A vision aid in the form of telescopic spectacles has two lens systems, which each comprise at least one objective lens (70) and one eyepiece (71). An autofocussing element which changes the focal length of the lens systems for sharp focussing thereof according to the distance of the telescopic spectacle from the object is assigned to the lens systems. Furthermore, an element for changing the magnification factor by changing the focal length of the lens systems ("zoom") and finally an element for matching the parallax between the lens systems of the vision aid to the focal length which has been set according to the distance of the telescopic spectacles from the object are assigned to the lens systems. The parallax is adapted using adjustable optical elements (11) which are located in the beam path of the lens systems, with which elements the angle (13) between the beam paths (14) running from the lens systems (1) to the object can be changed.
