I have 3 possible reason about kakashi not going blind
1.Kakashi have uchiha blood line from his mother.We donot know much about his mother but if she had uchiha blood line ,enough for kakashi body to adopt the sharinganm.This will explain everything.
2.The sharingan blindness is more a curse on the uchiha clan but not a curse on non uchiha who have enough chakra to handle it power
3.Plain plot protection/PNJ/Plot shield by kishimoto to make kakashi look good as top class ninja but not as a fodder ninja
What u think?
