From its launch, iPhone has remained the most common and accessible phone for people with sight loss.
Today, both Apple and Android phones and tablets have built-in accessibility features. And you can run a screen reader or screen magnifier on most modern tablets that run on Windows 10.
For more information on iPhone accessibility, visit the Apple website.
