What is another word for simple eye?
Pronunciation: [sˈɪmpə͡l ˈa͡ɪ] (IPA) 
The term "simple eye" refers to an eye or visual organ that lacks a lens, such as those found in vertebrates or more complex organisms. Synonyms for simple eye could include "ocellus," "stemmata," or "eye spot." An ocellus is a small, single-lens eye found in many invertebrates, such as insects or arthropods. Stemmata, on the other hand, are single, light-sensitive cells found in some insects and crustaceans. These cells are not considered true eyes but can detect light and movement. Eye spots are also single, light-sensitive areas found in some aquatic organisms, such as jellyfish or sea anemones, and are used for detecting light and dark environments.
