Turning off the blue light on Windows 11 can make a big difference when your eyes feel strained after a long day. Whether you’re burning the midnight oil or binge-watching your favourite shows, it’s just a quick flick to make the screen emit less harsh blue light and be easier on your eyes. The steps are straightforward, but sometimes finding that toggle isn’t as obvious as it looks — Windows has a habit of hiding these features where you least expect them.
Step-by-Step Tutorial to Turn Off Blue Light on Windows 11
In this guide, you’ll learn how to disable the blue light (or Night light) on Windows 11. Usually, it’s just a matter of flicking a switch and seeing your screen return to normal, but occasionally it’s tucked away a bit, especially if settings have been changed or updated.
Step 1: Open Settings
Click the Start button, then select Settings. You can also hit Windows + I for a quicker route. Look for the gear icon — pretty easy to spot.
Step 2: Head to System
Once in Settings, choose System. It’s usually the first option, and if you’re familiar with Windows, it covers all the display, sound, and power settings. Sometimes, if you do a quick search (using the magnifying glass), just type “Display” and jump straight there, but for clarity, open System first.
Step 3: Click on Display
This is where all the screen-related tweaks live. Tap on Display. Inside, you’ll see options like brightness, resolution, and colour profiles. That’s where you’ll find the blue light controls.
Step 4: Locate the Night Light Setting
Scroll down a bit — the Night light toggle is under the Brightness & colour section. Sometimes it’s easy to miss because it’s not always turned on by default. On some setups, the toggle looks like a switch in either the “On” or “Off” position. If it’s greyed out, you might need to turn it on first (more on that in a sec). This is where you control blue light emission.
Step 5: Turn Off Night Light
Simply switch the toggle to Off. That’s all there is to it. Turning it off disables the warmer tone and makes your display behave normally. Sometimes Windows asks you to restart or sign out for the changes to fully take effect, but most of the time, it’s instant. On some machines, that toggle can be a bit stubborn — if so, a quick reboot should sort it out.
And if the toggle’s missing or won’t switch, check if you’ve got any third-party apps or hardware settings (like monitor calibration or blue light filters from your graphics card software). Windows isn’t the only boss here.
If you want more control, you can click Night light settings underneath the toggle. Here, you can schedule times, adjust the warmth slider, or turn it on/off based on time. It looks like this:
Settings > System > Display > Night light > Schedule options / Warmth sliderThis feature is handy if you want it to turn back on automatically at sunset, for example. Setting up a schedule saves you from having to flip it manually every time — a bit odd how Windows makes you dig for these things sometimes, eh?
Tips for Turning Off Blue Light on Windows 11
- Set a Schedule: If you prefer it on at night but not during the day, just toggle “Schedule night light” and pick your hours. Fair dinkum.
- Adjust Brightness: Sometimes, even with blue light off, your screen still feels a bit too bright or harsh. Dial down the brightness using the slider or Fn + Brightness keys.
- Try Third-Party Apps: Want more options? Apps like Winhance or f.lux give you extra control, scheduled tinting, and profiles. Of course, Windows can’t make it easy sometimes.
- Check Hardware Settings: Some monitors come with their own blue light filters. Double-check your monitor’s on-screen menu for settings like “Low Blue Light” or similar. They can sometimes override Windows settings.
Frequently Asked Questions
What is blue light?
Blue light is a high-energy visible light in the spectrum, which can cause eye fatigue or mess with your sleep if you’re exposed late at night. Basically, it’s why your eyes sometimes hurt after a long binge on the screen.
Why does Windows 11 have a night light feature?
It’s designed to cut down on blue light, easing your eyes and hopefully helping you nod off if you’re working late. It’s a built-in way to reduce eye strain without needing extra gadgets.
Can I schedule when the night light turns on and off?
Yep. Under Settings > System > Display > Night light, you can set custom hours. Sometimes it works like a charm; other times, a quick restart might do the trick if it’s acting up.
Does turning off blue light save battery life?
Not really. This is a display setting, so it doesn’t make much difference to power drain—unless you’re running apps that boost brightness or warmth constantly.
Are there other tricks to cut down blue light?
Absolutely. Besides Windows’ native options, screen filters or specialised software like Winhance or f.lux can give you extra features, scheduled tinting, and custom profiles.
Summary
- Head into Settings > System > Display.
- Find the Night light toggle.

Hope this helps someone save a few hours or at least makes late-night scrolling a bit kinder on your eyes. Good luck once again!
