There may be some issues with how much blue light your desktop screen emits and how it may cause issues with your eyes down the road.  The blue light your computer monitor emits can also contributes to sleeplessness and eye strain after dark.

Ubuntu comes with a feature called Night Light that may help you resolve some of the eye issues you may be experiencing at night in front of your screen. Night Light also changes the colors displayed on your screen into warmer versions of themselves.

This brief tutorial shows students and new users how to enable Night Light with using Ubuntu desktops.To get started with enabling Ubuntu Night Light feature, follow the steps below:

  • Open the Activities overview and start typing Settings.
  • Click on Settings.
  • Click Devices in the sidebar.

  • Click Night Light to open the settings.
  • Set the Night Light switch to ON. The screen color will follow the sunset and sunrise times for your location. Click the Manual button to set the times to a custom schedule.
