Abstract
The invention provides a method for determining a geometrical parameter of an eye of a subject, such as for determining the position of a center of rotation of the subject's eye, such as for the purpose of personalizing the optical design of corrective ophthalmic lenses, wherein at least two images of the eye are captured with an image capture device while the subject looks in two different gaze directions, and on each image, the pupil and/or the iris of the eye are identified so that a geometrical parameter may be determined for determining a position of a center of rotation of the eye without requiring use of a reference accessory.
