So my left eye is somewhat nearsighted, but my right eye is way worse. My left one is measured at about 30/20, while my right one is about 140/20.
And while we're on the subject, is it possible to have vision better than 20/20?
Yes it is perfectly possible to have vision better than 20/20
I can't remember exactly how the units work in the US but in the UK we use 6/6 (exactly the same as 20/20) where you can resolve an image of height 6 cm at a distance of 6 metres therefore 6/5 is an image of 5 cm at 6 metres and 6/4 is 4cm and so on and so on
it's all down to the resolving power of your eye, the record I believe was set in the 1800's when a woman was able to resolve an object with a height of 1 cm at a distance of one mile, almost as good as an eagles eyesight...
