1. Adjust your Workstation
Screen fatigue or computer vision syndrome can be a result of poor posture. Adjust your chair and desk area so your feet rest comfortably on the floor. Your screen should be 50 to 60cm away from your eyes and 10-15 degrees below them. This will help the position of your head and neck.
2. Take frequent breaks.
Make sure you take 10 min breaks every hour to prevent pain on your neck, back and shoulders. Breaks should be taken throughout your working day. Try to stand up, walk around for a bit and stretch your arms, legs, neck and shoulders to release tension and muscle fatigue.
3. Exercise your eyes.
Another cause of screen fatigue is focusing fatigue. Avoid focusing on the screen constantly. One exercise you can do is to look away from your screen every 20 min, gaze at a distant object for 20 secs (20 feet away). This is called the 20-20-20 rule. Looking far away relaxes the focusing muscle inside the eye and reduces fatigue. A second exercise is to look far away at an object for 10-15 seconds, then gaze at something up close for 10-15 seconds. Then look back at the distant object. Do this 10 times.
4. Minimize glare.
Glare from light reflecting off walls, surfaces and reflections on your computer screen also can cause computer eye strain and screen fatigue. Installing an anti-glare screen protector on your computer or laptop can reduce glare. If you wear glasses, consider lenses with anti-glare or anti-reflective (AR) coating. AR coating reduces glare caused on both surfaces of the eyeglass lenses.
5. Blink more often.
Blinking moistens the eyes and helps in avoiding dryness of the eyes and irritation. When looking at a screen, we tend to blink less frequently. Tears coating the eye evaporate faster and that causes dryness in long periods of non-blinking. Also, the air in many environments is dry, which can increase how quickly your tears evaporate, placing you at greater risk for dry eye problems. To reduce your risk of dry eyes during computer use, try this exercise: Every 20 minutes, blink 10 times by closing your eyes as if falling asleep (very slowly). This will help re-wet your eyes.
