Yeah, why do some animals have their eyes on the side of their heads instead of in front??
Just in case you're looking for an actual answer . . . (!!)
It's a tradeoff between being able to see a wide area around you (sides of the head) vs. getting good depth perception (front of the head = overlapping visual fields for the two eyes = depth perception). Prey animals tend to have eyes on the sides to keep an eye out for predators (e.g. rabbits) and predators tend to have eyes in the front to allow them to zoom in on prey accurately (e.g. owls).
