Differences to the animal world
The type of vision described above refers to the visual perception of humans. Neurobiologically, this form hardly differs from perception in vertebrates and molluscs. Insects and crustaceans, on the other hand, have so-called compound eyes.
These consist of about 5000 individual eyes (ommatids), each of which has its own sensory cells. This means that the angle of vision is much wider, but on the other hand the resolution of the image is much lower than in the human eye. Therefore flying insects have to fly much closer to seen objects (e.g. cake on the table) to recognize and classify them.
Also the color perception is different. Bees can perceive ultraviolet light, but not red light. Rattlesnakes and pit vipers have a heat radiation eye (pit organ) with which they see infrared light (heat radiation) like body heat. This is probably also the case with night butterflies.
