Save Your Eyesight at the Computer

Tips for improving eyesight at the computer ...

"First, what does computer work have to do with eye health?

* For one, computer-induced eyestrain could damage your vision. When your eyes get accustomed to focusing for long periods of time at the same distance, the eye muscles become less flexible, and your vision can worsen, creating the need for stronger and stronger glasses.

* Focused computer work is a major cause of stress. Studies show that when people are concentrated on their screen, they stop breathing as much as they need to and blink about half as often as they should.

* Poor body positions create poor circulation, which means your eyes are getting less oxygen and nutrition than they need to stay healthy. The eyes and brain consume a third of the oxygen, and a quarter of the nutrients our body takes in.

* Computer eyestrain could cause the need for reading glasses in middle age. Especially if you are in your 30s and 40s, doing the exercises below can actually prevent or slow down middle-aged vision loss, or presybyopia, that causes mid-lifers to need reading glasses. People with reading glasses or bifocals have a difficult time at the computer, and often end up with chronic headaches and backaches. Reading glasses and computer work are a bad match.

So spare yourself the trouble by following these simple measures:

* Seven body positions. Most of us know these seven ergonomic Dos, but here they are, for review: (1) Line of sight should be 6 inches above the computer screen; (2) screen should be 18-24 inches from eyes; (3) feet flat on floor, no crossed legs; (4) knees slightly below hips; (5) shoulders down and relaxed; (6) wrists slightly below elbows; (7) fingers slightly below wrists.

* Use your lap. If your desk is too high and your shoulders scrunched, an easy way to give yourself relief, even if you don't do it all the time, is to put your keyboard directly on your lap. For most people, this will place their elbows, wrists, and fingers in the correct position. Remember: even doing this sometimes is better than never."    (Continued via Ezine Articles)    [Ergonomics Resources]
