Using a computer for an extended period can take a toll on your eyes. Your eyes will become more fatigued the longer you stare at a computer monitor. And considering that most office workers spend over seven hours per day using a computer, eye strain is a real concern. The good news is that you can protect your eyes when using a computer by following a few simple tips.
Turn Down the Brightness
Whether you use a desktop or notebook computer, you should be able to adjust the brightness of the monitor. Brighter monitors are more likely to strain your eyes than dimmer monitors. Therefore, you should try turning down the brightness of your computer monitor. With a dimmer monitor, you'll be better protected against eye strain and other computer-related eye conditions.
Adjust Monitor Height
In addition to turning down the brightness, you can adjust the height of your monitor to protect against eye strain. For optimal viewing, you should position your monitor so that the top of it parallel to your eyes. When looking directly in front of you, in other words, you should see the top of your monitor. Research has shown that maintaining a similar height between the top of your computer monitor and your eyes lowers the risk of eye strain.
Look Away Every 20 Minutes
Staring at a computer monitor for multiple consecutive hours is a surefire way to strain your eyes. You can still use a computer for an extended period; you just need to give your eyes a break by looking away. A good rule of thumb is to look away from your computer monitor at least once every 20 minutes. Some office workers use the 20-20-20 rule, meaning they look at an object that's roughly 20 feet away for 20 seconds every 20 minutes.
It may sound unusual, but many office workers forget to blink when using a computer. Blinking is important because it lubricates your eyes and, therefore, protects them from dryness. If you rarely blink, your eyes will become dry, which could lead to eye strain. Blinking often will lower the risk of eye strain by ensuring that your eyes are properly lubricated.
Maintain Correct Posture
Don't forget to maintain correct posture when using a computer. If you slump over, you may be forced to view the monitor at an awkward and unnatural angle. Over time, this awkward viewing angle can strain your eyes.
