Obito Uchiha Narutopedia, the Naruto Encyclopedia Wiki

Obito and Kakashi are facing a Stone Ninja with camouflage abilities. He uses them and slashes Kakashi's eyes in the process. This leaves Obito crying and awakens his Sharingan. When the invisible Stone Ninja is coming up, Obito uses his Sharingan to track him down, then finishes him with a kunai.. Obito Uchiha (うちはオビト, Uchiha Obito) was a member of Konohagakure's Uchiha clan. He was believed to have died during the Third Shinobi World War, his only surviving legacy being the Sharingan he gave to his teammate, Kakashi Hatake. In truth, Obito was saved from death and trained by Madara, but the events of the war left Obito disillusioned with reality, and he inherited Madara's.

The mystery surrounding the antagonist Obito Uchiha and his eyesight has left room for interpretation for Naruto fans.. Madara stole Kakashi's left eye. Naruto healed Kakashi's left eye, making a new, regular eye. Madara took back his right rinnegan from Obito and - for some reason - gave his original right sharingan back to him. So Obito has both his eyes back. Obito is killed by Kaguya and turns to dust, along with both of his sharingan - they both disappeared.
