Apple's range of iOS devices and Mac computers are used by a significant number of vision impaired people. This is mostly due to Apple’s VoiceOver program, which is included on all current iPhones, iPads, iPod Touch. Apple Watch, Apple TV and Mac computers.
VoiceOver enables the user to interact with the device without the need to see what is on the screen. Apple has provided some information as to how VoiceOver works for the end-user:
