Patent ID: 7286287

Claim:
Vision aid in the form of telescopic spectacles with two lens systems, which each comprise: at least one objective lens and one eyepiece having an internal beam path therebetween, an autofocussing means which changes the focal length in order to adjust the lens systems according to a distance of the telescopic spectacles from an object, a means for changing a magnification factor of the lens systems, and at least one optical element that is distinct from said at least one objective lens and said eyepiece and that is positioned and arranged to match parallaxes 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, such that in each said lens system, said at least one optical element is movable along a curved guide so as to follow a curved path that crosses said internal beam path for changing an angle between external beam paths which run out of the respective lens systems towards the object, said curved guide being arranged so that as the distance of the telescopic spectacles from an object decreases there is a decrease in distance between respective optical elements of the lens systems.
