1. Method for optotype representation ( 2 ) via an image output device ( 4 ) for a visual acuity test and/or determination of a refraction, characterized in that optotypes ( 10 ) are displayed in a three-dimensional image ( 6 ) constructed from two fields ( 5 , 7 ) offset against each other by one parallax, so that an image separation occurs in such a way that the optotypes ( 10 ) are monocularly discernible in binocular conditions, wherein the three-dimensional image ( 6 ) is binocularly discernible and the three-dimensional image is discernible in the background.
