No there is not a single species of bat that is blind. All bats can see and the idea that bats are blind probably comes from the saying â€śas blind as a batâ€ť or from the fact that some bats have poorly developed or small eyes. Because of this, they will have poor acute vision but certainly not blindness.
The old saying â€śas blind as a batâ€ť is misleading.
Some bats rely on vision for their navigation and some bats can even detect ultraviolet light.
Bats also have other highly sensitive and developed senses. They use these senses to their advantage during the night to outsmart prey when they hunt.
