COMPUTER VISION SYNDROME (Digital Eye Strain) is a term that describes vision-related problems and other symptoms caused by prolonged computer use. More and more people are increasingly getting dependent on computers in their daily routine and this has brought about a number of health concerns like ocular discomfort, muscular strain and stress.

CVS affects most people who work for more than 2 hours a day in front of the computer screen, especially children and adults above 40 years of age. Those who has refractive errors, binocular vision problems, focusing disorders and dry eye disease are more likely to have problems. The extent to which an individual may experience symptoms is largely dependent upon their visual abilities in relation to the visual demands of the task being performed. These unique characteristics and high visual demands of computer work lead to eye-related symptoms.
