A system for testing eyesight and detecting and correcting visual defects of a human subject with two eyes (12; 16), with 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 with at least one computer adapted for controlling the at least one image display device (40; 50), wherein the system includes at least one first image display device for the far range and at least one second image display device for the close range whose distances (47; 57) differ relative to the eyes (12; 16) of the subject, wherein the distances (47, 57) of the image display devices (40, 50) and/or the positions thereof are adjustable relative to the eyes (12, 16) of the subject, wherein the computer is adapted for generating, by means of software that can be run thereon, optotypes of different types, sizes, colors, contrasts and/or brightness on the test charts (41; 51) and different three-dimensional backgrounds on the image display devices (40; 50), and wherein the system comprises at least one corrective device, which is disposed in front of the eyes (12; 16) of the subject, the corrective device having different lenses and/or prisms (322, 323, 324; 342, 343, 344) and/or 3D separating filters (321; 341) that can be activated, and wherein the computer is connected to at least one input device by means of which the subject or a system's operator sends, due to the return messages by the subject, signals to the computer by means of which the software controls the further generation of optotypes with regard to the types, sizes, colors, contrasts and/or brightness thereof and/or of background images or videos on the image display devices (40, 50) and/or the activation of lenses and/or prisms (322, 323, 324, 342, 343, 344) on the corrective device and/or the activation of 3D separating filters (321, 341) on the image display devices (40, 50), characterized in that the corrective device is configured as a fully automated corrective device having at least one actuator, wherein the at least one actuator is configured for activating or deactivating the 3D separating filters (321, 341) and/or lenses and/or prisms (322, 323, 324, 342, 343, 344), wherein the computer is adapted to control the actuator. wherein the system includes at least one first image display device for the far range and at least one second image display device for the close range whose distances (47; 57) differ relative to the eyes (12; 16) of the subject, wherein the distances (47, 57) of the image display devices (40, 50) and/or the positions thereof are adjustable relative to the eyes (12, 16) of the subject, wherein the computer is adapted for generating, by means of software that can be run thereon, optotypes of different types, sizes, colors, contrasts and/or brightness on the test charts (41; 51) and different three-dimensional backgrounds on the image display devices (40; 50), and wherein the system comprises at least one corrective device, which is disposed in front of the eyes (12; 16) of the subject, the corrective device having different lenses and/or prisms (322, 323, 324; 342, 343, 344) and/or 3D separating filters (321; 341) that can be activated, and wherein the computer is connected to at least one input device by means of which the subject or a system's operator sends, due to the return messages by the subject, signals to the computer by means of which the software controls the further generation of optotypes with regard to the types, sizes, colors, contrasts and/or brightness thereof and/or of background images or videos on the image display devices (40, 50) and/or the activation of lenses and/or prisms (322, 323, 324, 342, 343, 344) on the corrective device and/or the activation of 3D separating filters (321, 341) on the image display devices (40, 50), characterized in that the corrective device is configured as a fully automated corrective device having at least one actuator, wherein the at least one actuator is configured for activating or deactivating the 3D separating filters (321, 341) and/or lenses and/or prisms (322, 323, 324, 342, 343, 344), wherein the computer is adapted to control the actuator.
