摘要：
The invention relates to a device and a method for checking human vision, comprising an image-generating module for generating any test images, an imaging module, used to image the test image provided by the image-generating module on the retina of the eye as a stimulus, the imaging module containing at least one optical component having variable focal length, such that the test image of the image-generating module is perceptible to the eye from virtually simulated and variable distances, an accommodation measuring apparatus, a viewing direction measuring apparatus, and a control and evaluation module, which records and/or further processes the information. The accommodation of the eye can be stimulated by means of the particular test image, and the viewing direction of the eye can be measured simultaneously or in alternation, and fed to a control and evaluation module. Both eyes can be checked simultaneously by generating virtual binocular images.
