So that your eyes can rest for a while
Windows 10 Night Light Not Working
Constant exposure to blue light from electronic devices can cause visual problems and disrupt your sleep patterns. On Windows 10, the Night Light feature prevents digital eye strain and improves sleep quality by reducing blue light emissions from your computer display.
Despite its benefits, there are times when the feature doesn’t work properly. If you’re on this page because Windows 10 Night Light is not working on your Windows 10 computer, try the possible solutions listed below.
If you choose the Windows preset "Sunset to Sunrise" schedule, Night Light will turn on at 7:30 PM and turn off at 6:30 AM every day. If you choose to set your own custom hours, be sure to enter the correct time in the boxes provided.
