There may come a time when you find that your close surroundings are increasingly difficult to decipher – and reading glasses alone simply don’t do the trick.

But unless you like to dress up as Sherlock Holmes, you probably don’t carry around a magnifying glass.

Fortunately, there’s a digital fix that you likely do carry: your iPhone’s Magnifier feature.

By enabling the Magnifier tool in your iPhone’s accessibility settings, you can zoom in on and magnify your surroundings by pointing your iPhone’s camera.

Here's how to turn on the Magnifier in your iPhone's Accessibility settings.

5. Now that the feature is enabled, you can click your iPhone's side button (iPhone X and later) or home button (iPhone 8 and earlier) three times to launch the Magnifier.

The Magnifier has a number of different options to help you see.

  • You can use the slider to zoom in and out.
  • Tap the lightning bolt icon on the left to turn on your flashlight.
  • The lock icon will keep the camera focused, and stop it from auto-focusing.
  • Tapping the large white button in the center will take a temporary photo, and freeze the image on your screen. Tap this button again to get rid of the freeze-frame.
  • Tap the three overlapping circles to add a filter to your camera, or adjust the brightness and saturation.
