You may have heard people say that cats can see in total darkness. Is that possible?

(a) Yes, they send rays out of their eyes that enable them to see in the dark.

(b) Yes, they see in the dark, although no one knows how they do it.

(c) Don't be ridiculous. Vision is the detection of light, so vision in darkness is impossible.

Explanation

Not exactly. Where it's been widely thought that cat's have their own built-in set of night vision goggles, they actually require at least some level of light to see. However, they only need one-sixth of the amount of light that humans do and can see in very low light.

 

They have 6 to 8 times more rods than the human eye, giving cats the ability to see well in dim light and the ability to detect motion more accurately in the dark. Cats are nearsighted which means that what people can see clearly as far as 100 to 200 feet away, cats can only clearly see less than 20 feet away.
