To the general public, 20/20 vision means that you can see at 20 feet what an average person should be able to see at 20 feet.
If you had 20/100 vision, it would mean you would have to be 20 feet away from something to see it whereas other people would generally be able to see that same object from 100 feet away. You would have VERY POOR vision.
If you had 20/5 vision, it would mean you would see from 20 feet away those objects which people would generally have to be within 5 feet of to see clearly. You would have EXCEPTIONALLY GOOD vision.
So the numerator (top number) is how far away YOU are standing to see clearly.
The denominator (bottom number) is how far away the AVERAGE PERSON would need to stand to see clearly.
