Probably a big part of it is that the high-resolution area of the retina is quite small. So in that small area, the perspective is close to perfect, and then we mentally stitch together a larger image by moving our eyes around. But the larger image that's stitched together is in the shape of a sphere rather than a flat surface, with each point on the sphere corresponding to a direction the eyes could be pointing.

Our eyes themselves move reasonably comfortably 15 degrees in all directions (maybe a little less up), but peripheral vision is greater in width than height and we are used to turning our heads to see objects in horizontal field of view more than vertical.
