No,bats aren't blind. all bats can see, although some species aren't eagle-eyed. While scientist believe smaller bats don't see in color,many species get around amazingly well in the dark.Some bat species have the added advantage of enholocation-the ability to bounce sounds off an object,including prey,to determine its size,shape,& location.

Despite the popular saying, "blind as a bat," bats aren't blind at all. In fact, many species can see very well. But bats are specially adapted through echolocation to fly in absolute darkness, where they can find and snag insects for food. Echolation enables a bat to emit high frequency sound waves that bounce off an object, such as a tasty mosquito, to produce a type of sound "echo" that returns to the bat's ears. For a better idea of how this system works, visualize the last war movie you watched where a submarine equipped with sonar (sound navigation and ranging) emitted "pings" to detect surrounding objects underwater. The amount of time it took for the "ping" to sound helped determine the object's distance. This is similar to how a bat "sees" in pitch darkness, except the bat's hearing is so keen that it can actually tell one type of insect from another.
