This would mean, blocking signals from the eyes to the brain of the target, which in the case of dojutsu users, means they can't use it. I assume this technique was created to directly counter Sharingan users. it blinds the target with genjutsu yes, but at the same time it doesn't work in a way that dojutsu users can't counter, it clouds the vision nothing more, Sasuke's Rinnegan was able to resist infinite Tsukuyomi a Rinnegan that powerful isn't going to be affected by that level of genjutsu.

@Narutopwnu7 when was it stated or shown that Hiruzen is a sensor?
