Compound eye — Senses Vespid wasps (Vespidae), similar to other insects, have compound eyes that consist of thousands of tiny optical units known as ommatidia, which contain light-sensitive photoreceptor cells.

Predators, such as felines and owls, possess forward-facing eyes that allow them to judge distance through a process known as binocular triangulation.1

Because these eyes are positioned to face the same direction, they provide overlapping fields of view. This overlap enables the brain to compare the slightly different images captured by each eye, which is essential for accurately perceiving depth and distance to targets. This configuration contrasts with that of many herbivorous species, which typically have eyes placed on the sides of their heads to maximize their field of view and detect potential threats from almost any direction.12
