The iOS 17 beta 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.
