Computer Vision Syndrome

Abstract

Computer vision syndrome (CVS) is defined by the American Optometric Association as a “complex of eye and vision problems related to near work which is experienced during or related to computer use.” As computers are a part of our everyday life, more people are experiencing a variety of ocular symptoms related to computer, tablet, e-reader, and cellular phone use. Many people experience eye discomfort and vision problems when viewing digital screens for long periods of time. The unique characteristics and high visual demands of computer and digital screen viewing make many individuals susceptible to the development of vision-related symptoms. The level of discomfort appears to increase with the amount of digital-screen use. Signs and symptoms include digital eyestrain, tired eyes, irritation, redness, blurred vision, and double vision that are collectively referred to as CVS. However, the major contributor to CVS symptoms, by far, appears to be dry eyes. This article discusses the causes, diagnosis, and treatment modalities that are currently available.
