Answer #1

Compund eye is the visual organ of insects. They consist of thousands of ommatidia that are photoreceptor units. Each one consist of cornea, lens and photoreceptor units. The image seen by the insect is a combination of inputs from each ommatidia. They orient to point at slight different directions thus caputiring light as individual units.Compund eyes of insects are better at alerting them the presence of a hunter.

Since they can look in many different directions at the same time and are sensitive to the movement of large objects.

Compared with single-aperture human eyes,

Compound eyes have poor image resolution

They possess a very large view angle.

They are able to detect fast movement

In some cases they can also detect  polarization of light.
