A monitor is an essential part of our lives, but it needs to be used with care. Used incorrectly, the monitor can be responsible for a number of severe health problems. I another post, we look at how to position the monitor for the safest and most efficient use. Today I have some more points for you.
Avoid overuse: The most common cause of problems with the correctly positioned monitor is overuse.
According to research, people do not blink as often when they use the computer. This leads to dry eyes, which in turn causes fatigue and itchiness. Artificial tears will help to a degree, but if you’re having to use drops on a regular basis, chances are you are spending to much uninterrupted time at the computer.
Read Eye Care for some more suggestions to avoid eye strain.
Practice the 20/20/20 rule: Constantly focusing at the screen, which is always in the same position and distance from your eyes, may cause permanent harm to your eyesight or may harm your eye coordination. A recommended solution to this is the 20/20/20 rule: Every 20 minutes, take a break of at least 20 seconds, and focus your eyes on an object at least 20 feet away. There are free programmes available for download that will assist you with this. I use Workrave (click on link) and have the short breaks set to remind me to take a short break every 20 minutes.
Regulate the brightness of your screen: Do not work at the computer in a dimly lit room. Note: Your screen should be approximately as bright as the area behind it. Adjust the brightness of your screen if necessary during the day.
Adjust your text: Use a font size which is easy to read. Your text should be about twice the size that you need in order to be able to read it. Adjust the colour of your text. Generally, black on white is easiest on your eyes.
Clean your screen regularly. Be careful! Don’t just spray household window cleaner onto the surface and wipe. Different screens require different handling. Follow the manufacturer’s instructions. To my surprise, this is worth a whole blog on its own. Come back on Monday for more information.
