Title: METHOD OF DETERMINING AN OPHTHALMIC LENS
Abstract:
The invention relates to a method of determining an ophthalmic lens for a wearer's eye, the method comprising the following steps: measurement, on the wearer in binocular vision, of the three-dimensional coordinates of the centre of rotation (COR) of the wearer's eye; measurement (10) of at least one viewing direction in a natural posture; determination of the desired position of the ophthalmic lens; calculation of the characteristics of the ophthalmic lens using the measured coordinates and the determined position and the measured direction in the natural posture. Measuring the position of the centre of rotation of the eye in binocular vision ensures that the lens obtained is best adapted for the wearer.
