Eyestrain (tired eye muscles) isn't the only cause of poor vision. It could be dry eye. A study by researchers at Buskerud University College in Norway recently found that people blink 10 fewer times a minute while staring at a computer screen than they do while having a conversation. This causes your "tear film" - the outer layer of moisture on your eyeball - to evaporate more quickly.
"When your tear film isn't healthy, your visual acuity won't be as sharp and clear," says Dr Patricia Sabb, an associate professor of ophthalmology at the University of Wisconsin. So take a break and close your eyes. (I'm not napping, boss, just restoring my tear film.) If you still need more moisture, try Visine Tired Eyes.
