With so many professions being computer dependent, it’s nearly impossible for most folks to decrease the time they spend staring at a screen. So, what can you do to protect your vision?
1. Proper lighting: Whether reading a book or an illuminated digital screen, a desk lamp aimed at your workspace helps minimize eye strain.
2. Proper positioning: Setting your computer in a position so that you are looking downward several inches tends to be the most comfortable for the eyes. Also, try to minimize the amount of glare and reflections from lights or windows picked up by your screen.
3. Blink: It’s easy to get so caught up in what’s on our monitors that we stare excessively and forget to blink normally. Yet, the tears that wash over our eyes when blinking help prevent irritation and drying. So, try to be aware of whether or not you’re blinking and blink frequently.
4. Take regular breaks: If possible take a break from the screen every 20-30 minutes, looking at something more distant for half a minute or so. This shift in focus engages other eye muscles and gives the ones focusing on your monitor some time to relax.
5. Eye exercises: There are a number of exercises you can do to strengthen your eye muscles, including making figure eights with your eyes while keeping your head straight. Another exercise that requires you to alternate the focus of your eyes (thus engaging different muscles) is a little trickier: Point your index fingers toward each other, about an inch apart. Hold them about eight inches away from your eyes at eye level. Look over your fingers at a distant object while still visually being aware of your fingers. If you’re doing it right, you will see a little “hot dog” floating between your two fingers (can take a few tries to get it.) Refocus your eyes on your fingers. Repeat several times.
