Hello.

Judar's third eye opens during his fight against Aladdin in the Kou Empire arc. His power seemed to have substantially increased (as noted by Aladdin), though we didn't see its full potential, because Aladdin ended the battle prematurely by sending Judar off into space, thus rendering him unable to continue fighting.

I hope that answers your question.
