So far, all of the time's we've seen Gojo-sensei, his eye's have been covered by some patch/bandage/blindfold. Is it cause he is blind and hence wants to conceal some terrible injury he probably got from a battle? And if so how come he can still fight perfectly.
If not why does he prefer to cover his eyes, even while in battle. Also, how can he still move around perfectly with the blindfold, it most definitely is not completely transparent.
