    Abstract: PROBLEM TO BE SOLVED: To provide a method for determining the shape of a contact lens which is capable of correcting the aberrations of a high degree measured with the patient's eye by limiting the occurrence of the undesirable aberrations when the lens is worn to the eye and is adapted to meet individual characteristics. SOLUTION: This method includes a step of measuring the optical aberrations of the eye to be corrected, a step of determining the shape of the back of the lens from the determined anatomical area of the cornea in order to obtain a prescribed mechanical behavior of the lens when the system is placed above the eye, a step of measuring the optical aberrations of the eye to be corrected and a step of determining the shape of the front of the lens from the measured optical aberrations of the eye combined with the data relating to the shape determined with respect to the back of the lens in order to correct the aberrations. This system has a measuring unit for measuring the anatomical area and aberrations of the eye and an electronic computation unit.

    Abstract: L'invention concerne un procédé de conception optique d'une paire de lentilles ophtalmiques pour la correction des défauts de réfraction sphérique et cylindrique des yeux d'un porteur, comportant une étape de définition (10) des besoins de correction sphérique et cylindrique du porteur pour différentes proximités de vision, et une étape de détermination (20) des puissances sphériques et cylindriques des lentilles ophtalmiques en des points de vision de différentes proximités, en fonction des besoins de correction du porteur. Selon l'invention, la détermination (20) des puissances d'au moins une des deux lentilles ophtalmiques est réalisée de manière à limiter l'écart obtenu entre elles sur l'addition de puissance sphérique équivalente entre les points de vision de différentes proximités, et/ou la variation du vecteur de puissance cylindrique entre les points de vision de différentes proximités. L'invention concerne également une paire de lentilles ophtalmiques conçue suivant un tel procédé.
