COMPUTER VISION SYNDROME
By Deidre Benson

About Me
  • My name is Deidre Yvette Benson
  • I am a senior at Virginia Wesleyan college
    majoring in Social Sciences with a concentration
    in Health and Human services.
  • I have been married to Reverend Cory Benson for
    four years.
  • At the moment we have no children, with the
    exception of one God child.
  • I was born in Brooklyn, new York, but I now
    reside in Virginia beach, Virginia.

3
What is Computer Vision Syndrome?
  • This condition most commonly occurs when the
    viewing demand of the task exceeds the visual
    abilities of the video display terminal (VDT)
    user.
  • The American Optometric Association defines CVS
    as that complex of eye vision problems related
    to near work which are experienced during or
    related to computer use.

4
What are the symptoms of Computer vision Syndrome?
  • Eyestrain
  • Headaches
  • Blurred vision
  • Dry and irritated eyes
  • Neck ache and backache
  • Sensitivity to light
  • Double vision

5
Other symptoms of Computer Vision Syndrome
  • Slowness in changing the focus of your eyes
  • Red eyes
  • Contact lens discomfort
  • Changes in color perception
  • Glare sensitivity
  • Excessive tearing

6
CVS The Problem
  • Working at the computer all day is a physically
    demanding job. When working at the computer all
    day long the eyes receive the worst punishment.
    When working on the computer one full day, your
    eyes perform a near-task an amazing 25,000 times
    that matches one heartbeat.

7
CVS The problem continues
  • When using the computer your blink rate decreases
    by a drastic 70 percent. Generally speaking
    means that instead of blinking an average of 14
    times per minute, you are now blinking 7 times
    per minute.

8
The solutions to Computer Vision Syndrome
  • Install a glare guard, an optically coated glass
    anti-glare filter. The high resolution, high
    contrast filter increases view ability.
  • Have a thorough eye exam
  • Install a screen or partition behind your
    computer to reduce both outside light and
    overhead glare.

9
Other cures for Computer Vision Syndrome
  • Use a non-reflective paint or coverings on the
    walls facing the computer.
  • Use equipment with brightness controls or add
    such controls to your screen
  • If possible, relocate lamps that causes
    reflections on the screen.
  • Add dimmer switches to overhead lights or use
    coverings on fluorescent lights.

10
Other solutions to Computer Vision Syndrome
  • Make sure there is sufficient light to read hard
    copy without straining.
  • Adjust the height of your desk or chair so the
    middle of the computer screen is about 20 degrees
    below eye level. The screen itself should be 16-
    30 inches from your eyes.
  • Use a stand for hard copy so that source
    documents and the computer screen are at roughly
    equal distance from the eyes.

11
Other solutions to prevent CVS
  • Be sure to blink frequently and take visual
    breaks. A good rule of thumb is 20/20, 20
    minutes, look 20 feet away for 20 seconds.
  • Place reference to typing materials close to the
    computer screens.
  • If your eyes are dry or irritated, use eye drops
    to moisturize and lubricate
  • If any symptoms are worse of you sight is
    deteriorating, make an appointment to see your
    eye care professional.
