Due to fact that retina does not go to the front, we see about 169 degrees with each eye. We actually see 208 degrees, with 130 degrees of overlap. Notice this by closing one eye then the other, looking at something nearby. Still we combine views in our head. Look at a distant object with your thumb in front of you.
More overlap gives more depth perception.
Again, you have predator eyes. More important to se one thing clearly than to have a poorer view of a large region. Eye towards the top of the head. We perceive depth by many kinds of clues. Can or cannot be duplicated in a painting Magritte painting 8.2.
