What Is Computer Vision Syndrome ?
Many of us have jobs that require us to stare at computer screens for hours at a time. That can put a real strain on your eyes.
Eye problems caused by computer use fall under the heading computer vision syndrome (CVS). It isn’t one specific problem. Instead, it includes a whole range of eye strain and discomfort. Research shows that between 50% and 90% of people who work at a computer screen have at least some symptoms.
Working adults aren't the only ones affected. Kids who stare at tablets or use computers during the day at school can have issues, too, especially if the lighting and their posture are less than ideal.
How Do Computers Affect Vision?
CVS (Computer Vision Syndrome) is similar to carpal tunnel syndrome and other repetitive motion injuries you might get at work. It happens because your eyes follow the same path over and over. And it can get worse the longer you continue the movement.
When you work at a computer, your eyes have to focus and refocus all the time. They move back and forth as you read. You may have to look down at papers and then back up to type. Your eyes react to images constantly moving and changing, shifting focus, sending rapidly varying images to the brain. All these jobs require a lot of effort from your eye muscles. And to make things worse, unlike a book or piece of paper, the screen adds contrast, flicker, and glare. What's more, it is proven that we blink far less frequently when using a computer, which causes the eyes to dry out and blur your vision periodically while working.
You’re more likely to have problems if you already have eye trouble, if you need glasses but don't have them, or if you wear the wrong prescription for computer use.
Computer work gets harder as you age and the natural lenses in your eyes becomes less flexible. Somewhere around age 40, your ability to focus on near and far objects will start to go away. Your eye doctor will call this condition presbyopia.
What Are the Symptoms?
There's no proof that computer use causes any long-term damage to the eyes. But regular use can lead to eye strain and discomfort.
You may notice:
--Blurred vision
--Double vision
--Dry, red eyes
--Eye irritation
--Headaches
--Neck or back pain
If you don’t do anything about them, it could affect more than your eyes. You could also have issues with your work performance.
How Is It Treated?
A few simple changes to your workspace can improve your symptoms and prevent new problems:
♦ Cut the glare. Change the lighting around you to reduce the effect on your computer screen. If light from a nearby window casts a glare, move your monitor and close the shades. Ask your employer to install a dimmer switch for the overhead fixtures if they're too bright, or buy a desk lamp with a moveable shade that casts light evenly over your desk. You can also add a glare filter to your monitor.
♦ Rearrange your desk. The best position for your monitor is slightly below eye level, about 20 to 28 inches away from your face. You shouldn't have to stretch your neck or strain your eyes to see what's on the screen. Put a stand next to your monitor and place any printed materials you're working from on it. That way, you won't have to look up at the screen and back down at the desk while you type.
♦ Give your eyes a break. Follow the 20-20-20 rule. Look away from the screen every 20 minutes or so and look at something around 20 feet away for about 20 seconds. Blink often to keep your eyes moist. If they feel dry, try some eye drops.
♦ Tweak your settings. You don't have to live with the factory-installed presets if you're uncomfortable. Adjust the brightness, contrast, and font size until you find what’s best for you.
♦ Visit your eye doctor regularly for exams and to keep your prescriptions up to date. Let him know about any problems you have. You may need glasses or contact lenses. He’ll decide if you can wear your regular glasses for computer work or if you need a special pair. He might prescribe a single or bifocal lens, or tinted lens material to boost contrast and filter out glare.
Get your kids' eyes checked, too. Make sure any computers they use are set up at the right height and in the best light. Encourage them to take frequent breaks from the screen to give their eyes a rest.
How to Avoid Computer Eye Strain
Computers can make us more productive, but the bad news is that too much screen time can also lead to something called computer vision syndrome (CVS). Recognizable as that tired, strained feeling your eyes get after a day in front of a computer screen, CVS affects some 64% to 90% of office workers.
The condition likely doesn’t cause permanent eye damage, but it can still affect computer users’ comfort. The most common symptoms of CVS include eye strain, redness, irritation or dryness, a burning feeling in the eyes, blurred or double vision after computer use, headaches and neck and shoulder pain.
Several factors increase the likelihood of CVS, including uncorrected vision problems, dry eyes, glares on the screen, poor lighting, poor posture and even the angle of the monitor. Another big factor is incorrect prescriptions: almost 71% of people reporting symptoms of CVS wear eyeglasses or contact lenses.
If computer screens are proving a pain in your eyes, here are some guidelines to help ease symptoms:
--Have your eyes checked regularly. If you need a new or changed prescription but don’t have it, using a computer will be difficult, period.
--Reposition the computer. The screen should be about an arm’s length away and positioned directly in front of your face, not off to the side. Position the monitor so its center is 4 to 8 in. below your eyes, which allows the neck to relax while you read and type.
--Follow guidelines for good posture. It’ll reduce strain on the back, neck and shoulders.
--Ensure proper lighting. Try the visor test to determine if current lighting is a problem: look at the monitor and cup your hands over your eyes like a baseball cap. If your eyes immediately feel better, then the lighting should be changed. Experiment with brighter and dimmer lighting, as well as the angle of the lights, to find what’s most comfortable for your eyes.
--Reduce glare. Installing anti-glare filters on the monitor, adjusting window shades and changing the screen’s contrast and brightness can help reduce glare and reflections.
--Blink frequently. It should prevent dry eyes. If that doesn’t work, consider using lubricating eye drops. Also make sure air vents aren’t blowing on your face (this can dry out the eyes), and use a humidifier if the room is super dry.
--Take regular work breaks. Stand, stretch or just look off into the distance, away from the computer, every 15 minutes or so to give the eyes a break.
--Clean the monitor regularly. Dust can decrease screen sharpness, making the eyes work harder.
--Try computer glasses. Unlike everyday eye wear, they’re designed specifically for looking at computer screens.
--Consider optometric vision therapy. Some computer users have issues with eye focusing or coordination that aren’t corrected by glasses or contacts. Vision therapy consists of doctor-prescribed activities designed to improve visual functioning (think of it as a workout for the eyes — though no guarantees as to calorie burn).
