How to Enable Night Light in Windows 11

Windows 11 includes a built-in feature called Night Light that reduces the amount of blue light emitted by your screen. Blue light can cause eye fatigue and disrupt your natural sleep patterns, especially when using your computer late in the evening. This guide explains how to quickly turn on Night Light, adjust its color warmth, and configure an automatic schedule so your display automatically transitions to warmer tones at night.

Method 1: Turn on Night Light via Quick Settings

The fastest way to toggle Night Light on or off is through the Windows 11 Quick Settings menu:

1. Click the Quick Settings area in the bottom-right corner of your taskbar (the area containing the Wi-Fi, volume, and battery icons), or press the keyboard shortcut Windows Key + A.
2. Locate the Night light tile.
3. Click the tile once to turn the feature on. The tile will turn blue to indicate it is active, and your screen will immediately shift to a warmer hue.

Method 2: Enable and Customize Night Light in Settings

To adjust the intensity of the warm color or to set up an automated schedule, use the main Settings menu:

1. Open Settings by pressing Windows Key + I or clicking the Start menu and selecting the gear icon.
2. Navigate to System on the left sidebar, then click on Display in the right pane.
3. Toggle the switch next to Night light to the On position.
4. Click the arrow > next to the Night light toggle to open advanced configuration options.

How to Adjust Strength and Schedules

Inside the Night light settings page, you can tailor the feature to your visual preferences:

• Adjust Strength: Move the Strength slider left or right. A higher percentage increases the warmth (amber tint) and blocks more blue light, while a lower percentage keeps the screen closer to its normal color profile.
• Automate by Sunset/Sunrise: Turn on the Schedule night light toggle and select Sunset to sunrise. Windows will automatically determine your local sunrise and sunset times (Location services must be enabled for this to work accurately).
• Set Custom Hours: If you prefer specific times, choose Set hours under the schedule section. Specify your preferred Turn on and Turn off times to match your daily workflow.
