The frame consists of a top holding bow (2) and a bottom holding bow (3), of which the one (3) is arranged in front of the panorama screen (1) and the other (2) is arranged behind the panorama screen (1). In the centre of the spectacles the bottom holding bow (3, 5) is drawn up to the top holding bow (2,9) in the shape of an inverted V and carries the clamping device. The clamping device is formed by a pressure roller (8) which is arranged on the bow (3, 5) and elastically engages over and behind the panorama screen (1). <IMAGE>
