Screens emit blue light that apparently makes it harder to sleep at night if you stare at your display for a long time. The new night light feature in Windows 10 displays warmer colors to remedy this.
This handy little feature borrows the functionality of the beloved f.lux app.
It essentially adjusts the color temperature of your screen to something that is lighter on the eyes, and perfect for after-dark computing sessions. This not only causes less strain on your eyes, but makes it easier to fall asleep when you are done.
Learn how to turn night light on or off in Windows 10 by following these simple steps.
1. Open the Settings app, then head to System and then Display.
2. You can toggle the switch to turn Night light on.
3. The Night light settings link below takes you to a dedicated panel for the feature where you can adjust the settings and fine tune its behavior, including color temperature and timing.
