I can tell when words lie to my third eye

from Capital STEEZ (Ft. Chuck Strangers & CJ Fly) – Cab Fare Lyrics 6 on Rap Genius

The Third Eye is a reference to an insivible eye in the forehead. It provides perception beyond ordinary sight that the two eyes we have can give.
So, we can interpret this line as STEEZ telling us he can say things beyond ordinary perception of man, something superior, something way more knowledge valued.
