Dragonflies, marine predators, see much faster than humans. | science

So you might think that it is beneficial in nature for all animals to have fast vision. But this quick realization costs a lot of energy and is limited by the capabilities of the brain. Some animals need this energy to grow or reproduce.

According to the researchers, there is also a difference in visual speed within species. For example, soccer goalkeepers see changes faster than many other people, which is useful if the goalkeeper has to react quickly to an incoming ball. In addition, coffee can temporarily slightly improve the speed of vision.
