Q: I have a headache and sore eyes from typing at my computer all day. What can I do?

A: Sore eyes and headaches are just two symptoms of Computer Vision Syndrome (CVS). CVS is a relatively common problem occurring in an estimated 70-75 per cent of computer users.

Symptoms of Computer Vision Syndrome
CVS can can result in one or more of the following symptoms:

  • Uncomfortable, painful, irritated eyes
  • Blurred vision
  • Headaches: vision-related headaches often occur toward the front of the head.
  • Double vision
  • Dry, irritated eyes
  • Neck/shoulder/back aches from leaning forward to see better.

What you can do to feel better
The good news is that computer vision problems are preventable and solvable.

  • Get regular eye examinations to determine if you need corrective or specialized lenses.
  • Ensure your monitor is located directly in front of you, approximately arm's length away. For most workstations a 17-inch to 19-inch monitor is appropriate. Remember, the further away the monitor is, the bigger it should be.
  • Consider a flat screen monitor. This will eliminate flicker and help minimize glare.
  • Increase the font size. Use at least 12 point, or larger, if you continue to experience sore eyes.
  • Evaluate your lighting. When reading from the computer you require a lower level of room light because the computer monitor emits its own light.
  • Control outside light with blinds to prevent glare.
  • Ensure that humidity in your office is at 40 per cent or consider using a humidifier. Your eyes require moisture and we tend to blink less frequently when looking at a computer monitor.

Give your eyes a workout
Lastly, here are some exercises you can do to keep your eyes healthy at work:

  • Blink frequently to help keep your eyes moist
  • Close your eyes and cover with them with the palms of your hands. Rest your eyes in darkness for approximately one minute
  • Change your focal point every 20 minutes. Take a break and stare at something in the distance for 20 seconds.
