Abstract
Abstract Object of invention is such an appliance which is suitable for stereoscopic displaying of video images. It is wearable on head having a common stiff frame with two video image displays built in it; then an optical system, containing lenses and mirrors or prisms, is located, arranged symmetrically. Video image diplays (1), e.g. cathode ray tubes, while wearing on head, are located near the temples; in front of the screen (3) there is a mirror or a prism having reflecting surface, having of 45°-75° angles with the plain of the screen on two sides symetrically fitting into optical train between the screen (3) and the concerned pupil, then a lense or lense-system (8), then there is a reflecting mirror (7) having the area not greater than that of the average pupil, in front of the pupils (5), fixing of this mirror (7) is made of transparent material or is covered. The enumerated elements are built in the frame cover having many parts, from which part left and right side cover (9) contain video image display (1), mirrors or prisms (4) in front of the screen (3) and lenses or lense-systems (8), its connecting element (12) is transparent material and/or is constructed out of the virtual sight and rests on the ridge of the nose.
