Technically, it is NOT considered perfect vision. 20/20 is considered nominal vision and is a value that represents an accepted level of visual acuity for a human. It means that at 20 feet, you can see things the average person will see at that distance. Good vision would mean the the bottom number is smaller, you can see at 20 feet what most people can see at 15 or 10. 20/40 would mean that you have to be at 20 feet to see what a normal person sees at 40 feet. Most places define blindness as 20/200.

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.
All 2015 means is that a person with 2015 vision can clearly see somthing 20 feet away that most people would need to be no more than 15 feet from. To this end, it is better. A person with 20/100 vision can see something 20 feet away that most people could normally see 100 feet away. --Yes, 20/15 is better vision than 20/20.
It means that a person needs to be within 20 feet to clearly see what someone with "normal" (20/20) perfect vision can clearly see at 25 feet. It's good but not perfect vision
A person with 20/20 vision can read an eye chart at a distance of 20 feet. A person with 20/40 vision can't and has to get closer to the eye chart. A person with 20/20 vision can read at 40 feet what a person with 20/40 visionAnswerIf you have 20/40 vision, it means that when you stand 20 feet away from the chart you can see what a normal human can see when standing 40 feet from the chart. That is, if there is a normal person standing 40 feet away from the chart and you are standing only 20 feet away from it, you and the normal person can see the same detail. 20/100 means that when you stand 20 feet from the chart you can see what a normal person standing 100 feet away can see. 20/200 is the cutoff for legal blindness in the United States.
