The 20/20 mark is “simply a point of reference,” says Dr. Other factors, such as peripheral vision and depth perception, go into determining whether your vision is ideal. There’s “more to eye care than 20/20 vision,” says Barbara Horn, president of the American Optometric Association. While 20/20 vision is normal, it is not perfect vision. But if you have 20/100 vision, you must be as close as 20 feet to see what a person with normal vision can see at a 100-foot distance. So, if you have 20/20 vision, you can see clearly at 20 feet what typically should be seen at that distance. The American Optometric Association explains that 20/20 vision refers to someone’s visual acuity - the clarity or sharpness of vision - measured at a distance of 20 feet without vision correction (such as eyeglasses or contact lenses). Is 20/20 really “normal, good vision”? Technically, yes. So, in this year focused on good vision, let’s answer some common questions about 20/20 vision, other levels of visual acuity and how less-than-good vision can be corrected to 20/20. "Even though it is not the very best visual acuity, it is the standard most people use when referring to good vision,” he adds. What better year than 2020 to focus on 20/20 vision, the importance of regular eye exams and how to maintain overall eye health?Īs Burt Dubow, OD, FAA, an All About Vision editorial advisory board member whose cellphone's last four digits are 2020, says, “2020 is an iconic number for all eye folks.
