Title An ophthalmologist's evaluation of work at visual display units
Original title Die Beurteilung der Arbeit an Datensichtgeräten aus augenärztlicher Sicht [in German]
Bibliographic information Sep. 1978, Vol.28, No.9, p.256-258.
Abstract Work at CRT display terminals may cause organic and functional eye disorders, and the damage may occur without the operator being aware of the fact. This article contains recommendations to be followed when visual display unit (VDU) operators' eyesight is to be tested: workpost inspection, job description, roundup of technical data concerning the workpost, working conditions, complete eye examination. When inspecting the workpost the ophthalmologist should be accompanied by a member of the staff delegates' council. The author stresses the importance of eliminating reflected light by correct placing of the VDU, shielding the VDU from ambient light, or placing a screen behind the operator. Other factors to be taken into consideration include inclination of the CRT screen in relation to the natural angle of vision, ambient lighting and legibility. The characters of the text displayed on the screen should be clearly legible, not too small and pale or soft yellow in colour.
