How compound eyes function?

Answer 1

"Compound eyes" are made up of lots of little eyes, each with its cornea, lens, and photoreceptor cells for distinguishing brightness and colour. They give the insect a wide field of view and, although they are extremely poor at picking out detail like a human's eyes can, they are excellent at detecting movement.

There are two types of compoundeye;

* Ones that form apposition images

* and ones that form superposition images.

Apposition favours sharpness and sacrifices brightness, while superposition favours brightness, but sacrifices sharpness.

Answer 2

Compared with single-aperture eyes, compound eyes of insects have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the polarization of light.Although insects' eyesight image is very poor,they can sense when there is reydators by using their five senses,just like humans,they are the sense of hearing,seeing,touching,tasting and smelling.

Answer 3

Visual receptor,senses light. characteristic of an arthropod.

Answer 4

The compound eye is one of the classical subjects in sensory physiology and neuroscience
