The invention relates to a system for testing the eyesight and detecting and correcting visual defects, comprising a human subject (10) with two eyes (12; 16), at least one image display device (40; 50) which is designed to display three-dimensional images and on which at least one test chart (41; 51) containing at least two optotype zones (411, 412; 511, 512) can be displayed, and at least one computer (60) for controlling the at least one image display device (40; 50). In order to create a system with improved detection, evaluation and correction of visual defects, according to the invention, the system includes at least one first image display device (40) for the far range and at least one second image display device (50) for the close range, the distances (47; 57) of said image display devices from the eyes (12; 16) of the subject (10) being different, the computer (60) allows, by means of software that can be run thereon, optotypes of different types, sizes, colors, contrasts and/or brightness to be generated on the test charts (41; 51) and different three-dimensional backgrounds to be generated on the image display devices (40; 50), and at least one corrective device (30), on which different lenses and/or prisms (322, 323, 324; 342, 343, 344) and/or 3D separating filters (321; 341) can be activated, is placed in front of the eyes (12; 16) of the subject (10).
