Scrolling through blogs, playing on apps and replying to emails in bed is a habit shared by a lot of people. For many of us, it’s the only sweet bit of downtime we get all day. But exposure to the blue light emitted by devices, especially before bed, can have a major impact on sleep quality. That’s where the Blue light reduction feature comes in.
This hack is recommended for use during those hours before you want to sleep. Dimming down the blue light (you can even make your device do this automatically at sunset, clever huh?) can alleviate eye strain and reduce the negative impact of gadget exposure before sleep.
With your device unlocked, swipe down from the top of the screen to reveal the Quick Settings panel.

Tap Blue light filter to immediately activate.
