Sensory disabilities like deafness and blindness are disabling because the world is not oriented to people with sensory disabilities.

I am reminded that the Deaf have their own mythology. American Sign Language is distinct; it's not English. Accordingly it has its own culture, including its own myths. Many of them are fables and stories from the western tradition slightly adapted. But some are original.

One common theme in American Deaf mythology (but I'd bet it's told elsewhere too) is stories about a world which is visually oriented. There's an ASL word for this world but English doesn't have one. Sometimes it's translated as Eyeth a.k.a. "Eye-Earth".

It's more than just a world where everyone is deaf or where everyone communicates in ASL. It has something like spiritual meaning to some of those who tell stories about it; in that world the Deaf are not disabled, not in the social way that matters.
