from looking at the definition of 20/20, 20/10 and 20/30, I think that it means that when looking at an eye chart or anything really, if it's 20 feet away, to you it looks like it's 300 feet away and therefore very blurry, as opposed to someone with 20/20 vision who sees it clearly. I'm speaking from experience as well, since I can't see clearly about a foot away from my face and the last time I checked my vision was 20/325 and 20/350 (I think)

What do the numbers 20 in 20 20 vision mean?
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.
