Currently there are a lot of accessibility barriers that prevent blind people from interacting with VR environments.
Uhh.. Yeah. Virtually moving around a non-physical location with only audio cues has to be ridiculously difficult. For sighted people, vr adds another level of immersion. For blind people, it will add another level of abstraction.
And given that nearly all of the controller bindings are taken up by different descriptions, this still leaves nearly every other vr environment inaccessible to blind people.
