How to Turn On Night Light in Windows

Tap through each step to warm up your screen for late-night use.

  1. Go to Settings, System, Display

    Open the Settings app and go to "Display" under the "System" menu.

  2. Turn on "Night light"

    In the "Brightness & color" section, switch on the Night light toggle.

  3. Adjust the color temperature (strength)

    Move the slider to control how warm (orange-tinted) the screen becomes.

  4. Set an automatic schedule

    Turning on "Schedule" lets Night light switch on automatically from sunset to sunrise, or during whatever hours you choose.

  5. Why it is worth using

    Staring at a screen for long stretches at night exposes your eyes to blue light, which can add to eye strain and affect sleep. Shifting the screen to warmer tones with Night light makes late-night use noticeably easier on the eyes.

When staring at a screen at night leaves your eyes tired

Screens emit a significant amount of blue light, and extended exposure at night is associated with more eye strain and can interfere with winding down for sleep. Night light does not eliminate this on its own, but shifting the display toward warmer, orange-tinted tones in the evening makes long sessions noticeably more comfortable and is a small change worth making a habit.

One thing to remember about color accuracy

Because Night light intentionally skews colors warmer, it is not meant to stay on during work that depends on accurate colors -- photo editing, color grading, or design work where true whites and blues matter. It is worth toggling off for that kind of task and back on afterward, rather than leaving it on all the time regardless of what you are working on.

Frequently Asked Questions

Does Night light get in the way of photo editing?

Yes -- colors look different from how they actually are, so it is best to turn it off temporarily while editing photos or doing color-sensitive work.

Can I just turn it on once without setting up a schedule?

Yes -- leave "Schedule" off and just flip the toggle on. It stays on from that moment with no schedule until you switch it off yourself.
