Blinking is very important when working on a computer; blinking moistens your eyes to prevent dryness and irritation. When working on a computer, people blink about 30% less than they normally would. The blinks also tend to be only partial lid closures. The tears that typically coat the front surface of the eye, evaporate more rapidly during these long non-blink phases which can cause dry eyes. If you experience dry eye symptoms, ask Dr. Landrio about artificial tear use. It is important to recognize that lubricating eye drops are not the same as those drops formulated to “get the red out.” The latter can indeed make your eyes look better but are not necessarily formulated to reduce dryness and irritation. To reduce your risk of dry eyes during computer use, try this exercise: Every 20 minutes, blink 10 times by closing your eyes as if falling asleep (very slowly). This will help to rewet your eyes.
