Abstract: L'invention se rapporte à un procédé de détermination d'une lentille ophtalmique pour un il d'un porteur, le procédé comportant les étapes de : - mesure, sur le porteur en vision binoculaire, des coordonnées tridimensionnelles du centre de rotation de l'il du porteur; - mesure (10) d'au moins une direction de regard en posture naturelle - détermination de la position souhaitée de la lentille ophtalmique; - calcul des caractéristiques de la lentille ophtalmique en utilisant les coordonnées mesurées et la position déterminée et la direction mesurée en posture naturelle. La mesure de la position du centre de rotation de l'il en vision binoculaire assure que la lentille obtenue est mieux adaptée au porteur.
