Genjutsu are mental jutsus. Meaning your mind is being affected. So for bringer of darkness (BoD), literally the signals of the target's brain to and from the eyes are being blocked. There is physically nothing wrong with the target's eyes, they just can't use them. IT was a visual genjutsu, but BoD isn't. I also initially thought that it would not affect dojutsu users, but it is described as guaranteed to have this effect. To say otherwise is to disregard facts.
