Human eyesight is pretty advanced. We can see red, blue, and yellow, and all the possible combinations of those colors. We can see in the daytime and at night, and we can focus on things that are close and far away. Many animals don't have all of those visual abilities, but they might also have other abilities which humans do not have, like seeing ultraviolet light or seeing heat.This series of animal vision videos gives you an idea of how animals see the world. For some, it's more blurry and muted; for others it's sharper or brighter. For still others, human vision would be an extremely disappointing downgrade. Take a look at how animals see, and think about which species you'd rather be.
