Eye strain is one of the most common complaints among people who spend extended time on screens. Bright white interfaces like the default look of most websites and apps push out high levels of blue light, which can trigger headaches, make it harder to sleep, and cause genuine discomfort during evening scrolling sessions. That is precisely why dark mode has become one of the most requested features across every major digital platform over the past few years, and why so many users are actively looking for how to enable it on the apps they use most.
Facebook’s dark mode replaces the platform’s signature bright white background with a near-black interface, shifting text to white or light grey and softening the overall color scheme into something significantly easier on the eyes. If you are spending time on Facebook at night or in dimly lit spaces, learning how to get dark mode on Facebook is one of the simplest quality-of-life changes you can make.

In this guide, we will cover every method for enabling Facebook’s dark theme, including step-by-step instructions for desktop, Android, and iPhone, and how to activate dark mode on Facebook Messenger separately.
What is Facebook dark mode?
Facebook Dark Mode is a display setting on Facebook that changes the app’s background from bright white to a darker theme, usually black or deep grey. This makes the interface easier on the eyes, especially at night or in low-light environments.
Instead of the usual bright layout, Dark Mode reduces screen glare and can help limit eye strain during long browsing sessions. It also gives the app a more modern, sleek appearance that many users prefer.
Why bother with Facebook dark mode?
Facebook dark mode is a hidden but useful feature that improves comfort, saves energy, and changes the overall look of your Facebook experience. That said, its benefit goes beyond aesthetics alone and here are some:
1. Reduced eye strain
Prolonged exposure to a bright white screen in a dark environment creates a high contrast that forces your eyes to work harder. Dark mode reduces that contrast and can meaningfully reduce discomfort during late-night browsing sessions.
2. Better sleep
Screens emit blue light, which suppresses melatonin production and signals your brain to stay alert. Research published in the journal PNAS found that exposure to blue-light-emitting screens in the hours before bed reduces sleep quality. Switching to dark mode reduces your blue light exposure during evening phone use.
3. Battery savings
This is a real, measurable benefit for mobile users. Google confirmed that black pixels on OLED displays consume significantly less power than white ones at full brightness. Therefore, switching to a dark interface can reduce display power usage by up to 63%. If your phone has an OLED screen which includes most modern iPhones and premium Android devices, Facebook dark mode will measurably extend battery life.
4. Visual comfort and readability
Many users simply find white text on a dark background easier to read for extended periods. It is also less disruptive in shared environments like cinemas, bedrooms, or public transport at night.
How to enable Facebook dark mode on desktop
Facebook’s desktop dark mode setting is straightforward to find, though it sits inside a menu. To get the dark mode on desktop, follow these steps:
- Open your web browser and go to facebook.com.
- Look for the profile icon and click on the downward-pointing arrow icon (▾) in the top right corner of the navigation bar. It sits to the right of the Messenger icon. Click it to open the account menu.
- In the dropdown that appears, click “Display & Accessibility.”
- Click on Accessibility to proceed to the next step.
- Under Accessibility, click on ‘Display’ option.
- On the next page, you will see the ‘Dark mode’ option with is automatically turned off.
- Clicking on the ‘off’ button displays the available options which include: On, Off, and Automatic.
- Select “On” to immediately switch to Facebook’s dark interface.
The “Automatic” option when selected, Facebook will follow your computer’s system-wide dark mode setting. If your operating system Windows, macOS, or Linux is set to dark mode, Facebook will switch to dark automatically. If your OS switches to light mode, Facebook will follow. This is the most convenient option if you already use system-level dark mode.
This desktop dark mode setting only applies to the full desktop version at facebook.com. It does not apply to the mobile website (m.facebook.com), which does not have its own built-in dark mode toggle.
How to turn on Facebook dark mode on Android
Just like the desktop version, the Android app has a straightforward dark mode toggle, but it is one layer deeper than most users expect.
- Open the Facebook app on your Android device.
- Tap the three horizontal lines (≡) also called the hamburger menu at the top right corner of the app. This opens the main menu.
- Scroll down to “Settings & Privacy” and tap it to expand the submenu.
- Tap “Dark Mode” from the submenu options.
- You will see three options: On, Off, and Use System Settings.
- Select “On” to activate Facebook dark mode directly, or choose “Use System Settings” to sync Facebook’s appearance with your Android device’s display settings.
If you choose “Use System Settings,” Facebook will automatically switch to dark mode whenever your Android device’s dark theme is enabled.
How to get dark mode on Facebook app on iPhone
The iOS path is slightly different from Android. Although different, it still arrives at the same
- Open the Facebook app on your iPhone.
- Tap the three horizontal lines (☰) in the bottom right corner of the screen (in the navigation bar) to open the menu options.
- Scroll down and tap “Settings & Privacy.”
- Tap “Dark Mode.”
- Select either “On” to activate dark mode immediately, or “System” to follow your iPhone’s display settings automatically.
The “System” option on iPhone works through iOS’s Appearance setting. You can configure your iPhone to switch to dark mode automatically at sunset by going to Settings, clicking on Display & Brightness and tap Automatic and toggling it on.
How to enable dark mode on Facebook Messenger
Facebook Messenger operates as a separate app with its own dark mode setting, independent of the main Facebook app. Enabling dark mode on Facebook does not automatically change Messenger’s appearance.
On iPhone:
- Open Messenger

