Vision-related symptoms occur in 50 to 90 percent of all workers who spend significant time working at a video display terminal, or VDT, according to the American Optometric Association, or AOA. The AOA has coined the term "computer vision syndrome," or CVS to describe various vision related problems associated with close computer work. Although some vision problems require correction by an eye care professional, simple exercises can relieve much eye strain associated with CVS.
Alter Your Focus
Many workers who use a computer take no more than two breaks of 15 minutes each during the day, the All About Vision website claims. However, the National Institute for Occupational Safety and Health, or NIOSH, recommends at least four short breaks during the day. To give your eyes a break, practice what some eye doctors call the "20-20-20" rule, the Mayo Clinic recommends. Once every 20 minutes, focus on an object at least 20 feet away for at least 20 seconds.
Another focus variation exercise involves looking at a faraway object for 10 to 15 seconds, then focusing on an object close by for 10 to 15 seconds. Alternate between the near and far objects 10 times. Blink frequently to maintain tear production to lubricate your eyes, All About Vision advises.
Use your finger as a focus point for a third exercise described by the the Division of Occupational Health and Safety, or DOHS. Hold up one finger a few inches from your eyes. Focus on the finger as you move your hand away from your body. Direct your focus to the distance, then focus again on your finger as you bring your hand back toward your body. Change your focus to an object at least 8 feet away. Repeat the exercise three times.
Eye Socket Massage
Another means of preventing dry eye is to massage your eye sockets, which stimulates tear production, the Mayo Clinic advises. Gently massage your upper eyelids against your brow bone, then alternate to massage your lower eyelid. Perform each motion for 10 seconds each.
While seated in front of your computer, place your elbows on your work surface, lean forward and cup your palms over your closed eyes. Inhale slowly and hold your breath for four seconds, keeping your eyes closed, DOHS recommends. Continue the exercise for 15 to 30 seconds.
Eye Roll Exercises
Close your eyes and roll your eyeballs up toward the ceiling, then down toward the floor, DOHS advises. Repeat the exercise three times, then open your eyes. Close your eyes again, then roll your eyeballs toward the left, then toward the right. Repeat the exercise three times, then open your eyes. Repeat this exercise three times also. Blinking and yawning also help to lubricate your eyes and keep them moist, DOHS claims.
