Computer Vision Syndrome: Prevention and Complications

Prevention Tips

Some important factors in preventing or reducing the symptoms of CVS have to do with the computer and how it is used. This includes lighting conditions, chair comfort, location of reference materials, position of the monitor, and the use of rest breaks
  • Have your vision checked regularly.
  • Place the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the centre of the screen and 20 to 28 inches from the eyes.
  • Position the computer screen to avoid glare, particularly from overhead lighting or windows. Use blinds or drapes on windows and replace the light bulbs in desk lamps with bulbs of lower wattage.
  • Use a screen glare filter if the glare from light sources cannot be minimized.
  • Adjust the seating position in such a way that the chair height should be so your feet rest flat on the floor. Place your hands on the arms such that the wrists should not rest on the keyboard when typing.
  • Try to rest your eyes when using the computer for long periods. Rest your eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow your eyes a chance to refocus.
  • To minimize your chances of developing dry eye when using a computer, make an effort to blink frequently.
  • The documents should be located above the keyboard and below the monitor. Position the documents so you do not need to move your head to look from the document to the screen.
