The "Faceted Eye" is a type of eye structure found in many arthropods, including insects and crustaceans. It consists of numerous small units called ommatidia, each functioning as a separate visual receptor. This design allows for a wide field of vision and the ability to detect motion effectively, making it advantageous for survival in various environments. Faceted eyes are particularly prominent in species like dragonflies and bees, which rely on their acute vision for hunting and navigation. The compound nature of these eyes enables them to perceive a broader spectrum of light, including ultraviolet, which is invisible to humans.
