Studies have shown that cats have better eyesight than humans in the dark. At night, cats can see more clearly than humans, and their night vision is generally several times that of humans. However, cats are actually nearsighted and can only see things clearly at close range.
However, dogs' vision is many times worse than humans'. At the same distance, humans can see objects very clearly, but dogs can only see the general shape and outline of things. In addition, dogs are colorblind. They were once thought to be black and white blind, but now research shows that they can see red and yellow colors in addition to black and white.
