||Visual fatigue in video display terminal operators: Objective measure and relation to environmental conditions
||1988, Vol.60, No.2, p.81-87. Illus. 31 ref.
||Female (28) and male (16) CRT data-acquisition operators in Italy were subjected to ophthalmological examinations. A questionnaire was administered to determine prevailing subjective ocular symptoms and discomfort. Workplace illumination, luminance and constrast between text and screen background were determined. In 10 (26.3%) subjects significant myopisation was observed. A significant correlation between reported eye discomfort, ocular asthenopia and myopisation existed. Illumination level, luminance and contrast were found to be of great importance for visual symptoms: neither asthenopia nor myopisation occurred at adequate lighting and contrast conditions.
