Not really. Zuluhed isn't blind by any means. Unlike Drek'thar, who even in his Wow Appearance wears a blindfold.
Drek'thar is a Far seer.
Zuluhed is a Shaman/Warlock (a mix in between) not a Far seer.
Zuluhed the Whacked
I am saying this, because as a Far seer it would appear that most are wearing blindfolds. Maybe to better commune with the Spirits and the Elemental Lords.
It could be that i am wrong there. Far seer's have their own History. A bit long to explain it completely.
