Computer Vision Syndrome


By Richard Shaw

Bachelor of Science/ Bachelor of Optometry (Hons).


The common symptoms of daily computer use include eyestrain, irritation, redness, blurred vision, and double vision. Optometrists usually refer to this as Computer Vision Syndrome. Dry eyes is the main computer related symptom and is caused by a number of factors including a person unconsciously staring at the computer screen. Research suggests people blink up to 5 times less when using a computer. The lack of blinking in conjunction with working in an air conditioned environment means that mostly everyone suffers from dry eyes.


Most studies find that 70-95% of people who use a computer for 3 hours or more a day will experience the symptoms of computer vision syndrome to some degree.


The best thing for anyone suffering from Computer Vision Syndrome is to see your local Optometrist for a full eye examination. Otherwise basic measures to take include having a 1 minute rest break every hour where you get up from your desk, go to the bathroom or get a glass of water and as you do so have a look around, looking out a window is best. Also make sure your work space is set up as ergonomically as possible, this includes having your computer about an arms length from you, making sure the top of your monitor is in line with your eyes so that your eyes are always looking either straight or downwards. To reduce glare and brightness try to increase the contrast and decrease the brightness setting on your monitor and make sure not too much light is reflecting off your screen from a near-by window or bright light source.

Call your local optometrist now to discuss computer vision syndrome, it's effects and ways to alleviate it.

Stacey and Stacey Optometrists have 3 locations in the Townsville area, Stockland Shopping Centre, Willows Shoppingtown and Charters Towers.
