Studies have found no indication that working on a computer screen causes permanent vision problems. Short-term problems, such as tired, irritated or watery eyes, do bother the majority of people who work at computers, but these problems can usually be corrected by wearing a special pair of glasses for computer work, adjusting lighting in the workplace and altering the position of the computer screen.

Correct vision problems

One of the easiest ways to prevent eye fatigue and discomfort is to see a vision specialist.

Minor visual problems, such as astigmatism or imbalances between the eyes, can be corrected by wearing corrective lenses, and you'll greatly increase your comfort. If you don't have to see distant objects clearly while at the computer, wearing bifocal lenses with the top adjusted for the computer screen and the bottom adjusted for reading is ideal

If your distance vision must be clear while working at the computer, bifocal lenses with the upper part adjusted for distance and a large bottom part adjusted for the computer is recommended. As an alternative, a progressive lens with a large middle section for computer work could be used.

Some people can comfortably use bifocal contact lenses when working at a computer, but in most cases, glasses will provide greater comfort and clearer vision.

Increase your comfort

The following steps can further reduce your eye discomfort and fatigue.

  • Place the computer straight in front of you, not off to the side.
  • Place the screen at right angles to any windows to minimize glare.
  • Adjust the screen angle to minimize reflections from overhead lights or desk lamps.
  • Use drapes, shades, or blinds to control window lighting and glare. Vertical or horizontal blinds will direct light away from you and the computer.
  • Keep the screen brightness the same or brighter than the brightness of other objects in the room.
  • Set your computer to display black characters on a white background.
  • Use an adjustable copy holder to keep reference material at the same height and distance away from you as the computer screen. This eliminates the need to change eye focus when looking from one to the other.
  • Use a glare-reduction filter to enhance screen contrast and increase character legibility. Use a three-sided computer hood if glare continues to be a problem.
  • Wipe the screen often with an anti-static cloth.
  • Take periodic rest breaks. Every 15 minutes or so, look up and focus on a distant object for about two minutes. Blinking frequently and using artificial-tear eye drops to relieve dryness and irritation can also help.

  • PHOTOS: Madison store helps collect hundreds of Teddy bears for police

    MADISON, Wis.--A west Madison store is part of an effort to collect hundreds of stuffed animals to donate to six police departments in Southern Wisconsin.

    Todd Merryfield, owner of The Learning Shop at 714 S. Gammon Road, said the store is collecting the bears for officers who use them to help comfort children with whom police come in contact.

    "This is a great way to support what (police) do," Merryfield said. "Those are the kids that need something like this to reassure them, calm them down, and let them know that things are all right."

    Nearly 500 plush animals were donated Tuesday, a Learning Shop spokeswoman said. The Madison store's effort is part of a larger initiative through the Bears for Humanity organization.
