Why is perfect vision called 20 20?
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.
Is 15 15 vision better than 20 20?
I'm not an opthamologist, but I believe that 15/15 is no better nor worse than 20/20.15/15 means that at 15 feet distance from the chart, you see what the average person would see at 15 feet distance.20/20 means that at 20 feet distance from the chart, you see what the average person would see at 20 feet distance.Since some people have problems with distance vision (Myopia), and some people have problems with near vision (Hyperopia), it would seem possible for someone to have 15/15, but not 20/20, or vice versa.
