It is interesting that we have broader view in horizontal axis than vertical axis, and my guess based on the theory of revolution is that because humans stand on the ground, most of the time the threats or things to notice come from left or right, so we developed better horizontal views.

About the blind spot, something very interesting you can do is cover up one of your eyes, then hold out your thumb at arms length. Stare at one spot, and move around your thumb in your field of view until you can't see it anymore. Now it's in your blind spot.
