Paper Abstract

The literature presents many examples of visual distress (Gunnarsson and Soderberg, 1983) and (Ostberg, 1975) which indicate that many VDT operators suffer from ocular discomfort. Task design, room lighting, VDT screen glare, improper refraction correction, and the physical workstation environment are often given as the reasons for observed visual distress without delving into the specific mechanisms or combinations thereof of visually induced fatigue. There has been little noticeable improvement made up to today even though many more VDTs are in use.
