Abstract (en)
[origin: WO2017089681A1] The invention relates to a method for evaluating the vision of an individual under certain brightness conditions, using a screen displaying an image (1) comprising a background (2) and characters (3) to be deciphered which appear on said background (2). The method according to the invention is mainly characterised in that it comprises the following steps: a step of regulating the brightness of the background (2) of the image (1); and a step of regulating the brightness of the characters (3) to be deciphered which appear on the image (1), said two steps being independent from each other so as to obtain the desired contrast between the background (2) and the characters (3).
