VISION MYTHS: SITTING IN FRONT OF A COMPUTER SCREEN FOR HOURS ON END CAN DAMAGE YOUR EYES AND IF YOU LOOK CROSS-EYED LONG ENOUGH, YOUR EYES WILL STAY THAT WAY
Sitting in front of a computer screen for hours on end can damage your eyes.
Well, it sure doesn't do them any good, but fortunately the eyestrain and fatigue caused by overuse of computers and video display terminals (VDTs) is only temporary. Eyestrain and fatigue can be unwelcome byproducts of any close-up task that requires prolonged use of the eye muscles. What can you do to relieve the strain? Take frequent breaks. Rest your eye muscles by periodically looking up or across the room. Keep the monitor twenty-four inches away. You may find it helpful to use a pair of "computer glasses," so that your eyes don't have to work so hard. (See your eye doctor.)
If you look cross-eyed long enough, your eyes will stay that way.
They won't.
