Reducing eye strain during nighttime use or in low-light environments is crucial for maintaining good eye health and ensuring better sleep quality. The Night Light feature in Ubuntu helps by minimizing the blue light emitted by the screen, which is known to disrupt sleep patterns and affect the body's natural circadian rhythm. Enabling Night Light results in a warmer display, making it easier on the eyes during evening and night hours.

Ubuntu includes the Night Light feature in its recent versions, making it easily accessible. This feature can be activated through the Settings application, specifically within the Display section. Users can configure Night Light to adjust automatically based on sunset and sunrise timings or to set custom schedules that fit their preferences, allowing seamless integration into daily routines without constant manual adjustments.

Steps to enable night light feature in Ubuntu:

  1. Open Settings application from the application menu or dock.
  2. Navigate to the Display section in the left sidebar.
  3. Click on the Night Light tab.
  4. Toggle the switch to enable Night Light.
  5. Adjust the color temperature according to your preference using the slider.
  6. Choose the schedule you want for the night light feature:
  7. Select Sunset to Sunrise for automatic adjustments.
  8. Select Manual to set a custom start and end time for the night light.
  9. Close the Settings application once you've configured your preferences. Your night light settings will now be applied based on the schedule or times you've chosen.
