Computer Vision Syndrome

Computer vision syndrome: causes and cures

Do you spend a lot of time at your computer? The average Canadian spends seven hours a day looking at a desktop, laptop, tablet, e-reader or cell phone. As you can imagine, that much time in front of a screen can place a fair amount of strain on your eyes. And it’s been given a name: computer vision syndrome (CVS).

An eye exam by our optometrists at one of our three Calgary eye clinics; will help determine whether you suffer from CVS and provide you with solutions.

Causes of CVS

The main causes of CVS include:

  • Poor posture
  • Incorrect viewing distance
  • Glare
  • Poor lighting
  • Uncorrected vision issues

If you have CVS, it’s likely due to one or more of these elements. The screen plays a particularly big part. Letters on screens aren’t as sharply defined as those on paper and there is greater contrast between letters and background.

Symptoms of CVS

  • The main CVS symptoms include:
  • Shoulder and neck pain
  • Headaches
  • Blurred vision
  • Dry or strained eyes

To help determine if you suffer from CVS, book an eye exam with our optometrists at one of our three Calgary eye clinics.

What you can do about CVS

There are a number of practices and measures you can take that will alleviate CVS symptoms:

  • Take a break. Follow the 20-20-20 rule. After 20 minutes of screen time, stop and look at something at least 20 feet away for 20 seconds. In addition, after two hours of looking at a screen, rest your eyes for a full 15 minutes.
  • Screen location and comfort. As a rule, having the screen 15 to 20 degrees below your eye level and 50 to 65 cm away will be easiest on the eyes. Also ensure your sitting posture is comfortable with both feet placed flat on the floor.
  • Glare. Place your screen in such a way that light from windows and lamps do not produce glare. Use window shades if necessary and bulbs with lower wattage. Anti-glare screens and filters are also available.
  • Reference material location. Ideally, place your reference material so you don’t have to move your head between screen and document.
  • Yearly eye exams help in vision care. Often, CVS will be exacerbated because you suffer from uncorrected vision problems, or the contact lenses or glasses you normally wear are inadequate for extended computer screen viewing. To see if this is the case, contact our optometrist who specialize in eye health and vision care in Calgary and the surrounding cities.
