I saw a great post about the difference on tumblr. Basically, audio books are reading. But they do not improve literacy; if you are sighted just listening is fine but it is important to read letters visually because literacy is really important to navigate society. Blind people also need to learn literacy; braille. And the lack of access to braille services is already terrible and with the rise of audio formats its gotten worse. But if a blind kid only uses audiobooks they can’t read braille 1/2
