Simple eye in invertebrates: Simple eyes in arthropods, Ocelli or eye spots & Overview

A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from "compound eyes", which have multiple lenses; they are not necessarily simple in the sense of being…
