Computer vision syndrome.

Since computer use is such a visually demanding task, vision problems and symptoms have become very common in today’s work place . Most studies indicate that computer operators who view their video display terminals (VDT) report more eye related problems than non VDT office workers. NIOSH Survey (National Institute of Occupational Safety and Health) has reported that visual symptoms occur in 75-90 % of VDT workers as opposed to 22 % musculoskeletal disorders (carpel tunnel syndrome) in computer users .
