"The visual field of the human eye spans approximately 120 degrees
of
arc.
However, most of that arc is peripheral vision. "

https://en.wikipedia.org/wiki/Vision_span

Wikipedia contradicts itself in another article:

No, the difference is whether you are talking about one or two eyes.

No, with one eye it says 100-110 degrees outwards and 60 degrees towards
the nose. That makes 160-170 degrees.

Anyway, we were discussing sight, not sight with one eye shut. We were
discussing how far round you can see an object when looking straight
ahead.

I presume "when looking straight ahead" means without swivelling your
eyes.
Maybe there should be two sets of figures with/without swivelling,
because
when you detect something on the periphery, you look towards it (by
swivelling the eyes) and then see a bit further round in that direction.

200 degrees sounds incredibly high, but I've never tested my field of
view.
I would have guessed that it would be slightly under 180 degrees - but
that
it a guess without any testing. Maybe it *is* a realistic figure...

Easy enough to test yourself. I can see past right angles. I guess some
people are more or less than others, but I wouldn't think by much.

Now what probably varies considerably is people's 3D field of view - if
you have a large bridge on your nose, it will obstruct the view from one
of your eyes.

Perhaps this is why people with cute little noses do better in a lot of
sports.

What is the evidence that they do ? Can you list some example of
individuals like that ?
