Place the monitor directly in front of you and sit about an arm’s length away from it. To minimize glare and reduce eye fatigue, position the monitor so that sunlight, desk lamps, and overhead lights do not shine directly on the screen.
When you are sitting in front of the monitor, the top of the screen should be slightly below eye level so you look down, rather than up, at the screen. If your monitor is too low, you can raise it by placing it (or the computer) on a stand. If the monitor has a tilt and swivel base, you can use it to adjust the position of the screen for comfortable viewing.
To produce an image that is clear and easy to look at, adjust the monitor’s brightness and contrast controls. If your screen flickers, you can minimize it by selecting a dark background using either the brightness and contrast controls or your software.
To prevent eyestrain, rest your eyes occasionally by closing them or focusing on a fixed spot in the distance.
