Jumping into the middle of this discussion:

One point to remember is that human eyes are a set of sensing instruments
in the service of the brain.
Brains process sensory input and do a lot of "anti-aliasing".
The image you perceive is a brain-processed image that is heavily influenced
by memory, interpolation, pattern recognition, imagination plus a little
'objective
data'.
