Patent

CA 2761782

The invention relates to ophthalmic spectacles for characterizing a convergence of the eyes (100, 200) of a wearer. Each lens (1, 2) of the spectacles is provided with output sections for guiding a radiation towards the side areas (ZD1, ZG1, ZD2, ZG2) of an eye of the carrier, in which the right and left portions of the corneal margin (L) of said eye are in motion. The lens further comprises input sections for collecting the portions of said radiation reflected in said side areas of the eye. A computing unit is also combined with the spectacles in order to determine the convergence of the eyes of the wearer from detection signals measuring the portions of the radiation that are simultaneously collected by the input sections of the two lenses.

Une paire de lunettes ophtalmiques est adaptée pour caractériser une convergence des yeux (100, 200) d'un porteur. Chaque verre (1, 2) de la paire de lunettes est muni de sections de sortie pour diriger un rayonnement vers des zones latérales (ZD1, ZG1, ZD2, ZG2) d'un il du porteur, où se déplacent des portions droite et gauche d'un limbe (L) dudit il. Ledit verre est muni en outre de sections d'entrée pour collecter des parties dudit rayonnement réfléchies dans lesdites zones latérales de l'il. Une unité de calcul est aussi associée à la paire de lunettes, pour déterminer la convergence des yeux du porteur à partir de signaux de détection mesurant les parties de rayonnement qui sont collectées simultanément par les sections d'entrée des deux verres.
