摘要:
The invention relates to a method for determining the visual acuity of a user. Two spaced outer markings (3, 4) and an orientation marking (5) lying between the two outer markings but not on a straight connecting line (6) of the outer markings (3, 4) are displayed to the user on a display (1) of an electronic device (2) or in a virtual three-dimensional representation in the context of a respective individual test as part of a plurality of individual tests carried out one after the other as a series of tests, and the user is required to move the orientation marking (5) on the display (1) perpendicularly to the straight connecting line (6) of the outer markings (3, 4) by actuating the electronic device (2) until the user perceives the orientation marking (5) as lying on the straight connecting line (6). After the orientation marking (5) has been manipulated, the electronic device (2) then registers the effective distance (7) between the orientation marking (5) and the straight connecting line (6). At least two or three individual tests are carried out in which the outer markings (3, 4) are arranged along the same main axis (8-11), and at least the vertical main axis (8) and the horizontal main axis (9) are measured as part of a series of tests. After the manipulation process, the registered effective distance (7) from the individual tests of the series of tests is used as a measurement for ascertaining the visual acuity.
