If your job or hobbies or both involve spending a lot of time in front of a computer, you may be suffering from CVS, computer vision syndrome. Betabeat.com reports that the American Optometric Association now recognizes CVS as "a group of eye and vision-related problems that result from prolonged computer use." The level of discomfort appears to increase with the amount of computer use. Symptoms are eye strain, headaches, blurred vision, dry eyes and pain in neck and shoulders. The obvious remedy? Spend less time on the computer, game station or tablet. Or you can opt for "advanced computer eyewear" which various makers claim will improve contrast, comfort and focus so you can spend even more hours staring at screens.
