Computer vision syndrome (CVS) is the result of extended exposure to digital screens like computers, tablets and cellphones. On average, a worker spends around 7 hours a day in front of a computer.
In this post, your local eye care center, Guilford Eye Center, discusses what you need to know about computer vision syndrome.
Computer Vision Syndrome
CVS occurs due to repetitive eye movements. When working at a computer, your eyes constantly shift their focus and move back and forth as you read. Your eyes adapt to the images viewed on the screen so the brain can comprehend the images. These motions, including the flicker, contrast and glare from the screen, can put a lot of straing on your eyes.
You are more prone to experience CVS if you aren’t wearing the right prescription glasses or have an existing eye condition. However, for some, even if they are wearing prescription eyeglasses or contact lenses, it can still be difficult to see what’s on the screen. They tilt their heads or bend toward the screen to see clearly. This may be because their eyewear isn’t meant for computer use. Poor posture can make computer use more uncomfortable.
Computer use hasn’t been proven to cause permanent damage to the eyes, but too much use can cause eye discomfort. The common symptoms of CVS include blurred vision, double vision, dry or red eyes, eye irritation and neck or back pain. The latter symptoms don’t just affect your eyes, but they can also lower your productivity.
Lighting can cause glare on your computer screen. You can either move your monitor away from windows or overhead lighting. You can also place a glare filter on the screen.
The monitor is best positioned 15 to 20 degrees below eye level, around 20 to 28 inches away from your face. Place your reading materials where you won’t have to move your head back and forth to read the screen. Make sure that you’re seated comfortably while working.
Blink frequently to keep the eye surface moist and prevent dry eyes. Give your eyes a break by following the 20-20-20 rule, where for every 20 minutes, you look away 20 feet away from the screen for 20 seconds.
