[Load factors at visual display terminals (author's transl)].
A medical examination and questionnaire in various office workplaces (N = 295) shows that in intensive work at visual display terminals rheumatic and asthenopic disorders are very frequent. Muscle pain and eye complaints are correlated. The incidence of eye disorders and visual acuity are related to lighting conditions (local and temporal oscillation of characters on the visual display) at the individual workplaces.

[Oscillating light from characters on screens].
An apparatus for measuring the sharpness, the oscillation degree and the stability of characters of 8 different VDTs were developed. Furthermore the contrast of luminances between the essential surfaces was measured. The following results were observed: 2 VDTs had good ergonomic qualities, one was only sufficient and 5 VDTs had insufficient ergonomic light conditions.
