Abstract
Binocular telescopic magnifying spectacles, both telescopes of which are pivotally mounted on a common plane, wherein each imaginary pivoting axis (8) of the telescopes 91) lies outside the telescopes (1) and on the side opposite the telescopes (1) of the ocular exit pupil (9) at a distance (d) from the ocular exit pupil (9), which is smaller than the diameter of the eye (D). The adjustment device for convergence and the adjustment device for the distance are mechanically coupled.
