Dealing With Eyestrain
You have been sitting at your computer for hours. You have got your ergonomic workstation, so your arms and wrists do not hurt. You have got your ergonomic chair with built-in back support, so your back and shoulders do not hurt. And you have also accomplished all you set out to today. So you feel great. That is except for one thing...2 actually. Your eyes are killing you due to eyestrain.
Staring at the ScreenWhile many forms of work can lead to eyestrain, most work-related eyestrain today relates to extended hours in front of a computer monitor called computer vision syndrome (CVS).Our eyes are designed to constantly shift their focus between objects that are near and objects that are far away. Eyestrain can result when the eyes focus on a single, close up object for extended periods of time, exactly what working at a computer terminal usually requires.Related symptoms include:
- Blurred vision
- Soreness or pain in the eyeballs
- Watering eyes
- Dry or scratchy eyes
- Eyelids that feel heavy
- Neck or back pain
Eyeglasses May HelpHow can eyestrain and its related symptoms be avoided? First, have a yearly eye exam to make sure there are no problems with your eyes. If you wear eyeglasses you might discuss with your optometrist or ophthalmologist whether contact lenses or computer glasses may be helpful for you. Computer glasses are specifically designed for working at a computer monitor. If you wear bifocals, especially if you are over age 50, consider getting executive bifocals. These are bifocals with the top half of the lens focused specifically for the distance you sit from your computer monitor, and the bottom half of the lens focused for reading materials. You may also benefit from special bifocal computer reading glasses if the line on the bifocals is causing problems.
General Tips for Preventing EyestrainThere are a number of steps you can take to help avert or lessen eyestrain:
- Lighting—Make sure you have sufficient lighting at work. Avoid florescent lighting directly in your field of vision.
- Lubrication—Blink your eyes frequently to keep them lubricated or try eye drops. You can use a lubricating artificial tear product without preservatives. If you select one with preservatives, avoid using more than 4 times a day.
- Eye breaks—Give your eyes a break by following the 20/20/20 rule. Every 20 minutes, take your eyes away from the computer and look at something 20 feet (6 meters) away for 20 seconds. This will allow your eyes to refocus. You can also do other noncomputer-related work, like filing papers. Consider taking a walk outside or just close your eyes for a bit and relax.
- Air quality—Dry eyes can be prevented by using a humidifier, avoiding smoke, and turning down the thermostat in your work area.
- Massage—Massage your eyelids and the muscles over your brow, temple, and upper cheekbone. Do this once or twice a day.
- Sun protection—If you work outdoors, wear sunglasses that provide complete UV-ray protection.
- Rest—If the work you do involves driving a vehicle, pull over to rest your eyes at least once every 2 hours, more often if possible.
Relaxation ExerciseTo help your muscles and eyes relax, try this exercise that you can do several times a day:
- Place your elbows on your desk.
- With your elbows still on your desk, turn your palms so they face upward.
- Allow your weight to fall forward. Let your head fall into your hands.
- Your eyebrows should rest on the base of your palms and your fingers should be fingers extended toward your forehead.
- Close your eyes.
- Take a deep breath through your nose. Hold for four seconds then exhale.
- Continue deep breathing for 15-30 seconds.
