iOS 17 comes with a feature designed to enforce one of the rules your parents likely set out all those years ago — by making sure you’re not sitting too close to the screen. Screen Distance is an opt-in feature designed to alleviate eye strain, and help reduce the risk of near-sightedness in children that spend a little too much time with their screens.

Because it’s far too easy to accidentally slip closer to that screen when you’re engrossed in something, so Apple is using iOS 17 to do something about it. Screen Distance uses Face ID to detect when you’re sitting too close to the screen for an extended period, stopping you from continuing until you back off a bit.

Screen Distance is an opt-in feature, though. So if you’re worried about how screens might impact the eyes of you or your family, you’ll have to go into the settings to get everything set up. Here’s how to set up Screen Distance in iOS 17.

If you’re still running iOS 16, be sure to read our guide on how to download and install iOS 17, Screen Distance is exclusive to the latest version for Apple’s operating system.


You can check which software your device is running by heading to Settings > General > About > iOS version 

2. Go into the Settings app and select Screen Time

From your device’s home screen, or App Library, find the Settings app and tap the Screen Time option. You’ll find it in the second block of options, below Focus but above General.

3. Tap Screen Distance

Once in the Screen Time menu, tap the Screen Distance option. It’s the second one down, directly below App & Website Activity

4. Tap Continue on the following two information screens

The next two screens will explain what Screen Distance is, how it’ll be of benefit to users, and what to do if the Screen Shield warning flashes up. 


The feature itself is designed to reduce eye strain and the increased risks of myopia associated with up-close screen usage. And should a warning flash up, you’ll need to move the screen at least 12 inches (or 30cm) away from your face before you’re given the option to continue.

5. Ensure Screen Distance is toggled on

The final screen has a single toggle, which lets you switch Screen Distance on and off at your leisure. It should be switched on once you get through the previous confirmation screens, but just be sure that the switch is green if you want Screen Distance turned on.

6. Test Screen Distance for yourself

From here Screen Distance will work in the background, only ever activating if Face ID detects that you’re sitting too close to the screen for an extended period. It doesn’t happen instantly, though, and in our brief testing we found that it takes around 5 minutes before the Screen Shield appears on screen — at which point my eyes were already hurting.
