Abstract

The device has a laser mounted on a headband fixed on a front of a subject and a screen, where the screen has a size of a paper sheet and is held by the subject. The screen is equipped with a graduated scale whose graduation is in degree and is function of distance between the screen and the eye. The graduation permits to visualize the projection of the laser when the subject is in horizontal looking position as well as when the subject is in reading position.

Description

2885292 12885292 1

L'invention concerne un dispositif de mesure de l'angle d'inclinaison de la tête et l'angle de rotation de l' oeil lors de la lecture.  The invention relates to a device for measuring the angle of inclination of the head and the angle of rotation of the eye during reading.

Il n'existe pas actuellement de système simple de calcul de l'angle d'inclinaison de la tête pour choisir le verre progressif approprié.  There is currently no simple system for calculating the angle of inclination of the head to choose the appropriate progressive lens.

l'invention permet de remédier à ces inconvénients. En effet, selon une forme préférentielle, elle consiste en un serre tête muni d'un laser projetant une ligne soit horizontale soit verticale par simple rotation du laser. Le serre tête permet d'incliner le laser afin que sa projection arrive sur un écran de la taille d'une feuille. Cet écran est tenu par le sujet. L'écran est muni d'une échelle graduée verticalement, la graduation est en degré, elle est fonction de la distance entre le laser et l'oeil du sujet, elle permet de visualiser la projection du laser quand le sujet est dans la position de regard horizontal ainsi que lorsque le sujet est dans la position de lecture. La différence entre les deux projections donnent l'angle de rotation de la tête.  the invention overcomes these disadvantages. Indeed, according to a preferred form, it consists of a head clamp provided with a laser projecting a line either horizontal or vertical by simple rotation of the laser. The headband tilts the laser so that its projection arrives on a screen the size of a sheet. This screen is held by the subject. The screen is equipped with a scale graduated vertically, the graduation is in degree, it is a function of the distance between the laser and the eye of the subject, it allows to visualize the projection of the laser when the subject is in the position of horizontal view and when the subject is in the playback position. The difference between the two projections gives the angle of rotation of the head.

Par différence entre l'angle de rotation de la tête et l'angle de lecture on obtient l'angle de rotation vertical de l' oeil.  By difference between the angle of rotation of the head and the reading angle, the vertical angle of rotation of the eye is obtained.

De même si le laser projette une ligne verticale et que la graduation est horizon-tale, cette graduation permet de visualiser la projection du laser quand le sujet est dans la position de lecture. La différence entre les deux projections extrêmes donne l'angle de mobilité horizontale de la tête et par différence avec l'angle de lecture horizontal, l'angle de rotation horizontal de l'oeil.  Similarly, if the laser projects a vertical line and the graduation is horizontal, this graduation makes it possible to visualize the projection of the laser when the subject is in the reading position. The difference between the two extreme projections gives the angle of horizontal mobility of the head and by difference with the horizontal reading angle, the horizontal rotation angle of the eye.

Selon une variante, le laser peut projeter une croix  According to a variant, the laser can project a cross

2 REVENDICATIONS2 CLAIMS 1)Dispositif de mesure de l'angle d'inclinaison de la tête et de l'angle de rotation de l'oeil lors de la lecture, destiné notamment à la mesure morphologique du mouveinént de la tête et de l'oeil pour le choix de verres ophtalmologiques progressifs, caractérisé en ce qu'il est composé d'un laser monté sur un serre tête fixé sur le front d'un sujet et d'un écran. Cet écran est de la taille d'une feuille dé- papier, il est tenu par le sujet. L'écran est muni d'une échelle graduée, la graduation est en degré, elle est fonction de la distance entre l'écran et l'oeil du sujet; elle permet de visualiser la projection du laser quand le sujet est dans la position de regard horizontal ainsi que lorsque le sujet est dans la position de lecture.  1) Device for measuring the angle of inclination of the head and the angle of rotation of the eye during reading, intended in particular for the morphological measurement of the movement of the head and the eye for the choice progressive ophthalmological lenses, characterized in that it is composed of a laser mounted on a headband attached to the forehead of a subject and a screen. This screen is the size of a paper sheet, it is held by the subject. The screen is equipped with a graduated scale, the graduation is in degree, it is a function of the distance between the screen and the eye of the subject; it allows you to view the laser projection when the subject is in the horizontal viewing position and when the subject is in the playback position. 2) Dispositif suivant la revendication 1 caractérisé en ce que le laser projette une ligne horizontale et que la graduation de l'échelle de l'écran est verticale. La graduation permet de visualiser la projection du laser quand le sujet est dans la position de regard horizontal ainsi que lorsque le sujet est dans la position de lecture. La différence entre les deux projections donne l'angle de rotation de la tête et par différence avec l'angle lecture, on obtient l'angle de rotation vertical de l'oeil 3) Dispositif suivant la revendication 1 caractérisé en ce que le laser projette une ligne verticale et que la graduation de l'échelle de l'écran est horizontale. Cette graduation permet de visualiser la projection du laser quand le sujet est dans la position de regard horizontale ainsi que lorsque le sujet est dans la position de lecture. La différence entre les deux projections extrêmes donne l'angle de mobilité horizontale de là' tête et par différence avec la lecture horizontale, on obtient l'angle de rotation de l'oeil.  2) Device according to claim 1 characterized in that the laser projects a horizontal line and that the graduation of the scale of the screen is vertical. The graduation shows the laser projection when the subject is in the horizontal viewing position and when the subject is in the playback position. The difference between the two projections gives the angle of rotation of the head and, by difference with the reading angle, the vertical angle of rotation of the eye 3) Device according to Claim 1, characterized in that the laser projects a vertical line and that the scaling of the scale of the screen is horizontal. This graduation makes it possible to view the projection of the laser when the subject is in the horizontal viewing position as well as when the subject is in the reading position. The difference between the two extreme projections gives the angle of horizontal mobility of the head and in difference with the horizontal reading, we obtain the angle of rotation of the eye. 4) Dispositif suivant l'une des revendications précédentes caractérisés en ce que le laser projette une croix.  4) Device according to one of the preceding claims characterized in that the laser projects a cross.
