Too much screen time, not enough blinking |

Blink more often. |
| When working at a computer, people blink less
frequently — about five times less than normal, according to studies. Tears coating the eye evaporate more rapidly during long non-blinking phases and this can cause dry eyes. Also, the air in many office environments is dry, which can increase how quickly your tears evaporate, placing you at greater risk for dry eye problems. Exercise your eyes. Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the "20-20-20 rule." Looking far away relaxes the focusing muscle inside the eye to reduce fatigue. |
| To ease eye strain, make sure you use good lighting
and sit at a proper distance from the computer screen. Another 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. This exercise reduces the risk of your eyes' focusing ability to "lock up" (a condition called accommodative spasm) after prolonged computer
work. |
