What can be done to minimize visual discomfort?
A. Visual discomfort can be minimized and, in some cases eliminated, by following some basic guidelines. First, everyone should ensure that their eyes are properly corrected. VDT users should set up their workstations to reduce glare and reflections from windows or overhead lights. They should adjust the brightness control or contrast knob (on some displays) to a comfortable setting and use a task light, if needed, for working with printed material. Also, adjust the furniture and VDT position for a comfortable viewing distance and angle plus easy access to the keyboard and other devices (e.g., a mouse). As with any visually intensive task, display users should focus on a distant object periodically and blink frequently.
