Computer Vision Syndrome

According to the American Optometric Association, 175 million people use a computer every day. And we can expect that number to increase every year as more and more jobs will require the use of computers. While computers enable us to be more efficient and productive, this can come at a price. Researchers have recently identified a condition called Computer Vision Syndrome (CVS). Typical symptoms include: eyestrain, headaches, slow focusing, tired eyes, neck and shoulder pain, and blurred vision at distance. CVS occurs because the human visual system is not designed for long hours of computer viewing. In addition, the letters on a computer screen are harder to focus than printed text as they are composed of pixels - tiny dots of light with blurry borders. Hence, eyes have to work extra hard to clear words and images on a computer screen.

To better identify patients susceptible to CVS, we use the PRIO Computer Vision Tester. This instrument allows the doctor of optometry to precisely determine if a patient would benefit from a computer spectacle prescription. When prescribed, computer glasses allow your eyes to relax and be more comfortable at the computer. Research has also shown that employees who use computer glasses make fewer mistakes!

With computer glasses, the ideal power for computer work is placed directly in front of the pupil, allowing patients to look straight-on at the monitor (as opposed to conventional progressive addition lenses where it is necessary to tilt the head back to find the optimal power for the computer monitor). Patients frequently comment the elimination of this head tilt eliminates their neck and shoulder pain.

So if you work more than two hours a day on a computer, make sure you ask Dr. Ward about this exciting new spectacle option.
