why does gojo wear a blindfold

Gojo Satoru wears a blindfold because of his special ability called the "Six Eyes," which allows him to see cursed energy in extreme detail. This heightened vision consumes a massive amount of his energy when his eyes are uncovered, causing him to tire quickly. Wearing the blindfold helps him conserve energy while still being able to sense the world and cursed energy around him by the residue and flow of cursed energy. Essentially, the blindfold acts as a protective measure against sensory overload and excessive energy drain, allowing him to use his powers efficiently without exhaustion. Additionally, Gojo can still see clearly through the blindfold due to the Six Eyes, which function like a high-resolution thermography, enabling him to perceive cursed energy even when his eyes are covered. He removes the blindfold only when he needs to unleash his full powers. Thus, the blindfold is both a practical tool for managing his energy and a distinctive part of his character design in "Jujutsu Kaisen".
