-Modify your workstation. Adjust your workstation and chair to the correct height.
Use proper lighting.

-Match the computer screen to the brightness of the environment. The contrast between the background and on-screen characters should be high.

-Minimise the glare. Use window shades, blinds or drapes to block excessive sunlight or install an anti-glare screen to minimise reflections.

-Take frequent breaks. Full-time computer users should take a 10 minute break every hour.

-Blink more often. Tears in the eye evaporate more rapidly during long non-blinking phases and cause dry eyes.

-Get an eye examination done.

-Re-focus your eyes. Look away from your computer screen every 10-15 minutes and focus for 5-10 seconds on a distant object.

-Exercise even when sitting. Move about or exercise frequently.

-Get sufficient sleep. Fatigue promotes eyestrain.
