Compound eyes are organs of vision in arthropods (insects and crustaceans). A compound eye is characterized by a variable number (a few to thousands) of small eyes, ommatidia, which function as independent photoreception units with an optical system (cornea, lens and some accessory structures) and normally eight photoreceptor cells.

Grasshoppers' compound eyes function not only to pick up on motion and basic form, but also to discern the distance between their bodies and other things -- perhaps sources of food, for example. Grasshoppers' eyes are not capable of moving like those of humans.

Arthropod eyes are called compound eyes because they are made up of repeating units, the ommatidia, each of which functions as a separate visual receptor. Each ommatidium consists of a lens (the front surface of which makes up a single facet) a transparent crystalline cone

Both the insect compound eye and the human type of eye have lenses and light-sensitive cells that allow the eyes to collect data that a brain can form into an image of the surrounding environment. Where insect eyes have many tiny lenses with one lens per ommatidium, or eye subunit, the human eye has a single large lens.

Apposition eyes are the most common form of eye, and are presumably the ancestral form of compound eye.They are found in all arthropod groups, although they may have evolved more than once within this phylum. Some annelids and bivalves also have apposition eyes. They are also possessed by Limulus, the horseshoe crab, and there are suggestions that other chelicerates developed their simple eyes ...

en.wikipedia.org/wiki/Eye

A compound eye may consist of thousands of individual photoreceptor units or ommatidia (ommatidium, singular).The image perceived is a combination of inputs from the numerous ommatidia (individual "eye units"), which are located on a convex surface, thus pointing in slightly different directions.

Compound Eyes vs Simple Eyes Simple eyes and compound eyes are two main types of eyes found in animals, and there are many differences between each other. In order to understand whether a particular eye is a compound eye or a simple eye, it would be worthwhile to go through some information about those.

What Is the Purpose of Compound Eyes? Compound eyes give insects an expanded field of view, according to University of Minnesota (UMN). Compound-eyed insects, such as the dragonfly, can see objects from all angles except for the blind spot their bodies create. Some boast dual-vision systems which allow them to see darkness, light and color.
