Healthy Computing Tip # 414: Clear Vision
After working at the computer, are your eyes irritated? Approximately 33 to 37 percent of people experience eye irritation such as, itching, burning, dry eyes or difficulty focusing on distant objects after computer work. Keep your world in focus when you increase clear vision.
How to Increase Clear Vision:
Blink frequently when looking (or is it staring?) at the monitor. This helps because our blinking rate decreases approximately 70% when we focus on the screen as compared to when we relax. Remember to blink the end of every paragraph or with every mouse click.
Adjust the top of the monitor screen so that it is equal or lower than the height of your eyebrows. When looking straight ahead or upwards at the monitor, our eyes tear less and the corneal surface dries. When looking slightly down, our eyelids will sweep down the whole eyeball when you blink. This 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 to think or talk on the telephone. Green is a soothing color for the 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.
Adjust and correct other factors that influence vision such as glare, reflections and wearing the correct prescription glasses.
