manyeyed

Manyeyed, also many-eyed, is an adjective used to describe beings or objects that possess numerous eyes or eye-like organs. The form is commonly hyphenated as many-eyed in formal writing, while manyeyed can appear as a single word in certain stylistic contexts. The term derives from the combination of many and eye, with roots in English language development and classical storytelling traditions that emphasize heightened vision or vigilance.

In myth and folklore, the archetype of a many-eyed being appears most famously in Greek myth with Argus Panoptes, a giant said to possess a hundred eyes. According to myth, Argus could keep many of his eyes awake at once, and after his death Hera placed his eyes on the tail of a peacock as a memorial. This figure has become a symbol of omniscience and unblinking watchfulness.

In biology, many-eyed describes organisms that have more than two eyes or numerous eye-like organs. Spiders commonly have six to eight eyes, though counts vary by species. Some crustaceans and other invertebrates bear multiple ocelli or simple eyes along their bodies. By contrast, many vertebrates retain a pair of forward-facing, complex eyes. The term is often used descriptively rather than taxonomically.

In modern usage, many-eyed can be metaphorical, signaling pervasive observation or surveillance, and it appears in science fiction and fantasy to evoke omnipresence or heightened perception. It is also used in discussions of sensor networks and multimodal vision systems to convey breadth of coverage.
