iOS 17 introduces a new feature called Screen Distance, designed to reduce eyestrain by alerting users when their iPhone or iPad is too close to their face. This feature, which could also lower the risk of myopia, is a part of Apple's latest efforts to enhance user health. Users can easily enable or disable Screen Distance through the Screen Time settings on their devices.

The primary function of the Screen Distance feature introduced in iOS 17 is to help reduce eyestrain and the risk of developing myopia (nearsightedness) by alerting users when they are holding their iPhone or iPad too close to their face1. This feature operates by using the device's TrueDepth camera to detect the proximity of the screen to the user's face. If the device is held too close for a prolonged period, Screen Distance issues a warning to encourage the user to increase the distance, thus promoting healthier viewing habits2. This is especially aimed at children and individuals who spend extended periods using devices, helping to mitigate potential eye health issues from close-up screen exposure.

To activate the Screen Distance feature on an iPhone, follow these steps:
After these initial steps, you will encounter two informational screens explaining the Screen Distance feature. Tap Continue on both of these screens to proceed. Once you complete these steps, the Screen Distance feature will be automatically activated1. This setup is only required the first time you enable Screen Distance1. After activation, the feature will start functioning immediately to help reduce eyestrain by alerting you when the device is held too close to your face.
