Question

current attempt in progress
you learn that you have 20/50 vision after going to the optometrist. what does this mean?
o what someone with normal vision can see clearly at 50 feet, you need to be 20 feet away to see with the same clarity.
o for every 20 feet you see, there are 50 you dont.
o what someone with normal vision can see clearly at 20 feet, you can actually see at 50 feet with the same clarity.
o you can see 40% of what someone with normal vision can see.

Explanation:

Visual acuity is measured with a ratio. The first number is the distance at which the patient stands from the chart. The second number is the distance at which a person with normal vision can read the same line. So, 20/50 vision means what someone with normal vision can see clearly at 50 feet, you need to be 20 feet away to see with the same clarity.

Answer:

What someone with normal vision can see clearly at 50 feet, you need to be 20 feet away to see with the same clarity.
