Try it out with a series of yes, yes, yes questions and watch carefully.
The eyes DO access somewhere.

Then try a series a of No, No, No questions and watch carefully. Your questions can't be the kind that can be answered "off the top of the head without thinking", so they have to be surprising questions that the subject must retrieve something to answer. And the eyes are not the only thing that responds -- as biofeedback will tell you if you go into that stuff (which can be absolutely marvelous as the body responds BEFORE the client can frame a verbal answer!).

The series of innocent yes, yes, yes and no,no questions it the basis for mentalism and
cold readings" done by fortune tellers and other cons. When you calibrate the body language you don't have to do much but just look at the person and study their answer.

To pass lie detector:

NLP Strategy to accomplish this might be designed thus: Create a full VAKOG experience internally & associate fully to it.Do this well enough & maybe when questioned about it your response maybe as if it is real.
