Abstract
Disclosed is a method for evaluating the vision of an individual under certain brightness conditions, using a screen displaying an image including a background and characters to be deciphered which appear on the background. The method includes the following steps: a step of regulating the brightness of the background of the image; and a step of regulating the brightness of the characters to be deciphered which appear on the image, the two steps being independent from each other so as to obtain the desired contrast between the background and the characters.
