Blue light on Windows 10

Creators Update – Windows 10 now includes a feature called “Blue light” to help you reduce eye strain and improves quality sleep when you’re in front of a computer screen.

Blue 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, 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 Blue light on Windows 10.
