Once the Zoom feature is turned on, you simply double-tap the screen with three fingers to zoom in. Don't squint, change your glasses, or hold the iPad close just to be able to see — turn the Zoom feature on, and use it when needed to see what's on-screen.

Go to a website and double-tap the screen using three fingers; it enlarges. Press three fingers on the screen and drag to move around it if you like. Double-tap with three fingers again to go back to regular magnification.
The Zoom feature works almost everywhere in iPad: in Photos, on web pages, in your Mail, in iPod and Video — give it a try!
