iPhone and iPad Accessibility for Low Vision

Apple builds a deep set of vision accessibility features directly into every iPhone and iPad. None of them require an extra app, none cost money, and most can be turned on in under one minute. The features were designed with input from people who are blind or have low vision. So they actually work for daily tasks like reading text messages, recognizing money, finding the bathroom in a strange building, and reading a prescription bottle.

The most useful tools for low vision fall into four groups. First, text size and bold settings make the words on screen larger and thicker. Second, Zoom magnifies any part of the screen up to 15 times. Third, the Magnifier app turns the iPhone camera into a high-powered magnifying glass with adjustable lighting and contrast filters. Fourth, VoiceOver reads the screen aloud and lets the user navigate by touch — useful when text is too small to see at all, or when the eyes are tired.

Newer iPhones and iPads also include Detection Mode inside Magnifier. Detection Mode reads aloud labels on bottles and cans, describes the scene in front of the camera, identifies people who are close by name if they are in the photo library, and finds doors, signs, and text in the surrounding area. These features work without an internet connection.

A short setup session, often with help from a younger family member, can transform an iPhone from frustrating into the most useful tool in the house. The settings stick — once VoiceOver, Zoom, and large text are configured, they stay on every day.
