Computers have become part of our lives. We have become so dependent on computers at work and home for e-mail, internet access, word processing, number crunching, and graphic design.

As computer usage has increased, so have related vision problems. One reason is because your eyes need to work harder to focus on the computer screen for a prolonged period. Because of this intense focusing demand, even low amounts of uncorrected astigmatism or farsightedness make your eye muscles work harder. Studies have shown that prescription glasses, designed specifically for computer use, will decrease eyestrain and physical fatigue, and improve productivity.

Muscles that control eye movement and eye coordination, also get a workout at the computer as you scan the screen or surf the web for hours. Inefficient eye tracking can make it difficult for you to analyze spreadsheets and keep your eyes on the lines of text. Poor eye coordination can slow you down while reading the screen. Eyes that tend to drift apart create symptoms such as eyestrain, intermittent double images and headaches.

At The Vision Center, your vision will be evaluated whilst you look at a computer screen ! We have found that its best to evaluate our patient's vision in a situation closest to the one they want to be comfortable in. So, if your using a computer,we will evaluate your vision using unique software developed specifically for this purpose.

Another cause of computer-related eyestrain is dry eyes. We tend to blink less frequently while concentrating which diminishes eye lubrication. Dry eye symptoms include burning, itching, intermittent blur, or a "heavy eyes" sensation. This can usually be improved by using artificial tears, a humidifier , or nutritional supplements to increase tear production. If you or your employees spend an hour or more each day using a computer, having the fastest computer and latest hardware is not enough. An up-to-date computer prescription, and correctly balanced eye muscles, are necessary to optimize your comfort and productivity.

IMPORTANT: When you come for your vision evaluation, make sure to have measured your working- distance from your computer, and bring it with you to your evaluation.
