How often do you rest or exercise your eyes? For me, not as often as I would like to. I stare at a computer screen for 8 to 9 hours while at work, go home and stare at the TV screen for 3 hours, and on the weekends I'm doing both. It's sad, but such the life of a technology editor and avid Internet user.

According to the American Optometric Association, approximately 75 percent of computer users complain of visual discomfort after prolonged computer use. If this sounds like you, then your eyes are probably working overtime. Instead of waiting to go blind, just take 10 minutes a day with the Eyeport.

The Eyeport is an electronic vision training system that claims to improve your visual performance. "Through a combination of sound, color and light, the Eyeport optimizes the ability of the eyes to aim, track, focus and work together as a team," according to the company's site. Invented by Dr. Jacob Liberman and cleared by the FDA, the Eyeport certainly looks strange, but it's supposed to be easy to use. (Just don't poke your eye out.)

Each unit comes with a special pair of glasses with filters. Put on the glasses, look into the unit, and alternating red and blue lights will flash. However, the eye behind the red filter will see only the red light, while the eye behind the blue filter will only see the blue light. Because the lights turn on in different directions, patterns, and speeds, your eyes will experience various types of motion, including horizontal, vertical, diagonal, near, and far.

The science behind the alternating red and blue lights is called chromatic aberration. "The focusing system contracts when it sees red and relaxes looking at blue. By combining eye exercises with specific colored lights, the Eyeport strengthens your vision skills in a revolutionary new way," says the company.

The Eyeport comes with preprogrammed workouts and multiple speed settings to exercise and train each eye individually. It's used by surgeons, police, professional athletes, pilots, and other professions. Not convinced? In 2007, a pilot study conducted at Northeastern State University College of Optometry demonstrated that "use of the EYEPORT significantly improved visual attention, focus and depth perception in subjects previously diagnosed with Attention Deficit Hyperactivity Disorder (ADHD)."

The Eyeport retails for $199.95 and can be purchased online at www.exerciseyoureyes.com.
