To avoid ruining your vision due to constant screen viewing, it is recommended a simple "20-20-20" rule. In translation: every 20 minutes, you should take a look from the screen for 20 seconds and look at a point that is 20 feet (6 meters) away from you, while blinking. Although doctors warn us that a short pause should be made every hour, we often simply forget about this advice. Therefore, at the end of the working day, more and more people have the feeling that their eyes are tired and dry, and this is especially pronounced in people wearing glasses or lenses.

It doesn't matter if we want to admit it or not, but during the day we spend too much time in front of different screens. From television, through tablets and smartphones to the monitor. If you have an opportunity to invest, you can purchase some of the newest monitors that have reduced flicker (backlight), and some other improvements like those that can be found in Rackmount Monitor, that will keep your eyes be protected. If not, there are some tricks that can help you:

The position of the monitor

First of all, check the position of the screen in relation to your body. The screen should be between 20 and 28 inches (50 and 70 centimeters) from your eyes, and its top should be in level with your eyes. If you can not adjust the screen height, try placing a few solid books below to raise it. Or simply lift or lower your chair. In any case, during work, you should look down at an angle of 15 to 20 degrees.

Check the letter size

In addition to the position of the screen, the size of the letters and their color is also important. The text should be three times larger than the minimum size you can read at a distance of at least 20 inches (50 centimeters). Make a test in one of the programs in which you can change the font size.

In addition, a large role is played by the background color. The most striking is the text that is contrasting with the background. For example, black text on a white background or a white text on a black background. Avoid reducing the contrast on the monitor, as this will only fatigue the eyes.

Reduce the lighting

Depending on the operating environment, adjust the lighting on your screen. Smartphones and tablets have a sensor that automatically adjusts the brightness of the screen to the environment. As the daylight brightness of your room changes, you will need to adjust the screen brightness more often.

For best settings, use any page that has a lot of white colors. If the white "jumps" from the screen, lighting should be reduced. If you are working in an area where there are many reflective surfaces, such as windows or glass bulkheads, consider purchasing a filter to prevent the screen from reflecting.
