Night light is a feature on Windows 10 that helps reduce eye strain and improve sleep quality at night — Here's how to set it up.

Windows 10 Night Light

Windows 10 now includes “Night light,” a new feature to help you reduce eye strain and improves quality sleep when you’re in front of a computer screen.

Night light on Windows 10 works by reducing the amount of blue light your display emits, which is the kind of light you see during the day. At night, if your eyes continue to receive this kind of light increases the chances of your eyes strain and disrupting your sleep. On the Windows 10 Creators Update and later versions, the operating system can show warmer colors to make it easier on the eyes and help you fall asleep faster at night.

In this guide, you’ll learn the steps to enable and configure Night light on Windows 10.
