The invention relates to a device for determining eye torsion, comprising a camera and an image processing unit, which is designed to carry out a method for determining eye torsion. In the method, at least two images of an eye are recorded and image data are produced from said images, and at least one characteristic feature of the eye is identified from the image data, for example a blood vessel. Direction histograms of the feature in both images are produced and compared with each other. The angle of the torsion of the eye is determined from the shift of the directions in the direction histograms.
