1. Resize Screen Elements

Adjusting screen size can help with visibility. You can resize screen elements to make text, buttons, and icons larger and easier to see.

Increase Text Size

  1. Open Settings.
  2. Go to Display & Brightness.
  3. Tap Text Size.
  4. Drag the slider to increase the text size.
  5. If you need even larger text, go to Settings > Accessibility > Display & Text Size > Larger Text, then enable Larger Accessibility Sizes and adjust the slider further.

Use Display Zoom for Larger Icons and Controls

  1. Open Settings.
  2. Go to Display & Brightness.
  3. Scroll down to Display Zoom and tap View.
  4. Choose Larger Text to increase the size of icons and interface elements.
  5. Tap Set and restart your device to apply changes.

2. Improve Contrast

Increasing contrast improves visibility, making text and elements easier to distinguish.

Enable Bold Text

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Display & Text Size.
  4. Toggle Bold Text on for thicker, more readable text.

Enable Increased Contrast

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Display & Text Size.
  4. Toggle Increase Contrast on. This enhances the difference between text and backgrounds, making content easier to read.

Reduce Transparency for Better Visibility

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Display & Text Size.
  4. Toggle Reduce Transparency on to make backgrounds more solid, improving contrast in menus and overlays.

3. Enable Dark Mode

Dark mode is useful for reducing eye strain. You can enable this mode for better visibility in low-light environments. There are also additional dark mode options available:

  • Classic Invert: Reverses all colours on the screen, making white backgrounds black and black text white. This is useful for users who prefer a fully inverted display.
  • Smart Invert: Similar to Classic Invert but maintains the colours of images, videos, and some apps that already use dark mode.

To enable these features, go to Settings > Accessibility > Display & Text Size and select the mode that suits you best.

4. Adjust Colour Settings

Changing colour settings can improve readability. If you have difficulty distinguishing certain colours, you can enable Colour Filters to customise the display to your needs.

To adjust colour settings:

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Display & Text Size.
  4. Tap Colour Filters.
  5. Toggle Colour Filters on and choose from options such as Greyscale, Red/Green Filter (for Protanopia), Green/Red Filter (for Deuteranopia), and Blue/Yellow Filter (for Tritanopia).
  6. Use the Intensity and Hue sliders to fine-tune the display.

5. Customise App-Specific Settings

Some apps allow individual accessibility settings for a better experience. For example, you can increase text size in apps like Safari, Mail, and Messages without affecting system-wide settings.

To adjust app-specific settings:

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Per-App Settings.
  4. Tap Add App and choose the app you want to customise.
  5. Adjust settings like Larger Text, Bold Text, Reduce Transparency, and Invert Colours for that specific app.

6. Reduce Transparency

Reducing transparency can make menus and overlays clearer and easier to read. To enable this:

  1. Open Settings.
  2. Go to Accessibility.
  3. Select Display & Text Size.
  4. Toggle Reduce Transparency on.

7. Use Accessibility Shortcuts

Accessibility shortcuts allow you to quickly toggle different visibility settings. To set up a shortcut:

  1. Open Settings.
  2. Go to Accessibility.
  3. Scroll down to Accessibility Shortcut.
  4. Select the features you want quick access to, such as Zoom, Colour Filters, Smart Invert, or Reduce White Point.
  5. Triple-click the side or home button to activate the shortcut.

By adjusting these settings, you can make your iPhone screen easier to see and use.
