Visual fatigue measured after VDT- and printed-work.

Effects of polyphenol on visual fatigue caused by VDT work.

Visual fatigue of VDT (visual display terminal) operators poses a serious problem for corporations where VDT work is a major part of operations. In this study, an investigation in a corporation was carried out to examine the effect of polyphenol on recovery from visual fatigue of the visual function caused by working at a VDT. Three kinds of parameters were used for evaluating the effect of pol...

Luminance of the surround and visual fatigue of VDT operators.

Luminance distribution in the visual field is considered as one of causal factors with a significant influence on visual fatigue, especially for intensive and extended Video Display Terminal (VDT) work. The aim of the study was to define visual fatigue of VDT operators for different values of surrounding luminance. Experiments were carried out in laboratory conditions under 3 lighting condition...

Investigating the Visual Fatigue in VDT Operators in the Banks of Qasr-e Shirin (Kermanshah-Iran)

Background & Aims of the Study: Due to the increasing use of computers in the administrative and social structure of Iran, it seems that, in the near future, eye and body symptoms caused by computer work will become one of the most important health issues in our society, and threaten the health of the workforce and consequently, lead to significant financial and industrial losses. The aim of th...

Physiological indices of visual fatigue due to VDT operation: pupillary reflexes and accommodative responses.

In spite of the clarification of some significant physiological factors of visual fatigue caused by VDT work, pupillary reflexes have not been studied as to how they are affected after prolonged visual work. This study examined visual function changes objectively in terms of pupillary reflexes and lens accommodative responses after a 4-hr VDT operation task. The relationship between the two fun...
