Many people suffer from computer related eye strain. The good news is that there are some easy steps you can take to minimise the problem.
Have an eye health check
See an optometrist to make sure your eyes are healthy.
Wear appropriate spectacles
Computer screens are farther away than a comfortable reading distance. You may need dedicated computer glasses to see the screen clearly.
Turn off your screen and look for reflections coming off the surface. Try to move your screen or bright light sources behind you to minimise reflections.
Update your screen
LCD screens flicker less and reflect less light.
Use a larger screen
Chose a display that is at least 19 inches.
Lower your screen
Keep the top of the screen at or below eye level. Looking downward is more relaxing and makes it easer to see through the lower part of bifocal lenses.
Keep screen clean
Dust and fingerprints reduce contrast and can be a source of glare and reflections.
Adjust screen brightness
Try to adjust the brightness so that it is about the same as the surrounding surfaces. As a test try looking at a very white web page. If it looks bright and glary reduce the brightness.
Increase text size
Screen text size should be three times the smallest text size you can read from your normal viewing position. Adjust text size in your computer’s display control panel.
Adjust your work station
Place any written material on a stand close to the screen and make sure the hard copy is well lit.
Computer users blink less frequently. This leads to drying of the surface of the eye. You cannot learn to blink more frequently but you can pause every 15 minutes and close your eyes for a few seconds.
Take a break
Use the “20-20-20” rule. Every twenty minutes gaze at an object twenty feet away for twenty seconds.
