Abstract [en]

Examined relationships between operators' accommodation changes after 6 hrs of work at a display unit and work-station lighting and screen characteristics. The measurements were carried out in 2 field studies. Operator's visual accommodation before and after work, workplace lighting, and luminance contrasts and screen qualities for 29 display screen operators (mean age 27 yrs) were measured during day and night shifts. Field laser optometry was used for determining the state of visual accommodation. Photometric and radiometric characteristics of the display screens were measured using a spectrometer-photometer. Findings reveal a low significant relationship between lighting conditions on the one side and incidence of accommodation changes on the other. More Ss showed overaccommodation when working at stations with higher luminance contrast. The influence of screen characteristics, such as screen illuminance, luminance, and irradiance, upon visual accommodation were evident during the night shift.
