Title Visual display units - are they safe?
Bibliographic information Aug. 1978, Vol.30, No.8, p.357-362. Illus. 8 ref.
Abstract This article, by the Principal Medical Officer of the Occupational Health Service, British Post Office Telecommunications, gives background information on the design and development of visual display units (VDUs), followed by considerations on: real and doubtful health problems (possibility of ionising or non-ionising radiation from defective equipment; visual fatigue; subjective symptoms such as headache, irritability, nausea, anxiety, depression, etc.); eye strain due to wearing spectacles of focal length unsuited to the distance from the screen; ergonomic aspects; current research (including a 5-year investigation commenced in 1977 by the British Post Office). Immediately following the article (on p.363) is a commentary by a VDU operator, which endorses the guidelines for VDU operators issued by the Printing Industries Committee of the Trades Union Congress, recommending as a minimum at least a 30min break after every period of 2h work at a VDU.
