本发明涉及一种用于检验视觉功能并识别和矫正视觉缺陷的系统，包括具有双眼（12；16）的测试者（10）、至少一个设置用于显示三维图像、可在其上显示至少一个具有至少两个验光字体范围（411、412；511、512）的测试表（41；51）的图像显示设备（40；50）和至少一个用于控制至少一个图像显示设备（40；50）的计算机（60）。为了提供具有改进的识别、评估和矫正视觉缺陷的系统，根据本发明提出，该系统具有至少一个用于远距离区域的第一图像显示设备（40）和至少一个用于近距离区域的第二图像显示设备（50），这些设备与测试者（10）的眼睛（12；16）相距的距离（47；57）不同，不同类型、大小、颜色、对比度和/或亮度的验光字体可以通过计算机（60）借助可在其上运行的软件在测试表（41；51）上生成，且不同的三维背景可在图像显示设备（40；50）上生成，并且至少一个矫正设备（30）布置在测试者（10）的眼睛（12；16）前方，在该矫正设备上可激活不同的透镜和/或棱镜（322、323、324；342、343、344）和/或3D分离滤光器（321；341）。

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).
