| One huge problem you have.. other than being a liar.. is that you
accept the ideas of some people too easily - while you reject the
conventional wisdom of rational people.
You can debate how well a human eye can see.. but the point is, there
is a limit to how well one can see due to the size of the eye, the
shape, and how the visual information is processed. That number has
been estimated to be 20/8
In vision.. There are basically 3 types of vision.
The most limited field of vision is where you see the structure of
what you are looking at, Beyond that field, you can still see color
and light, but you can't distinguish the shape of what you see. Beyond
that is the peripheral vision where you can't see shape nor color, but
you can detect motion - much like a bug. Bugs are great at detecting
motion and not much else. Try this with a cockroach or with Keller.
They can't see you as long as you don't move.
Try this.. without turning your head at all.. hold your arms out and
look to the left and right with your eyes.. without turning your head.
You can't count your fingers.. however if you wiggle your fingers..
you can detect the motion. Move your arms back even further.. and
you can still detect the motion. I have extraordinary peripheral
vision. I can detect motion to a field of about 270 degrees -
although I have not measured. Myopes have steepened eyes which
allow for greater peripheral vision.
Hopefully in time you will learn whom to pay attention to and stop
making a fool of yourself. I don't think you are interested in
reality though... you only are interested in misleading people for
some peculiar agenda.
