How to Enable Night Light on Windows to Reduce Eye Strain

If you spend long hours in front of your computer screen at night, the blue light can cause significant eye strain and make it harder to fall asleep. This guide will show you the safest and most effective way to solve this problem using built-in Windows 10 and 11 tools. This method works for both beginners and advanced users.

WHY THIS MATTERS

You may need to perform this action when:

• You experience dry eyes or headaches after late-night computer use.

• You want to improve your sleep quality by reducing blue light exposure before bed.

• You prefer a warmer, more comfortable screen tone in dark rooms.

WHAT YOU WILL NEED

• A computer running Windows 10 or Windows 11

• 1 minute of time

STEP 1 — Open Display Settings

Actions: Right-click anywhere on your empty desktop background and select Display settings from the context menu.

STEP 2 — Toggle Night Light On

Actions: Under the "Brightness & color" section, look for the Night light option. Move the toggle switch to the On position.

STEP 3 — Adjust the Strength

Actions: Click on the small arrow (or the words "Night light") next to the toggle to open advanced settings. Here, you can adjust the Strength slider to make the warm color more or less intense.

ALTERNATIVE METHOD

If you want to turn the feature on or off quickly without opening settings, try this:

1. Press the Windows key + A on your keyboard to open the Quick Settings panel on your taskbar.

2. Click the Night light icon to toggle it instantly.

COMMON MISTAKES

• Setting the strength too high — A completely orange screen can distort colors, making photo editing or watching movies difficult. Find a comfortable middle ground on the slider.

PRO TIP

You can set Night Light to turn on and off automatically! In the advanced settings (Step 3), click Schedule night light and choose "Sunset to sunrise" or set your own custom hours.

RESULT

After completing all steps, you will achieve: A warmer, eye-friendly screen display that automatically filters out harsh blue light in dark environments.
