They don't, or at least not any better than cats.
What they do have is sonar - echo location - by which they can detect obstacles and food in total darkness.
Bats have eyes and can see both at night and during the day using their eyes. However bats do not rely on their eyes at night (in the dark), because they have another sense they use called "echo location" which works better than their eyes.
Bats can see perfectly well at daytime because they are just like any other animal. People think bats are blind because they don't use their vision at night. They use a process called echolocation, a process where the bat emits a sound from its mouth that bounce off objects when flying.
Bats primarily use echolocation, emitting high-frequency sound waves that bounce off objects in their surroundings. They then detect the returning echoes to navigate and locate prey in the dark. This ability helps them "see" in the dark and hunt for insects at night.
Because they're nocturnal (: they sleep in dark places during the day time, like caves. They come out at night.
what determines the portion of the moon that you see at night
no not all bats are blind ... .... .... new answer .... OK no all bats are able to see the reason they use sonar is because that they see the same way humans do... they use cones and rods in their eyes, which can't see at night, so there fore... bats are not blind they are more able to see than we are. They are just nocturnal so that they are only out during the night. And thus bats cant see at night even though they can see perfectly normal.No they are not blind, but they have little need to use their eyes to know where to fly. Bats can 'hear' their surroundings by sonar and therefore can 'see' at night.
yh take the owl for example and bats , bats can ONLY see in the dark :)
Bats can't see very well, they use sonar
Bats can see during the day, but their vision is not as sharp as their night vision. They rely more on echolocation at night to navigate and hunt for food.
at night when they hunt. They sleep during the day and wake at night(nocturnal).
The two main reasons is firstly there is less competion for food at night, so they can feed easier. Also its harder for a preadetor to see them, so they are saver Actually I am wrong. Bats are nocturnal. They can see at night and their prey is out only at night.

This is a answer to a bat one. Bats can see at night because they have something in their body that bounces off to an object and tells them that that is blocking it.
That is why owls has very big eyes.. they can see anything.. Common Sense
because bats and owls could see and fly at night
bats can see in day time, but (like us) not at night. They use ECHOLOCATION. See the discussion page to see what echolocation means.
they use echolocation. they go out at night so prey wont see them
