Question

Quizplus · Accepted Answer

Normal vision is defined as having 20/20 vision, which means that you can see at 20 feet what the average person can see at 20 feet, or in other words, you have average visual acuity. Therefore, choice A is correct. The other choices are incorrect because they either refer to distances that are not standard for measuring visual acuity (such as 15 or 30 feet), or they imply that the person with normal vision has above or below average visual acuity (such as choice B which suggests that their vision is twice as good as the average person's).