- Toggle the switch to enable it, or select “System” to sync with iOS appearance settings
On Android:

If you use the standalone messenger.com website, you will need to enable dark mode separately through the same account menu.
Use your device’s system dark mode as a Shortcut
The quickest way to switch Facebook to dark mode without opening any app settings is to enable system-wide dark mode on your device. When the Facebook app is set to “System” (iOS) or “Use System Settings” (Android), it automatically adopts your device’s display mode.
On iPhone:
- Open Settings
- Tap Display & Brightness
- Select Dark to activate it immediately
- Or choose Automatic to switch between light and dark at sunset
On Android:
- Open Settings
- Tap Display
- Select Dark Theme
- Toggle it On
- On newer versions (Android 12+), you can also say: “Hey Google, turn on dark mode”
On Windows (browser)
- Open Settings on your computer
- Go to Personalization
- Click Colors
- Select Dark
- If Facebook’s automatic setting is enabled, it will switch instantly in your browser
On macOS:
- Open System Settings
- Click Appearance
- Select Dark to activate it
- Or choose Auto to switch based on time of day
Why can’t I find Facebook Dark Mode?
Sometimes, you might not get to see the dark mode option on your Facebook. This can be due to multiple reasons such as a new app update, or just app data error. Regardless of what might be the case, here are the most effective fixes:
1. Update the Facebook app
An outdated app version is the most frequent cause of missing dark mode settings. Open the Google Play Store (Android) or App Store (iPhone), search for Facebook, and install any available updates. Dark mode settings have disappeared and reappeared following specific app versions in the past.
2. Use your device’s system dark mode
If the dark mode option is missing from within the Facebook app, use your device’s system-wide dark mode as a workaround. Enable dark mode at the device level through Settings, then the Facebook app will generally follow even without the in-app toggle being accessible.
3. Clear the app’s cache (Android)
On Android, a corrupted app cache can cause settings and display options to disappear. Go to Settings, Apps, then click on Facebook, followed by Storage before tapping on Clear Cache. This does not delete your account or data but it only removes temporary files. Reopen Facebook and check if dark mode has returned.
4. Force stop and restart the app
On iPhone, double-tap the home button or swipe up on newer models and swipe the Facebook app off the screen to fully close it. On Android, go to Settings followed by Apps, Facebook and then Force Stop. Relaunch the app and navigate back to dark mode settings.
5. Uninstall and reinstall the Facebook app
If all else fails, uninstalling and reinstalling the Facebook app resolves most persistent settings issues. Your account data is stored on Facebook’s servers, not on your device, so a fresh install will not affect your posts, messages, or friends.
In the end
Facebook dark mode is available and easy to activate across multiple devices and the benefits go well beyond appearances. With dark mode activated on your Facebook account, you can worry less about eye strain, sleep quality, or battery life, and the few seconds it takes to enable it are worth it.
