Moles and many cave dwelling or deep sea animals have poor vision. Some creatures such as worms and some amphibians don't have any eyes. Due to the fact that these creatures don't need to see, they have developed their other senses more than eyesight.
Contrary to popular belief, bats have average eyesight. They see as well as humans can see. Bats do, however, use echolocation to give them an advantage in the dark.
