If I don't have symptoms of CVS, do I still need computer eyewear?
Maybe. According to a study at the University of Alabama at Birmingham School of Optometry, even computer users who are not experiencing computer vision syndrome symptoms might benefit from computer glasses.
The study found that computer workers with no visual complaints often experience reduced productivity and accuracy at the computer. So even if you don't notice eye strain or other symptoms of CVS, it's a good idea to get an eye exam from a computer vision specialist if you spend a good amount of time each day in front of a computer.
