Help for Computer Eyes
by Michael J. Lipson, O.D.
There is no evidence that VDT's are harmful to the eyes. Nevertheless, as more and more of us are using computers for longer periods of time, we find more people experiencing eye fatigue after using the computer.
Symptoms of computer eye fatigue include:
- blurring of print on the screen
- burning/dryness/tearing
- headaches
- difficulty focusing when looking away from the screen
- eyestrain or "tired eyes"
Have a complete eye examination
- People with slight prescriptions that are not worn experience added strain because it takes extra effort to maintain focus: wear your best prescription
- Special computer glasses can be prescribed to ease the strain of focusing at the computer distance
- Bifocals and computers don't always go together; there are many helpful alternatives:
- single vision lenses prescribed specifically for your working distance
- specially designed bifocals, top part for the computer and the lower part for reading written text
- computer-specific trifocals that have a very large mid-range segment
- special progressive lenses
- custom designs based on your unique needs
Create the proper workstation
- Monitor should be at 20-26" from your eyes set below the height of your eyes
- A document holder should be at the same height as the monitor
- Windows should be to the side, not in front of you or at your back (this minimizes reflections from the screen or brightness issues)
- If glare or reflections are still bothersome, use an anti-glare filter
- Keep the screen clean and use larger font sizes
Use eye lubricants
- We don't blink as often when doing visually intense activities; use artificial tears without preservatives
- Try wearing glasses rather than contact lenses (contact lenses can dry out too)
Take periodic breaks
- It is very helpful to take a 2-3 minute break from the screen every 30 minutes
- At these breaks, focus on something in the distance and get up and walk around
