Tips/Enabling the blue light filter on KDE Plasma

Introduction

Eye strain and insomnia are real problems. With all the screens we’re exposed to on a daily basis, it’s hard for our bodies to adapt to all that light. Sometimes, we need to keep using our electronic devices late at night, and the blue light from our device’s screens can impact both our eyes and our sleep.

Fortunately, it’s possible to mitigate the harmful effects of blue light by enabling a blue light filter, and KDE Plasma offers one by default. In this article, we’ll explore how you can enable it.

On KDE Plasma, the blue light filter is called Night Color. We’ll be referring to it as such from now on.

• Search for Night Color on the Application Launcher or open up System Settings and navigate to Display and Monitor > Night Color as shown below:

This is the Night Color settings window
