People with bifocal glasses feel comfortable when reading if they can look down at a desk top to read. However, reading a vertical display screen with bifocal glasses produces discomfort in that it requires tipping the head back. A system for reading a display screen which eliminates this problem is constructed and operates as follows. A mirror is positioned parallel to the desk top to reflect the electronically produced mirror image on a display panel to the eye, the image corresponding to papers on the desk. If the rays from the panel center to the mirror are perpendicular to the panel surface, there will be no apparent foreshortening effect. If the mirror is further positioned slightly above the desk top, there will be room for an associated keyboard positioned at least partially under the mirror.
