It's a baseline. You can see at twenty feet what most people can see at twenty feet. If you are nearsighted, the numbers go up: you might be 20/100, meaning you have to be 20 feet away in order to see something others could see from 100 feet. If you're really lucky, you could have 20/15 vision: you can see at 20 feet what most people have to be 15 feet away from to see.

No, 20/20 is considered perfect vision. I am suprised you are wearing glasses anyway. In most states your vision has to be 20/45 or worse for you to have to wear glasses to drive.

It means that while standing 20 feet from an eyechart, you can see what the average person sees standing 20 feet from an eye chart. You have average eyesight.

It means you see twenty feet, or, ten people. While most of us see two feet on one people.
