Computer vision syndrome (CVS), also referred to as Digital eye strain (DES), is a group of eye and vision problems caused by prolonged use of electronic devices. The American Optometric Association (APA) defines DES as a group of eye and vision-related problems caused by prolonged computer, tablet, e-reader, and cell phone use. Currently, for more than 20 years, DES has been recognised as a public health issue, and the terms DES are also used to describe the condition, attributed to the wide range of digital devices associated with potential problems.
