HEALTHY COMPUTING EMAIL TIP 563: CLEAR VISION
After working at the computer, do your eyes feel tired and irritated?
Approximately 35 percent of people experience eye irritation, such as itching, burning, dry eyes or difficulty focusing on distant objects after computer work. Take care of your eyes, look to your health and increase CLEAR VISION.
HOW TO INCREASE CLEAR VISION:
Blink frequently when looking (or is it staring?) at the monitor.
Consciously blinking counteracts the tendency to stare (our blinking rate decreases approximately 70% when concentrating on the monitor). Remember to blink at the end of every paragraph or with every mouse click.
Adjust the top of the monitor screen so that it is equal to or lower than your eyebrows. When looking straight ahead or upward at the monitor, our eyes tear less and the corneal surface dries. When looking slightly down, our eyelids will usually sweep down the whole eyeball when blinking, which moistens the cornea instead of only the upper eyeball.
Look out a window (if possible) at a distant tree or lawn when taking a break, when talking on the telephone or when thinking about a task. Green is a soothing color for our eyes. If you don't have access to a window, decorate your work area with green plants that you can look at during your vision breaks.
Have your vision checked since clarity of vision also depends upon your ability to focus your eyes to see the screen. Bifocals and progressive lenses usually force the wearer to look through a narrow slit to see the material in focus, which tends to stiffen the neck. Special computer glasses may significantly reduce eye and neck strain.
