New iOS 17 Feature Warns You When Holding iPhone Too Close to Your Face

New iOS 17 feature Screen Distance warns you when holding your iPhone too close to your face, which can cause eye strain.

Screen Distance aims to reduce eyestrain and lower risk of nearsightedness by blocking your screen when held too close.

To turn on Screen Distance, open Settings > Screen Time > Screen Distance. It turns on automatically after intro screens.

When holding phone too close for too long, you'll get a "iPhone May Be Too Close" message blocking your screen.

To turn off Screen Distance if you find it annoying, open Settings > Screen Time > Screen Distance and toggle it off.
