How To Configure Night Light In Ubuntu

If you work on a computer for any length of time, you’re probably familiar with eye strain. It’s that tired, achy feeling you get after viewing the computer screen for too long. And if you’re like many people, you might not even realize that there are things you can do to reduce eye strain when working on a computer.

One of the easiest things you can do is to adjust your computer’s display. The color temperature of your display can have a big impact on your eyes. If it is too high, it can cause eye strain. But if it’s too low, it can make your eyes feel dry and irritated.

Ubuntu has the Night Light setting for this. Here is how to use it:

Right-click anywhere on the desktop and click on Display Settings.
