Abstract: The present invention relates to a pair of spectacles for stereoscopic pictures based upon the principle of the Pulfrich effect. The direction in which a moving object is moving in a picture or the moving direction of a video camera is marked on the spectacles for stereoscopic pictures to obtain a correct stereoscopic image, so that the viewer can easily and readily determine which of a darker lens or a lighter lens is applied to which eye.
