    Actually, 20/20 means that you do not have vision problems. It is also called Emmetropia, those that are neither nearsighted nor farsighted are able to see both far away and up close without vision correction. Though rare, some people have one eye with 20/20 vision while the other eye requires vision correction.

    This means that the test subject sees the same line of letters at 20 feet that a normal person sees at 20 feet. The people's normal vision should be 20/20. Hope this helpful.
