If you work on a computer all day and suffer eyestrain, headaches, neck and shoulder pain, and other symptoms, you may suffer from computer vision syndrome (CVS). Your eye doctor in Conway answers questions about CVS every day and has prepared this list of Frequently Asked Questions in order to help you understand more about this condition.
What is computer vision syndrome?
Computer vision syndrome is an umbrella term for eyestrain and other vision problems that may occur as the result of working on a computer all day.
How many people have CVS?
Computer eyestrain affects 70 percent of the 143 million Americans who work on a computer every day, according to the American Optometric Association.
Who develops computer vision syndrome?
Anyone who spends two or more hours on a computer each day can develop this vision problem. CVS can affect adults and children, but children can adapt to symptoms in a way that makes vision problems more difficult to detect.
What are the symptoms of CVS?
- Blurred vision
- Burning eyes
- Tired, red eyes
- Double vision
- Eye twitching
- Neck and shoulder pain
What causes computer vision syndrome?
Human eyes focus differently on computer text than on printed words. Printed letters have crisp, distinct edges that are easy to focus on. In comparison, letters on a computer screen have less contrast and definition, which makes it more difficult for your eyes to maintain focus.
How can I relieve or prevent CVS?
Move your computer screen so that it is 20 to 28 inches away and about 4 to 5 inches below your eye level. If you are using printed material and find yourself looking back and forth between the reference material and the computer screen, move the printed material where you can see it with minimal movement of your head.
Take frequent breaks to give your eyes a chance to refocus. The 20/20 rule works well for most people – every 20 minutes, focus on a faraway object for 20 seconds. Take a 15-minute break after two hours of continuous computer use.
Blink frequently to reduce dry eye. A person typically blinks about 18 times per minute but blinks only about one-fourth as often while on a computer.
Reduce glare, which makes your eyes work harder. Position your computer screen where it receives the least amount of glare from windows and lights. Purchase a glare filter for your computer screen.
Have your eyes checked by your optometrist.
Can an optometrist help?
Yes, our eye doctor in Conway can perform a computer vision exam to detect any problems associated with CVS. Depending on the results of your exam, our optometrist may prescribe computer eyeglasses that help your eyes focus on computer text and graphics that cause CVS. Our optometrist can also screen for other eye conditions to make sure your symptoms are from CVS and not the result of another condition.
