A bee is an insect with complex vision. It has five eyes: two multi-faceted large eyes and three simple eyes, which are located on the back of the head of the insect.

The compound eye is about 6, 000 independent small-sized eyes (facets). Bees need these eyes in order to identify places where you can collect nectar, to navigate outside the nest. Bees need simple eyes for orientation inside the hive. Drones have up to 8000 facets, their eyes are even more difficult, since drones must track the uterus during mating flight.

Faceted vision is also called mosaic, since the final image that the bee receives is made up of individual images obtained by each facet.

The experiments with bees were carried out by scientists in various conditions, as a result it was found that the bee's eye perceives shorter light waves than the human eye. Bees see not only the range from red to purple, they also see ultraviolet waves.

Based on this, it can be concluded that bees see more shades than people, and insects distinguish flowers that seem to be the same to us. In any case, flowers, white for humans, for bees have different shades. However, scientists have found that bees do not distinguish red, and it could be assumed that shades of red seem black to them. But everything is not so simple, the red color, if you look closely at it, has some part of the blue halftones, and the blue bees see well. It turns out that if a person could see the flowers as bees see them, they would seem to him much more beautiful. That is, the poppy flower for a bee is not red, but "ultraviolet."

Bees distinguish up to 200 flashes of light per second, while humans only 20. This makes it possible for bees to communicate with each other, they actively move in the hive, move their legs and wings quickly, and the person practically does not notice these movements, and the bees see them distinctly. This helps the bees to accurately sit even on a swinging flower, clearly determining the distance to it.

However, the bee distinguishes only large objects. Despite the fact that she herself is tiny, when compared with a person, her eye is not able to perceive small details. A person sees objects 30 times smaller than those that a bee can see.
