    1. Step 1. Make text larger and bolder

      Open Settings, tap Accessibility, then tap Display and Text Size. Turn on Bold Text. Tap Larger Text, turn on Larger Accessibility Sizes, then drag the slider all the way to the right for the biggest setting. Tap Increase Contrast to make text stand out from backgrounds. These three changes affect almost every app, including Messages, Mail, Safari, and the App Store.

      Quick Tip

      Quick Tip: If the largest size is still too small, also turn on Zoom in the next step for an extra magnification layer.

    2. Step 2. Turn on Zoom for screen magnification

      Open Settings, tap Accessibility, then tap Zoom and switch it on. A floating Zoom controller appears. Tap it once to zoom in, tap and drag to pan around, and double-tap with three fingers to zoom further. Choose Full Screen Zoom or Window Zoom from the Zoom Region menu. Window Zoom is friendlier for beginners since it leaves part of the screen at normal size for context.

    3. Step 3. Use Magnifier as a portable magnifying glass

      The Magnifier app comes pre-installed on iPhone and iPad. Open it from the home screen, or add it to Control Center by going to Settings, then Control Center, then tapping the plus next to Magnifier. Inside Magnifier, drag the zoom slider, tap the flashlight icon to add light, and tap the filter icon to switch to high-contrast modes like yellow on black, which many people with AMD find easier to read.

    4. Step 4. Try VoiceOver for hands-free reading

      VoiceOver reads everything on the screen aloud. Turn it on in Settings, Accessibility, VoiceOver. Once on, swipe right with one finger to move to the next item, double-tap to open whatever is selected, and use two fingers to scroll. Practice in the built-in tutorial under VoiceOver Practice. Many seniors keep VoiceOver off for daily use and trigger it with a triple-click of the side button only when their eyes get tired.

      Warning

      Heads up: VoiceOver changes how taps work. Until the gestures feel natural, practice on the home screen rather than inside Mail or Messages.

    5. Step 5. Use Detection Mode to read labels and find doors

      Open Magnifier and tap the Detection icon, shaped like a small box with a dot inside. Point the camera at a prescription bottle, a can of soup, or a sign — the iPhone reads the label aloud. Switch to Door Detection in the same menu to hear how far away the nearest door is, whether it is open or closed, and any room numbers on it. Detection Mode is available on iPhone Pro models with the LiDAR sensor.

    6. Step 6. Add Accessibility Shortcut for fast access

      Set up a triple-click of the side button to toggle the most-used features on and off. Open Settings, Accessibility, scroll to the bottom and tap Accessibility Shortcut. Pick Zoom, VoiceOver, Magnifier, and Color Filters. After saving, three quick presses of the side button shows a menu to pick which feature to turn on. This puts accessibility one button away rather than buried in settings.

    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.
