Question

Visual Development: What is considered optimal vision?

a) 20/20 vision
b) 20/40 vision
c) 20/100 vision
d) 20/200 vision

Answer 1

Optimal vision is often considered to be 20/20 vision, meaning a person can see letters from 20 feet that a person with normal acuity can also see from 20 feet.

Step-by-step explanation:

Optimal vision is often considered to be 20/20 vision. In this case, 20 feet is the distance at which the person being tested can see letters that are normally visible at 20 feet. So, if someone has 20/20 vision, they can see letters from 20 feet that a person with normal acuity can also see from 20 feet. If someone has 20/40 vision, they can only see letters from 20 feet that a person with normal acuity can see from 40 feet, and so on.
