Question: How frequently should I take vision [1] breaks during computer use?

Answer: Every 20 minutes, according to Dr. Elise Brisco in Computers and Your Vision: What You Need to Know [2].

Brisco, an optometrist practicing at the Hollywood Vision Center in Los Angeles, advises that "too many people stare into the monitor for hours on end. This can help foster computer vision [1] syndrome. You need to look away from the computer every 20 minutes so your eyes [1] can relax their focus."
