Question

If somebody has 20/100 vision, this means?

1) They can see objects at 20 feet that a person with normal vision can see at 100 feet
2) They can see objects at 100 feet that a person with normal vision can see at 20 feet
3) They can see objects clearly at a distance of 20 feet
4) They can see objects clearly at a distance of 100 feet

Answer 1

A person with 20/100 vision can see at 20 feet what a person with normal vision sees at 100 feet, indicating poorer than normal visual acuity.

Step-by-step explanation:

If somebody has 20/100 vision, it means that they can see objects at 20 feet that a person with normal vision can see at 100 feet. This is a way to quantify visual acuity and it indicates that a person with 20/100 vision has poorer than normal vision. To have 20/20 vision, for example, is to have what is considered normal visual acuity, where the smallest letters that someone can read at 20 feet are the same as what a normally sighted person can read at the same distance.
