I've always wondered...

[joelmckenzie]

I've always wondered about what happened to one of Deidara's eyes. Could you guys please tell me?

 

[Ldude]

Yes, actually Kishi told me all about Deidara's background... give me a minute to try to remember...

Nothing. Just a device he uses to counter genjutsu. He can attach it and take it off.

 

[joelmckenzie]

Wow, I guess that's how much he wanted to beat Itachi. A personal device to use against one ninja.

No. His eye was specifically trained against genjutsu. The device was a range finder for seeing greater distances when flying. It had nothing to do with genjutsu disruption.

Deidara trained his eye to not fall into genjutsu so he can beat Itachi.
