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).

The invention relates to a method for determining, in a natural posture, at least one geometric/physiognomic parameter associated with the mounting of an ophthalmic lens in a spectacle frame intended to be worn by a wearer. The method comprises the following steps consisting in: (a) capturing at least one substantially frontal image of the wearer's head; (b) determining a measured value of an angle of inclination (A) during the capture of the substantially frontal image, which depends on the inclination of the wearer's head about a main axis perpendicular to a sagittal plane of the wearer's head; (c) determining a reference value of said angle of inclination corresponding to a natural posture of the wearer's head (10); and (d) determining the required geometric/physiognomic parameter on the basis of the substantially frontal image captured and as a function of the difference between the measured value of the angle of inclination determined in step (b) and the reference value of the angle of inclination determined in step (c).

The invention relates to a method for centering an uncut single vision ophthalmic lens (1) having an initial contour (2) associated with a center point (CO) and provided for being cut according to a final contour (3) associated with a pupil point, comprising the following steps: superimposing the pupil point of the final contour on the center point of the uncut lens, and; relatively adjusting the final contour inside the initial contour of the uncut lens. The step for adjusting the final contour inside the initial contour involves an angular orientation relative to the initial contour with regard to the final contour around the center point according to an angular position of adjustment in order to prevent or reduce the amount by which the final contour exceeds the initial contour of the lens.

The invention relates to a method (20) for correcting an individual behaviour in order to prevent the apparition or to slow down the progression of a visual defect, said individual wearing frame (4). According to the invention said method comprises the following steps: - a step (24) of determining parameters that characterize the behavioural conditions of the individual using correcting means securely fastened to the frame of the frame (4) in the preceding various situations for a set time; - a step (26) of comparing said parameters with preset reference values; and - a step (28) of correcting the behaviour of the individual using detecting means (1) that are securely fastened to the said frame (4), and that trigger when the difference between a parameter and the corresponding reference value diverges beyond a preset threshold value.

The present invention relates to a method and an associated system for ordering a spectacle lens. More particularly, the invention concerns a method for ordering a spectacle lens by a wearer (1), said method involving steps of: - Selecting (S1) a spectacle frame by the wearer (1); - Capturing (S2) at least one picture showing at least partially a face of said wearer (1) wearing the selected spectacle frame, at a picture capturing side (10) so as a position of said spectacle frame in respect with the wearer face is extractable from said at least one picture; - Obtaining (S3.1) a three dimensional shape of the selected frame at said picture processing side (20), - Processing (S3) said at least one picture for obtaining the position of said spectacle frame in respect with the wearer face at said picture processing side (20), and - Ordering (S6) to a lens manufacturing side (40) spectacle lens complying with said frame shape, said extracted frame position, and wearer data, wherein said wearer data comprises at least a prescription for the wearer (1).

The invention relates to a method for determining at least one behavioural, postural or geometric-morphological characteristic of a person wearing spectacles. According to the invention, the method comprises the steps of: a) illuminating the wearer's head using an infrared light source (220, 230, 240), b) acquiring an image of the wearer's head using an infrared image sensor (210); c) in the image, locating reflections from the infrared light surface, reflected by the two lenses of the spectacles; and d) using a computation unit (250) to deduce the required characteristic as a function of the positions of the reflections in the image.

The invention relates to a referencing device (1, 100) intended to be fixed to an eyeglass frame in order to spatially reference said frame, said device (1, 100) having a transverse bar (2, 102), a central extension (5), two lateral markers (3) and a central marker (4), each marker (3, 4) consisting of a light area (12) and a darker area (11). The main characteristic of a clip according to the invention is that it comprises at least one mobile fastening member (7, 8) which is able to move along at least one slide (9, 10) of the bar (2, 102).
