Perfect vision
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
It means you have pretty close to perfect vision as 20/20 is considered perfect. Simply put, most people see at 25 feet what you see at 20.
Not likely. While perfect vision or even near perfect vision are necessary for enlistment, enlistees cannot be legally blind.
Hind sight refers to something that has happened. 20-20 vision describes perfect vision. If we know the results (because it has happened), we surely have "perfect vision" about that event. Hence the saying: it has happened, therefore we know it. Opposite: we cannot know what will happen in the future, so we might describe our future vision as poor.

The Great Society
Perfect vision is not required to enter the 2020 olympics. As song as you are still able to be competitive, the olympics don't care about your vision. If your vision is poor enough to limit your ability to compete with people with better vision, there's always the paralympics.
that means that you have perfect vision__________________________________________________________The numerator refers to within what distance of certain objects you have to be to distinguish them. The denominator refers to within what distance of certain objects a "normal" person has to be to distinguish them. Therefore, 25/25 vision is much like 20/20 vision in that it indicates normal/perfect vision. If the numerator is greater than the denominator (20/15), one's vision is better than normal. If the denominator is greater than the denominator (20/40), one's vision is worse than normal.
Everything in the world is perfect and everyone is perfect in some way as he is in sports
Utopia
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.
