Computer Vision
More than half of all computer users experience eyestrain, headaches, blurred vision and other symptoms directly and indirectly related to increased, sustained nearpoint visual stress. This is now widely referred to as Computer Vision Syndrome. Visual stress may also underlie complaints of general body fatigue, reduced efficiency at work and higher error rates as the day progresses.

Behavioral optometrist have found that most of these symptoms are alleviated through a combination of correcting workstation conditions, posture, stress-relieving lenses prescribed specifically for computer use and sometimes through improving vision skills through vision training.

Visual Stress Checklist
  • Headache accompanying or following computer use
  • Eyestrain
  • Irritated Eyes
  • Blurred Vision
  • Slow refocusing when shifting from copy to screen to distance objects
  • Frequently losing place when moving eyes between copy and screen
  • Difficulty seeing clearly at distance after prolonged computer use
  • Occasional or frequent doubling of vision
  • Changes in color perception
  • Present lens prescription fails to relieve symptoms


    Workstation Suggestions

    Making changes in the set up of your work area can alleviate many vision problems associated with computer use.
    1. Keyboard, screen and copy should be at equal distance from the eyes.
    2. Screen should be slightly below eye level (20 degrees). Copy should be at the same level as the screen.
    3. Locate keyboard so wrist and lower arm are parallel to the floor.
    4. Chairs should provide proper back support and be adjustable.
    5. Adjust chair so that feet are flat on floor with thighs parallel to the floor.
    6. Adjust worktable so that legs and knees clear its underside.
    7. Screen brightness and contrast should be adjusted for maximum viewing comfort.
    8. Workstation lighting should provide a 10:3 ratio: screen characters 10 times brighter than screen background; room illumination 3 times brighter than screen background.
    9. An adjustable copy lamp aimed by the operator so as not to create screen reflections.
    10. Eliminate glare and reflections by moving or tilting the terminal. Overhead lights may need baffles. Try not to face toward windows or bright light sources.
    11. Users should face into an open space beyond the screen so as to enable them to take frequent 'look-away' breaks. Follow the 10 by 10 rule: For every ten minutes of computer use-look far off into the distance for 10 seconds.

    For many people, Visual Stress can be virtually eliminated by improving the workstation, using glasses designed specifically for computer use and through taking frequent 'look-away' breaks. For those whom this is not enough, visual training can help patients develop the ability to efficiently track and move both eyes together.
