How to Turn On and Configure Windows Night Light

With the rollout of the Creator's Update for Windows 10 in April 2017, Microsoft introduced a Night Light feature. When enabled, the Night Light feature limits exposure to blue light, which can result in eye fatigue and lower-quality sleep. The Night Light feature reduces the exposure to blue light by shifting to warmer colors, such as red and yellow, which results in less stress on the eyes, and potentially a more restful night for users who are up late working on their computer. This article walks you through how to enable and adjust the Night Light feature in Windows.

1. Press the "Windows" and "A" keys at the same time. The Action Center appears along the right side of your screen. The Action Center will contain system alerts and application alerts for any applications you've allowed to pass and post alerts.

2. Select "Expand" at the bottom of the Action Center window. Expand appears on the right side of the window, directly above the All Settings icon. The icon tray along the bottom of the screen flys up, exposing more rows of icons. Other shortcut icons that appear will include VPN, Airplane Mode, Quiet Hours, Brightness, and more. Night Light appears along the bottom row, at the very end of the list of icons.

3. Click "Night Light." You'll notice that your screen takes on more of a yellow hue. Additionally, you'll notice that the Night Light icon becomes shaded darker. You can navigate back to this screen at any time and click the Night Light icon again to turn the feature off.

1. Press the "Windows" and "A" buttons at the same time to open the Action Center.
