Eye discomfort when reading microfilm in different enlargers.

At a large banking firm, the lighting conditions under which middle-aged women employees read microfilms in different enlargers were studied. Complaints from the staff were analyzed and compared with the results obtained. Discomfort glare, due to heavy contrasts between the dark documents on the screens and other light surfaces in the visual fields, was the main cause of the complaints. It was recommended that individual near-work spectacles might decrease or eliminate some of the disturbing factors which had led to the subjective complaints. Suggestions were made for improving the enlargers.

Discomfort glare and disturbances from light reflections in an office landscape with CRT display terminals.

In the present investigation, the lighting was studied in an office landscape equipped with 17 CRT display terminals. Complaints from the personnel were analysed and compared with the results obtained. Discomfort glare and reflections on the screen were found to be the main causes of the complaints. Discomfort glare resulted from the difference in luminance between the dark screen and other light surfaces in the room. Reflections from windows and ceiling lighting developed on the glossy screen and were often found to have higher luminance values than the text on the screen. On the basis of the present results, guiding principles are suggested for the design of lighting in similar working places.
