[Evaluation of refractive values in patients working for several years at video display terminals. A long-term study].

The authors discuss whether working at a VDT (video display terminal) over a period of years causes non-reversible changes in refraction, especially if it induces a drift towards myopia. A total of 107 persons who had been working at VDT for many years were examined at 2-year intervals and the observations compared with those recorded in 69 persons who had never worked at a VDT. Changes in the correction strengths of their spectacles were evaluated.
