An ant’s head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together.
Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization.
Compared to vertebrates, most ants have poor-to-mediocre eyesight and a few subterranean species are completely blind.
