  People who spend more than two hours on a computer each day will experience symptoms of CVS or Computer Vision Syndrome.
  Computer Vision Syndrome affects millions of office workers, students, and retired people who are computer users. Only when they eyes can clearly focus at the plane of the computer screen can the patient experience relief from the fatiguing effects of Computer Vision Syndrome.

Epidemiology

• Listen / Stop:
  - According to the Bureau of Labor Statistics, over 50 percent of all workers in the United States use a computer at their job.
  - According to the National Center for Education Statistics (NCES), about 90 percent of children and adolescents ages 5 to 17 use computers at school or at home. - About 25 percent of 5-year-olds use the Internet, and this number rises to over 50 percent by age 9 and to at least 75 percent by ages 15 to 17, according to NCES.

  Vision problems: Vision problems can include blurred vision (both near and far), difficulty changing focus, double vision, glare, flickering sensations, and temporary changes in color perception.
  Eye problems: Eye problems can include redness, burning sensation, soreness, stinging, itchiness, dryness, excessive tearing, eye fatigue, eyestrain, light sensitivity, and contact lens discomfort.
  General discomfort: General discomfort symptoms can include headaches, neck tension or pain, shoulder tension or pain, back pain, pain in arms or wrists, excessive fatigue, irritability, and drowsiness.

Treatment

• Listen / Stop:
  In about 1995, the American Optometric Association published its own ergonomic guidelines for the visual comfort of VDT users.
  What AOA suggests is as follows:
  Working distance from eye to screen should be set between 20" and 26".
  Viewing angle for the screen should be 10 degrees to 15 degrees below straight-ahead gaze position. That would be equivalent to about a 10" drop from the straight-ahead gaze line directly above the screen to the center of the screen.
  Room lighting should be free of glare sources as much as possible. Screen anti-glare cover filters should be used where necessary (glass filters only; do not use plastic mesh filters).
  Cover or mask windows to prevent glare from sunlight, and place computer screens at 90 degrees angles to windows whenever possible.
  Reduce room lighting so that screen brightness and contrast can also be reduced to more comfortable levels. Use task lighting at each desk to illuminate copy work.
