Question

John recently had his visual acuity measured using the Snellen Eye Chart. His results indicated that his vision is 20/15 in both eyes. Which answer best describes what 20/15 vision means? *

Answer 1

Answer:

The answer is below

Explanation:

Snellen Eye Chart was developed in 1862 by Dutch ophthalmologist Herman Snellen, to determine if humans have a normal vision which is rated at 20/20

However, in the case of John, a 20/15 vision means John can see a line in the eye chart at 20 feet away that the average person can only see when they are 15 feet away.

This shows John has a sharper than average visual acuity.
