According to the American Academy of Ophthalmology, computer vision syndrome (CVS) is caused by focusing on a screen for hours. In most cases, symptoms of CVS occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform them. Many of the visual symptoms experienced by users are only temporary and will ease off after taking a break from computer screens and digital devices.
