Bats are blind.

The information published by the U.S. Geological Survey (USGS) and the National Park Service (NPS) refutes the claim that bats are blind.

Contrary to myth, bats aren't blind. Research shows that depending on the circumstances, bats sometimes prefer using eyesight to sound when hunting. Many fruit bats, which drink nectar rather than hunt insects, don't echolocate, meaning they use echoes of self-produced sounds bouncing off objects to help them navigate, at all. These species have particularly sharp vision, and some can even see ultraviolet light. In fact, some of the larger, fruit-eating bats can see 3 times better than humans.
