Night Light is a feature introduced in the Windows 10 Creators Update that helps reduce blue light emissions by adjusting your screen to warmer colors, making it easier on your eyes and improving sleep quality. Here’s how you can turn Night Light on or off in Windows 10.
Enable or Disable Night Light in Windows 10
- Press the Windows + I keyboard shortcut to open the Settings app, and then click on the System icon.
- Select the Display tab on the left side. You can then toggle the “Night light” button to On to enable it, or Off to disable it.
- If you enable the Night Light feature, you can configure it further by clicking the “Night light settings” link under the toggle.
There, you can adjust the color temperature by dragging the slider and set Night Light to activate when the sun sets, automatically disabling it at sunrise. Once configured, you can click the “Turn on now” button to immediately enable the Night Light feature.
