The American Optometric Association defines Computer Vision Syndrome (CVS) as eye and vision problems related to computer use. The symptoms of CVS include tired eyes, eyestrain, sore eyes, periodic blurred near vision, occasional blurred distance vision, headaches, dry eyes, slowness in changing the focus of your eyes, red eyes, and burning eyes. Bausch & Lomb reports that nearly sixty million people suffer from eye or vision problems due to computer work. One million new cases are reported each year. See the Computer Vision Center for more information about how the computer affects your eyes and how to protect your vision.
