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. According to the invention, the connecting portions between the front frame and the temples of the spectacles are formed as a pair of hinges which protrude from the inside front frame and are spaced apart from each other so that a space therebetween receives the hinges of a pair of standard glasses worn by a viewer to support the stereoscopic spectacles on the standard glasses with great stability. This also enables the stereoscopic spectacles to be reduced in size so that they may be worn more stably by those who do not wear vision correcting glasses.
