What do simple eyes see?

Do humans have complex eyes?

Our eyes are some of the most complex structures in all of nature. The human eye can take in a million simultaneous impressions and can tell the difference between eight million different colours. On a clear, moonless night it can also detect a match being struck 50 miles away.

What are simple insect eyes called?

ocelli
Simple eyes – ocelli (singular – “ocellus”) are “stand-alone” eyes made up of a lens, photoreceptors/sensory cells, and a connection to the ocular nerve (there’s a second kind of simple eye that’s restricted to the larvae of insects with complete metamorphosis, but we’re not going there).
