Prolonged use of mobile phone puts extra strain on the eyes. But many people use Facebook for a long time at night, resulting in eye damage. You can use the Dark Mode feature on Facebook to solve the problem. Facebook’s Dark Mode feature can be easily launched on mobile phones running Android and iOS operating systems.
Launch the Facebook app on a mobile phone running the Android operating system and click on the menu (three horizontal lines) in the upper right. Now you have to select the Settings & Privacy option in the gear icon. Select the Dark Mode menu from the Preferences section at the bottom of the page. When the DarkMod page opens, selecting the On option here will turn on Facebook’s DarkMod. If you want to stop, you have to select the Off option using the same method.
Launch the Facebook app on the iPhone running the iOS operating system and click on the menu below (three horizontal lines). Now select the Settings & Privacy option in the gear icon and select the Dark Mode menu in the Preferences section of the page. After launching the Dark Mode page, pressing On will turn on the Dark Mode of Facebook. Selecting Off will close.
