Today is graduation day (and the last day of school) at the high school where Mom teaches. It's a furry long day for Mom, so I'll have hours of unsupervised time on the computer to visit bloggies and catch up on all of the latest in the blogosphere. All of that computer time will certainly wreak havoc on my beautiful amber peepers, so I present you with this week's Thursday Thirteen (plus one):
The American Optometric Association's Symptoms of Computer Vision Syndrome
1. tired eyes
3. sore eyes
4. periodic blurred near vision
5. occasional blurred distance vision
7. dry eyes
8. slowness in changing the focus of your eyes
9. red eyes
10. burning eyes
11. contact lens discomfort
12. changes in color perception
13. glare sensitivity
... and the plus one
14. excessive tearing
Obviously, the easiest way to prevent CVS is to stop using the computer! But, as that is simply not an option, so here are 5 tips to help you monitor your natural monitors: your eyes.
1. Make sure your workstation, whether on the job or at home, is set up ergonomically. A poorly located computer screen causes awkward body positions. Viewing distance of 20-28 inches is most common.
The center of the computer screen should be 4-9 inches below your eyes, because your eyes work best with a slight downward gaze.
2. Eliminate glare in your work area. Glare is an all-too-common cause of eyestrain and eye fatigue. Lights should not shine directly on the computer or into your eyes. You may need to use a low-wattage bulb.
3. Adjust your screen as the best visibility is attained with black
characters on a white background. You can also adjust your brightness/contrast controls, and use a larger
4. Take a break. It's easy to lose track of time at the computer. Always remember the 10-10-10 rule and at the very minimum take a break at least once an hour for about 10 minutes and blink frequently. Computer use can also cause an increased rate of tear evaporation.
5. Stay healthy. Although you can relieve dry, itchy eyes with artificial tears from the drugstore or supermarket, it's best not to rely on them. A better way to prevent dryness is to stay hydrated with good old-fashioned H2O. Of course, eating your beta-carotine-rich foods is always good for maintaining eye health, and a Japanese study suggests that supplementation
with the amino acid taurine appears to alleviate vision fatigue.
