Tap your device to see how to set it up.

iPhone - Night Shift

Go to Settings > Display & Brightness > Night Shift and set a schedule so the screen automatically shifts to warmer colors at the times you choose.

Android - Eye Comfort Shield / Night Light

Go to Settings > Display > Eye comfort shield (or Night Light) and turn it on to reduce blue light on your screen.

Windows - Night Light

Go to Settings > System > Display > Night light, turn it on, and set an automatic schedule.

Mac - Night Shift

In System Settings > Displays > Night Shift, you can set a schedule and adjust the color temperature.

Does it actually help you sleep?

Some research suggests reducing blue light can support better sleep, but many experts argue that cutting screen time before bed matters more than color temperature alone.

Make your screen easier on the eyes before bed

Warming up your screen's colors in the evening can help ease eye strain. Most devices let you schedule this to switch on and off automatically, so you don't have to remember to toggle it every night.

Curious about dark mode too?

Dark mode and night mode solve different problems -- one changes background brightness, the other changes color temperature -- so it's worth understanding how each works if you're trying to make screen time easier on your eyes.

Frequently Asked Questions

Does turning on night mode change how photos look too?

Night mode adjusts the color temperature of your entire screen, so if you need accurate color for photo editing or design work, it's best to turn it off temporarily.

Are dark mode and night mode the same feature?

No -- dark mode changes bright backgrounds to dark ones, while night mode (or Night Shift/Night Light) shifts the screen's color temperature to reduce blue light. They're independent features that can be used together.
