Apple iOS offers several features designed to protect eyes, such as Night Shift, True Tone, and Dark Mode. These can help mitigate blue light exposure and adapt screen brightness. iOS 17 introduces the proactive Screen Distance feature, addressing the challenge of prolonged device usage at close range. This optional feature sends a notification when the iPhone or iPad Pro is held too close to the eyes. The feature is aimed at reducing eye strain and the risk of nearsightedness, especially in young users.
Safety Check was introduced by Apple starting with iOS 16. Safety Check provides a way to stop sharing relationships on the iPhone. If your personal Apple ID has two-factor authentication enabled, you can check whom you're sharing information with and turn off sharing of Health, Home, Shared Calendars, Shared Location and Find My, Shared Notes, and Shared Photos.
