2. Eye Strain

Eyes can become strained after staring at a computer screen for a long time, particularly if working in bad light, in glare or with a flickering screen.

Fortunately, eyestrain is usually a temporary problem.

Symptoms include:

• Burning or itching eyes
• Blurring or double vision
• Headache
• Nausea
• Fatigue

Solutions:

• Use monitors which don't flicker
• Have blinds at the windows so that the sun doesn't shine directly on the screen
• Use suitable lights that disperse light evenly and don't shine on the screen
• Use a screen filter
• Keep your eyes at least 18 inches from the screen
• Regularly look away from the screen and focus on something in the distance
• Take regularly breaks - at least 5 minutes break every hour
• Have regular eye tests and wear glasses if prescribed
