Abstract

A quality control method for optometric measurements includes 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 from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.

(b) carrying out, by means of the optometric apparatus of the first site, at least one optometric measurement comprising at least one measurement of an ocular refraction parameter of at least one eye of the spectacle wearer and/or a measurement of horizontal and vertical positions of the pupil of the eye of this wearer relative to a frame intended to accommodate the corrective lens;

(c) transmitting to a second site a numerical measurement dataset comprising the optometric measurement result of step (b), the numerical dataset being computationally associated with the first recording; and

(d) digitally processing the optometric measurement result computationally associated with the first recording depending on numerical reference data and/or the respective identifier of the optometric apparatus of the first recording;

(e) determining a numerical visual-correction prescription dataset of a new corrective lens depending on the numerical dataset computationally associated with the first recording;

(f) having the numerical visual-correction prescription dataset digitally signed and validated by a professional qualified to prescribe the refraction powers of a new corrective lens;

(g) transmitting to a third site the numerical prescription dataset associated with the first identifier of the wearer and with a signature attached to the qualified professional;

(h) certifying the signature transmitted in step (g) and transmitting the result of this certification to the third site;

(i) generating at the third site a digital corrective-lens order dataset triggering the manufacture of this eyeglass;

(j) selecting an optical design or a category of optical design or adapting the calculation of the design depending on the signature attached to the qualified professional;
