Why do bats have eyes if they can't see?

Despite the famous idiom, bats aren't blind. All bats rely on sight to find food, avoid predators and navigate to and from roosts. As expected in a nocturnal mammal, their eyes are heavily loaded with photoreceptor cells called rods, which maximise their ability to see in the dark.

If someone is as blind as a bat, they are nearly or completely blind or they are unwilling to recognize problems or bad things.

Is it possible for a bat to be blind?

Bats are not blind but their eyes see best in dim light. Usually bats use sounds and echoes, instead of eyesight, to find their way around at night.

How are bats able to hunt in the dark?

Bats hunt in the dark using echolocation, meaning they use echoes of self-produced sounds bouncing off objects to help them navigate. But that doesn't mean that bats can't see. Contrary to myth, bats aren't blind. In fact, research shows that depending on the circumstances, bats sometimes prefer using eyesight to sound when hunting.
