Note also that 20/20 vision isn't actually that high, especially if you're young, so the chart isn't necessarily definitive.
"a subject diagnosed as having 20/20 vision will often actually have higher visual acuity because, once this standard is attained, the subject is considered to have normal (in the sense of undisturbed) vision and smaller optotypes are not tested."
