Abstract: Disclosed is a method for altering the visual performance of a subject using an optical system arranged in front of at least one eye of the subject, and including: b) determining an optotype; c) displaying the optotype to the subject in such a way that it is visible by the subject through the optical system; d) assessing the visual performance of the subject viewing the optotype through the optical system; and e) adding a positive or negative altering value of spherical optical power to the optical system. The method includes, before step b): a) choosing a target value of visual performance; and in that, at step b), the optotype has a size which is determined depending on the target value of visual performance; at step e), the altering value of spherical optical power is determined depending on the target value of visual performance.
