This temporary vision condition is caused by staring at a computer screen for long periods of time without the proper eye protection. Common symptoms of computer vision syndrome include blurred vision, redness in the eyes, back or neck strain, dry eyes, double vision, and dizziness. The best way to protect your eyes, and eliminate the eye strain associated with extended computer use, may be computer glasses. Many of us wear glasses to correct some kind of vision problem.
These specialty glasses called task-specific are designed to meet the visual needs of the activity. Generally speaking, bifocals are not necessarily designed for computer work.
They tend to force the wearer to tilt the head back in order to focus on the screen while looking through the lower segment of the bifocal lenses. Many people will either lean in or lean backwards to find the right spot in their lenses where they can see best. Such a forced position can cause neck and shoulder pain and it can also cause arm and low back pain.
Depending on the individual's vision and type of work, there are several options while selecting computer-specific glasses, such as:. Monofocal or single-vision glasses designed for computer work will provide the appropriate optical correction for the working distance between the screen and the computer user's eyes.
This option allows users to view the whole screen with a minimum up-and-down head movement. The disadvantage of this option is that both distant objects and reading materials that are closer than the computer screen will appear blurry. Bifocal glasses can be prescribed so that the upper segment is set up for the screen distance and a lower segment for work that is closer than the screen reading distance.
The disadvantage of this option is that objects farther away than the screen are blurry. Bifocal lenses also distort images of objects in the peripheral zone of vision. Segmented lenses like bifocals and those mentioned below have a smaller area for viewing the screen. This means more up-and-down head movement may be required to view all parts of the screen.
While the American Academy of Ophthalmology AAO does not recommend any special eyewear for computer use, Kim says her patients who use computer glasses reported a noticeable reduction in digital eye strain, giving her reason to believe blue-light-blocking lenses help.
Especially before bedtime, computer glasses that filter blue light can make a difference. The AAO says digital eye strain symptoms caused by computer use are only temporary and will ease after you stop using or take a break from your devices. Some final tips on how to reduce digital eye strain? Sit up straight at your computer, increase the font size on your screen, and improve the ergonomics of your workstation to reduce your digital eye strain and the pain in your back and neck.
You can avoid digital eyestrain by simply giving your eyes a break at regular intervals, Coleman says. As we get older, our tear production declines and increases our risk for dry eyes. Blinking less frequently while on the computer exacerbates the problem, says Timothy G. Murray, M. You can avoid this by using artificial-tear eye drops to lubricate your eyes. If you find yourself needing to use drops more than four times a day, the AAO recommends buying preservative-free drops, as many people find the preservatives can irritate their eyes.
Another underlying cause of computer-related eyestrain is that your eyes are working hard to focus on words or images at a somewhat odd distance: A computer screen is farther away than you'd hold a book and closer than you'd be from your TV. But I haven't really found that helpful for my patients. The easiest solution in such cases is to simply increase the font size to a comfortable reading size on all of your screens, Coleman says.
Boosting the contrast on your monitors also can take the strain off your eyes, Coleman says. As we mature, we all start to develop cataracts — a yellowing or clouding of the lens of the eye. Too much glare — light that is brighter than the eyes can comfortably handle — from your screens can also lead to eyestrain, Coleman says. Finally, a new monitor can do wonders for tired eyes, especially if you're staring at a small laptop screen all day.
