The Sharingan is a special type of dojutsu (pupil technique) that naturally occurs in all members of the Uchiha clan, though not all of them gain the ability to utilize it. The Sharingan is thought to be descended from the Byakugan, but grants the user different abilities and a different insight.
Kakashi loses his sharingan after Madara takes it away from him. In the end, Kakashi gets the sharingan in both his eyes thanks to Obito's chakra. It was a temporary thing. So after Kaguya was sealed, his eyes reverted back to normal.
