AOA recommends resting eyes periodically to avoid computer vision syndrome.
In continuing coverage from previous editions of First Look, WLEX-TV Lexington (9/26), an NBC affiliate, reported that hours spent “peering at computer screens, televisions, hand-held devices, cell phones,” and GPS monitors may lead to “dry eyes, irritation, blurred vision, double vision, headache, and tiredness.” To help avoid “this group of symptoms,” referred to as “computer vision syndrome,” the “American Optometric Association (AOA) recommends resting your eyes for 15 minutes after working continuously for two hours on an electronic screen. In addition, every 20 minutes, look up from the screen and refocus your eyes on a distant object.” In addition, computer users should “reduce the wattage in desk lamps and adjust window blinds to cut down on screen glare.” Some people “may want to try over-the-counter eye drops known as ‘artificial tears,’” which “are available as lubricated, saline, homeopathic, and other types. Using a humidifier may also help.”
In an “Insider Medicine in 60″ video segment on Insider Medicine (9/26), Susan Sharma, M.D., reported that, “according to researchers from the University of Ulster, most people blink about 15 times a minute, but staring at a computer screen can reduce that by up to two-thirds. Blinking spreads tears across the eye and removes irritants, and insufficient blinking can lead to a condition called ‘dry eye,’ which can cause infection and sight loss.”
