How to Enable Night Light on Windows 11

Windows 11 users can easily activate the night light mode to reduce blue light emission, which can negatively affect eyesight and sleep quality. In this article, we’ll go over how to enable and customize night light on Windows 11.

What is Night Light and Why is it Useful?

Night light is a feature that reduces the amount of blue light emitted by the screen. Blue light is considered particularly harsh on the eyes, especially in the evening, as it can disrupt circadian rhythms and interfere with natural sleep. Night light adjusts the screen to a warmer, more yellowish tone, which is gentler on the eyes and more comfortable for nighttime viewing.

How to Enable Night Light on Windows 11

  1. Open Windows Settings. Click on the Start menu or use the Win + I shortcut to open the settings quickly.
  2. Go to the "System" section. In the settings window, select “System” from the left-hand menu.
  3. Select “Display.” Under “System,” find and click on “Display” to open additional display settings.
  4. Turn on “Night Light.” Find the “Night Light” switch and toggle it to “On.” Your screen will immediately change to a warmer tone.

How to Adjust the Intensity and Schedule for Night Light

Windows 11 allows you to not only turn on night light but also customize it to suit your needs.

  1. Open Night Light settings. In the “Display” section, click on “Night Light settings” to access more options.
  2. Adjust the light intensity. Move the slider left or right to set the level of screen warmth. The warmer the screen, the less blue light will be emitted.
  3. Set a schedule for Night Light. You can specify the times for night light to turn on and off automatically. For example, you can choose “sunset to sunrise” mode, which is especially useful during the winter months.

Additional Tips for Comfortable Nighttime Computer Use

  • Reduce screen brightness in the evening.
  • Use dark mode in apps and system settings to ease eye strain.
  • Follow the 20-20-20 rule for eye comfort: every 20 minutes, look at an object 20 feet away for at least 20 seconds.

Now you know how to enable and customize night light on Windows 11. Use this feature to reduce eye strain and improve sleep quality, especially if you frequently work on your computer in the evening.
