Computer Vision Syndrome

Eric L. Barnes explains what Computer Vision Syndrome is, and what you can do to avoid it.

In no point in human history have people been staring at bright screens just a few feet from their face like they are today. Computer vision syndrome or CVS (not to be confused with Concurrent Versions System) is one side effect to this, and it’s affecting millions of people.

The National Institute of Occupational Safety and Health reports computer vision syndrome affects about 90% of the people who spend three hours or more a day at a computer, which means almost everyone in our industry is susceptible.
