What is the purpose of compound eyes and simple eyes?

Compound eyes are essentially large clusters of simple eyes that are functionally capable of discerning images, whereas simple eyes only detect changes in light level. Compound eyes are found in many types of arthropods, and range from the relatively simple to the very complex.

What is the function of compound eyes?

The compound eye is excellent at detecting motion. As an object moves across the visual field, ommatidia are progressively turned on and off. Because of the resulting “flicker effect”, insects respond far better to moving objects than stationary ones.

What is the difference between simple eyes and compound eyes?

Compound eyes are made up of clusters of ommatidia, but simple eyes are made up of only one single unit of eye. Compound eyes are found in most of the arthropods, annelids and molluscs. Compound eyes can cover a wider angle compared to simple eyes.

What is the disadvantage of compound eyes?

Compound eyes generally have only a short range of detail vision. They are very near-sighted, and can see clearly only a few millimeters in front of them with any degree of fine resolution. On the other hand, the near-sightedness of insects is so extreme that they can see detail where we would need a microscope to see.

What is the difference between compound eyes and Ocelli?

Ocelli (singular Ocellus) are simple photo-receptors (light detecting organs). Unlike compound eyes, ocelli do not form a complex image of the environment but are used to detect movement. Most arthropods possess ocelli. Some species of arthropod do not possess compound eyes and only have ocelli.
