An eyesight testing apparatus includes an imaging device for virtual imaging a test object located within a focal length of the imaging device and imaged at different distances into eyes of a subject located in a focal point of the imaging device, an optical deflection device arranged in a beam path between the imaging device and the test object to deflect the beam path by 180°, wherein the deflection device is displaceable in the direction of the beam path and the test object is not, a monitor device that generates the test object and that comprises a single monitor, optical components lying in the beam path sized so that both eyes are able to take part in a test, and so a partial beam path is formed for each eye, and a blocking device arranged in the beam path, which comprises two LCD blocking elements for the partial beam paths.
