Can blind people have a photic sneeze reflex?
gpt
I suppose it depends what type of blindness.  If they're blind from their eyes, completely, then they won't.  Though, if their occipital nerve is still sending proper signals, and the blindness is due to an irregularity in the occipital lobe, then it is possible, due to the reflex being a signal leak from the nerves in your eye and nose being extremely close to eachother.
