Minimize glare.

Glare from light reflecting off walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain. Consider installing an anti-glare screen on your display and, if possible, paint bright white walls a darker color with a matte finish.

If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses.

Upgrade your display.

If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel LED (light-emitting diode) screen with an anti-reflective surface.

Old-fashioned CRT screens can cause a noticeable “flicker” of images, which is a major cause of computer eye strain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work.

Well lit computer environment

To ease eye strain, make sure you use good lighting and sit at a proper distance from the computer screen.

Complications due to flicker are even more likely if the refresh rate of the monitor is less than 75 hertz (Hz). If you must use a CRT at work, adjust the display settings to the highest possible refresh rate.

When choosing a new flat panel display, select a screen with the highest resolution possible. Resolution is related to the “dot pitch” of the display. Generally, displays with a lower dot pitch have sharper images. Choose a display with a dot pitch of .28 mm or smaller.

Also, choose a relatively large display. For a desktop computer, select a display that has a diagonal screen size of at least 19 inches.
