the human eye is spherical and envelopes a spherical image, but your brain tells you no, it doesn't. you can best take part in the way the eye really sees by approaching a very straight and long wall that has parallel lines adorned and best approached if said lines are at eye level. approach the wall perpendicularly with one eye closed and you will see that the wall curves away as if peering into a fish eye lens.
