[Binocular fusion of anamorphotic distorted images (author's trnasl)]

A astigmatic eye corrected with a spectacle lens results in an anamorphotic optical system which gives a distorted image of the environment on the retina. Fusion disturbances were ppresent especially in oblique astigmatism. The explanation for this can come either from a displacement of the image points on the retina or from the prismatic side effects of the spectacle lenses.
