Computer Vision Syndrome

In the present era, the use of the computers in the home and office has increased and is associated with increased health risks especially for eyes. The human eyes were designed for more of near sight work . We sailed through centuries with minimal difficulties as the eyes could adapt to the changes in our near tasks as this requirement was not that much. One eye problem, called Computer vision syndrome is afflicting more and more people as these people are constantly in front of computer screens and hence have requirement of more near work. This paper reviews the principle ocular problems related to prolonged computer use and management of these problems. Accommodation and  vergence responses to electronic screens appear to be similar to those found when viewing printed material, whereas prevelance of dry eye symptoms is greater during computer use. This is probably due to dynamics of the computer screen and decrease in blink rate due to constant viewing of the monitor positioned in primary gaze leading to increased corneal exposure and hence the multitude of ocular problems.
