Question

Quizplus · Accepted Answer

Ian has the best visual acuity with 20/12 vision. The numerator represents the distance (in feet) at which a person can clearly see a letter or object, and the denominator represents the distance at which a person with "normal" vision can see that same letter or object. Therefore, the smaller the denominator, the better the visual acuity. Ian's denominator is the smallest among the choices given, indicating that he has the best vision.
