You’ll need to turn your magnifier on before you can use it, so head over to General > Accessibility > Magnifier. Then, you’ll hit your home button three times in rapid succession. This is how you’ll access the magnifier when you want to use it.

Once you’ve got it open, you’ll notice you can lock the focus, as well as turn on the flash (so perfect for menu reading in dark restaurants), plus add filters/

If you’ve been using your camera to help you in times you’ve forgotten your reading glasses, that’s cool too, but this is a totally different feature that actually functions waaaaay better than your camera.
