Compound eye
Compound Eye
A Compound Eye is a visual organ found in certain arthropods such as insects and crustaceans. It is made up of many small, simple eyes called ommatidia that together create a broad field of vision.
Pronunciation
/kɒmpaʊnd aɪ/
Etymology
The term "Compound Eye" is derived from the Latin words "componere" meaning "to put together" and "oculus" meaning "eye". This refers to the structure of the eye, which is made up of many smaller eyes or ommatidia.
Structure and Function
A compound eye is made up of many hexagonal lens-capped 'eye-units', or ommatidia, which are each capable of creating an image. This allows the organism to have a wide field of view and detect fast movements. However, the resolution is much lower than that of a simple eye.
