We’ve all read the reports: Blue light can play a role in sleep issues. It’s also been mentioned as a factor in skin damage, too. Fortunately, not only can you enable a blue-light filter on your smartphone, you can do so in Windows 10, too.

In fact, the process is incredibly easy—setup takes just a few minutes. Here’s how to do it.

Step 1

Jumping into the Night Light settings via Windows 10’s robust search feature is easiest, but if you go the manual route, here’s where to find the link to that setting.

Click on the Start menu (or tap the Windows key on your keyboard). Then type in “Night Light” to bring up a direct link to that setting.

Alternatively, you can go to Start > Settings > Display, then click on Night light settings under Color (see image above). If you take this route, you can turn Night Light on and off via a toggle on the Display settings page.

Click the Turn on now button to immediately activate blue-light filtering. Move the strength slider to increase or decrease how much blue light Windows 10 will eliminate.

Never used a blue-light filter before? Before turning on Night Light, you can first play with the strength slider for a preview of what your screen will look like at various intensities—it’ll essentially let you try before you buy.

You can also instead click the gray toggle for Schedule night light to restrict the blue-light filtering to specific hours. Customize a time span for when the blue-light filtering is on, and you’re all set to go. Windows can also base the schedule on your location’s periods of actual sunset. You’ll just need to turn on Location Services for that to work—if your system has that setting off, a link to Location settings will automatically appear.

That’s it. You’re done!
