Commonly branded as ‘night mode,’ a blue light filter does exactly what the name says—it filters the blue light of your phone by turning your screen to an amber-like color. By filtering the blue light of your smartphone, it can make it easier to look at your screen or read in the dark and can even help you fall asleep more easily. Many phones nowadays come with this basic feature built-in; however, users of older devices may have to resort to a third-party app such as Twilight to get this functionality.
Let us know if you use night mode for your phone, and feel free to share your thoughts in the comment section below.
