Each eye is a small camera, and the surrounding objects are constantly ingested to form images. It can see things up to 6 meters. The whole compound eye is spherical, and its curved surface can take care of all directions, and the dragonfly's large head can rotate freely, so that the dragonfly's field of vision is very wide.

In addition, their compound eyes can measure speed. When an object moves in front of the compound eye, each "small eye" reacts in turn, and the speed of the target object can be determined after processing.

Dragonflies are compound eyes, innumerable.

Dragonflies have 28,000 small eyes per compound eye, which are shared by both compound eyes10,000 glasses.

The dragonfly in nature is a compound eye, the compound eye of the dragonfly is the largest and most in the insect world, accounting for 2 3 of the entire head, and the two large compound eyes of the dragonfly are composed of 28,000 small eyes, so there are 10,000 dragonfly eyes, which is 10 times that of ordinary insects.

As the animal with the most eyes in the world, dragonflies not only have many eyes, but each eye has its own system, each with its own refractive system and sensory cells, so it has vision.

The compound eye is relative to the monocular eye and is made up of most small eyes. Each eyelet has a cornea, crystal vertebrae, pigment cells, and retina.

Structures such as cells and rods are independent photoreceptors. Axon.

It protrudes posteriorly from the retinal cells and crosses the basal membrane to form the optic nerve.

The structure of the dragonfly's eyes is also very special. A small eye in the upper part of the compound eye that specializes in seeing distant objects. The small eyes in the lower part are dedicated to looking close.
