How to prevent computer eyestrain?

That was a very practical tip you gave. I might buy post-it notes and start pasting them in my monitor. Here are few additional tips to prevent eye strain when we are using our PC monitors- (source: http://ergonomics.about.com/od/eyestrain/tp/eyestrainprev.htm) 1. The best way to prevent eye strain is to not use them as much. With your eyes that may be difficult to do. Luckily your eyes use more than one set of muscles. That means you can relax one set while using another. Shift your focus from near to far on a regular basis. Shift focus from up close to at least 20 feet away. 2. Use non-reflective interfaces whenever possible. Like reading from paper instead of a computer screen. When you have to use a screen make sure it is at a 90 degree angle from any direct light source. Use indirect or reflective lighting whenever possible. Try switching your monitor to a flat screen technology. They are not as reflective. Use anti-glare technology. Use an anti-glare filter on monitors. If you are at your computer look out the window for a minute. 3. Ensure there is good contrast. More contrast makes edges more discernible so the eyes don't have to focus as much. Keep overall lighting levels at a moderate level so there is good contrast around you but glare does not become a problem. Use task lighting to aid eyesight at specific tasks. Adjust the contrast setting on monitors and screens to the best effect. 4. Eye strain is actually the strain of the muscles controlling the eyes. Strengthening these muscles with a series of eye exercises will go a long way to preventing eye strain.
