Abstract: 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.

Abstract: The invention relates to a method for photographically observing and/or documenting the fundus of an eye, comprising: producing a lighting beam path by means of a lighting module for lighting at least one partial area of the fundus by using an at least approximately punctiform or at least areally limited lighting source, producing an image plane in the lighting beam path for the creation of photographic recordings, separating the pupil cross-sectional area into a detectable observation region and an undetectable lighting region, producing an image area that contains the image of the fundus on the image plane, dividing the image area in strips in the lighting beam path into a lighted region and unlighted regions, and imaging the third and fourth Purkinje reflection on the image area, wherein at least one Purkinje reflection, the third and/or fourth Purkinje reflection, is located in the unlighted regions of the image area.
