heres is what they had to say THIRD EYE BLIND – Our third eye is the imagined one that gives us a kind of sixth sense (telepathy, ESP, etc.) and the band felt that most of us are blind in that sense. There is also a symbolic third eye (all knowing eye) that appears on the back of a U.S. dollar bill.
Though other people have thought it was the other 3ed eye which is a eye only guys have it you get my drift.
Well i’m not 100% sure but you’re third eye is said to be in the middle of you’re forehead. It’s supposed to be the sours of all physic’s power. So i guess “third eye blind” means not physic or something.
Hope i helped!!!
I guss it means that ”eye of truth is blind”. Maybe you couldn’t see the truth when it in front of you.
