Title Visual accommodation changes in VDU-operators related to environmental lighting and screen quality
Bibliographic information Oct. 1984, Vol.27, No.10, p.1071-1082. Bibl.
Abstract Study on the possible relations between operator's accommodation changes after 6h work at a display unit and workstation lighting and screen characteristics. For 29 operators, the visual accommodation before and after work, workplace lighting, luminance, contrast and screen qualities were measured during day and night shifts. The state of visual accommodation was determined by laser optometry. The relation between lighting conditions and accommodation changes was low but significant. The influence of screen characteristics was more evident during the night shift.
