes at least one first value of a first identifier (12), enabling identification of a glasses wearer (1), and at least one other value of another identifier (13) enabling identification of an optometric apparatus (15) on a first optometric measuring site (10); (b) carrying out at least one optometric measurement (16) of the wearer; (c) sending, to a second site (20), a digital measurement data set (18) including the optometric measurement result (16) from step (b), the digital data set (18) being linked, via computer, to the first record (14); and (d) digitally processing the optometric measurement result (16) from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers (12) of the glasses wearer and the optometric apparatus (13) of the first record (14).
