In this article I will try to give some insight into the ways an insect sees the world. In contrast with our eyes, insect eyes are immovable and unable to focus.
Insects are short sighted.
Butterflies are probably the most far sighted, they can see perhaps a few meters, while bumblebees only have a range of a half meter. But many insects are helped a lot by their sometimes unbelievable sensitivity for scents. It is of course impossible for humans to perceive what an insect sees. In most cases the compound eyes will see only form and movements, but the dragonfly , who has to catch his prey in flight, undoubtedly must have a detailed view of his near surroundings. Insect eyes can change considerably between the larval and the adult stage.
