The brightness of your screen can have an effect on your comfort; too bright and the glare can cause eye fatigue and strain, and having the screen too dull can make the text harder to read, also causing strain.
Nearly all monitors allow you to adjust the screen brightness and as a general rule, your screen shouldn’t be any brighter or duller than the area behind it, so the monitor blends in with its surrounding. Some professionals even recommend that you adjust the screen brightness during the day if the area around your computer is lit by natural light which changes as the day progresses.
If you are using a computer with a separate monitor, the screen brightness is usually controlled by a button on the front of the monitor. If your monitor has a special button for adjusting the brightness it will usually have a sun symbol next to it, or you may need to press a “Menu” button to access this setting.
The brightness for laptop screens is usually controlled by pressing the “FN” key together with one of the function keys on the top row of keys. Which function key varies from laptop to laptop but there are usually two keys with a sun symbol; one for increasing the brightness and another for decreasing it.
