Reading all the way to the bottom I gather that 20/20 is perfect eyesight, but what does it stand for?
I thought that maybe 20 was referring to 20 %, which would be really bad!
I have close to 0.0 on both eyes (which means "perfect")...
And laser surgery btw is really common these day for people with ordinary seeing problems.
