Well, there have been inconsistencies with Obito's intangibility. That being, Kamui is not actually intangibility, simply being warping parts of your body to Kamui's space-time area. Yet, Obito can whole-body slip through the ground without going back into the space-time area.

As for your point of Obito not being able to see, that would be logical if he is warping his head for Kamui. Isn't the whole mechanic of Obito's Kamui dependent on the predictive abilities of the sharingan? So, predicting an attack will hit you somewhere and warping that part of you away preemptively to avoid it. I don't see an issue with the mechanic, only the full-body usage.
