Some animals, like humans, have two eyes on the front of the head that perceive a mostly overlapping visual field. In contrast, some herbivores (rabbits, for example) have eyes on the sides of their head and visual fields that may not overlap at all. How does position of the eyes in the head impact perception of the environment?

Having both eyes on the front of the head allows for a greater degree of stereoscopic vision, which leads to better depth perception. With eyes on the side of the head, there is less overlap between the visual fields of each eye, leading to less depth perception. However, this design also allows for a wider field of view to detect potential predators, as the animal can see in a nearly 360-degree range without having to move its head. Therefore, humans have better depth perception and a narrower field of vision than rabbits.
