Idiom:  blind as a bat

  • to not be able to see or to not see well


This idiom can be confusing for some people because bats have eyes and can see with them!

In the dark (for example at night or in caves) bats can also “see” to get around or locate things by using their ears (they use echolocation). Perhaps that’s why this idiom came about.
