    摘要: In a method for providing optotypes for determining distance visual acuity, a test subject position is provided for a test subject and a display surface at a display position. An individual test distance between the test subject position and the display position is, for example, detected automatically. An individual target variable is determined for optotypes which are matched to the detected individual test distance according to a predetermined role. Digital optotype image data are provided which contain optotypes scaled to the individual target variable. The digital optotype image data are displayed on the display surface.
