Some animals, like cats, can see much better in the dark than us humans. (However, cats can't see in total darkness, they just need about a sixth of the light our eyes need to see.) Other animals, like bats, use echolocation to "see" without any light at all. Some people have figured out how to use echolocation, but until we start genetically engineering our eyeballs to be more like a cat's eye, we'll have to use special cameras and sensors to see in low light situations (barring the use of flashlights). Here are just a few examples of some night vision tech.
