Screens are an absolute necessity for modern living. We work in front of computers, we use our smartphones for hours each day, and we often relax in front of the television. If you stare at screens for an extended period of time you can develop a temporary condition called computer vision syndrome.
Computer vision syndrome is quite common. The symptoms are vertigo, dry eyes, eye strain, double vision, and headaches. If you use computers and screens regularly you have likely experienced computer vision syndrome.
