20/20 is description of visual acuity measured in feet that is equivalent to 6/6 if measured in meters. It tends to be described as "this person can see at 20 feet what the normal person can see at 20 feet", 20/10 is "this person can see at 20 feet what the normal person can see at 10 feet".
I do get visual overloads, though primarily from bright lights and blinking lights. The flashing of florescent light bulbs is terrible, headlights cause me to overload so easily that I doubt I'll ever be able to drive. Busy patterns are more likely to distract me that overload me, as I try to figure every last detail out. I'm not sure whether crowds bother me visually because I'll avoid them for other reasons, and all of my senses are hypersensitive.
I've always thought that my good eyesight and my visual sensitivities were strongly connected.
Thank you for your explanation!

But I believe the point they were trying to convey in the German article was not so much one of having superior developed eyes anatomically, so much as one of noticing details. "Taking closer notice" rather than "having sharper focusing eyes."
Just as the recently blind develop "enhanced" senses of touch and hearing.
In the last sentence they give a kind of suggestion: "New in the findings is the degree of deviation - and that it is based not only on a higher sensitivity, but also on physical qualities.", but I don't think either that it's anatomically meant. Also the answers here show that everyone is different. But still there is this somehow increased sensivity of senses in all of us, I guess. But what you, Burnbridge, write "Just as the recently blind develop "enhanced" senses of touch and hearing.", then I wonder if the senses get "enhanced" because of "missing" other abilities [like not being able to "read" the world in a comforting way develops increased sensitivity, because one feels more "in danger"].
