Abstract: A method for determining the visual acuity, wherein two spaced outer markings and an orientation marking lying between but not on a straight connecting line are displayed to the user on a display in an individual test as part of a plurality of tests. The user is to move the orientation marking on the display perpendicularly to the straight connecting line by actuating the device until the user perceives the marking as lying on the straight connecting line. Afterwards, the electronic device registers the effective distance between the orientation marking and the connecting line. At least two tests are carried out in which the outer markings are arranged along the same main axis, and at least the vertical main axis and the horizontal main axis are measured. After the manipulation, the effective distance from the individual tests of the series is used for ascertaining the visual acuity.
