Título Colour vision of workers under non-actinic lighting

Resumen Results of surveys carried out in 104 practically healthy women (age 21-53) employed in a photographic paper factory. Working experience under non-actinic lighting ranged from 20 to 35 years (the control group comprised 50 women aged 20-35 years). The workrooms had no natural light. The lighting was in the red range of the visible spectrum (maximum energy at wavelengths of 635±2, 630±2 and 625±2nm); illumination was 4.6Lx and equivalent luminance was 0.65cd/m2. Detailed examination revealed a significant increase of colour distinction thresholds for each of the three basic colours (red, green, blue) in comparison with the control group. In most cases the maximum reduction in sensitivity was seen in the red receptors. The observed changes in colour vision resulted from the action of non-actinic lighting on the cortical part of the visual analyser. Measures aimed at improving the colour discriminating function of the eye and reducing visual fatigue in dark-room workers are proposed.
