How do cats see?

The vision of cats is different from ours. Do you want to know how cats see and their vision capabilities different from those of humans?

Cats are born with their eyes closed. They take  8 or 10 days to open them  and when they finally do  not have visual capacity  , they are blind, and have to wait 24 hours for their eyesight to begin to develop. During the first weeks the eyes are blue, do not focus or distinguish anything, but gradually their eyesight improves until, after a month or two,  they acquire total visual ability . At 3-4 months your eyes will get their definitive color.

Earlier, cats were thought to see black and white, but some studies have shown that felines identify colors , albeit limited and depending on the amount of light in the environment. The perception of colors is determined by photoreceptors located in the retina, called cones. Humans have 3 different types of cones that absorb red, green and blue light. Cats, on the other hand, only have cones sensitive to green and blue, but not red. That is why, although they are able to distinguish hot from cold colors, they only see the cold ones, red see it dark gray .

Light also influences the way cats have to perceive colors, the less light there is, the less their ability to distinguish them, so at night they see black and white . However, this does not prevent them from their night vision from being excellent. His night hunter eyes have adapted to darkness, they have a structure under the retina that functions like a mirror, intensifying their vision. This structure is what makes your eyes shine when they look at intense light while in darkness, for example, the flash of a camera.

On the other hand, cats have  less visual acuity than  people, that is, they do not focus equally well on objects, and they are also a little short-sighted. However, having the eyes in the front of the face like humans, they have  binocular vision  and can encompass their field of vision simultaneously with both eyes. This quality allows them to easily and accurately measure distances.
