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.
Because they're nocturnal (: they sleep in dark places during the day time, like caves. They come out at night.
The moon seems to shine at night, because it reflects the light given off by the sun. We can not see the moon's reflection during the day, because the sun light is too bright, but, at night, the moon reflects the light given off by the sun and we can see it.
During the day, the Sun is out and brightens the sky. Since the Sun is so close to Earth (compared to the stars we see at night), the Sun's light overpowers the light coming from the distant stars. However, at night the Sun's light is not present to wash out the light from the stars, so the stars can finally be seen. The constellations that one sees at night arises from the groupings of various stars.
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).

bats can see in day time, but (like us) not at night. They use ECHOLOCATION. See the discussion page to see what echolocation means.
because it would be pointless to light them in the day. You couldn't even see the light during the day.
Bats do not have night vision; they see very poorly at night and not all that well during the day, either. Those species of bats that eat insects use sonar to locate the insects, rather than vision.
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.
the pinworms know because of light if there is light on in that room they think its day but if they see know light it is night
The reason you can see planets and stars at night is that their light is faint and the brightness of the sun obscures them during the day. At night, when the sun is not visible, the fainter light from the planets and stars can more readily be seen.
Yes, but their night vision is way better, That's why they mostly sleep during the day and hunt at night .
Light is needed to see at anytime, day or night. However during the day there is usually plenty of light provided by the sun. During the night the sunlight is blocked by the earth and other than reflected light shining from the moon and the starlight one generally needs to create an artificial light source (e.g. candle, whale oil lamp, kerosene lamp, gas lamp, electric light) to get a usable amount of light to see well enough to perform useful tasks.
That means that basically you can not see if it is light or dark in a room. Or if it is night or day. You pretty much can not tell light and dark things apart.
