Can I just surprise you there?
If you look at a wall and focus on a point which is far enough away
to be in focus (about 10 inches, but a reasonable distance for discussion
is about say 4 feet?) the image you can see in detail is round effectively
perfectly round. This is because visual sensitivity on the eyes retina is
round. (Consult any text book or google on fovea and macula).
And you can forget any two eyes arguement, both eyes are focused on the
same point, this is how our eyes work.
Yes the field of vison when moving your eyes is wider, due to the bone
structure of the face, but if I look between my legs I have 360 degrees
vision in the horizontal range.

Nothing down there either?



I actually have a copy of the Sun here
