How Does Gojo See?

Via a translation of the Fanbook on Twitter, Akutami explained that while Gojo wears a blindfold, he can still see as a result of Cursed Energy. The Six Eyes is still able to see this energy in such detail that a blindfold doesn't matter.

Does Gojo see normally?

For example, Gojo's sunglasses are too dark for a normal person to see. Objects that lack cursed energy can be discerned through the blindfold by reading the residuals and flow of the cursed energy surrounding them.

Why does Gojo have his eyes covered?

So, why does Gojo wear a mask? Gojo needs to cover his eyes because using them would tire him out too quickly. He's got something called Six Eyes, which has been passed down in his family's bloodline. This is a rare type of ocular jujutsu.
