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. It takes 8 or 10 days to open them and when they finally do, they lack visual capability , they are blind, and they have to wait 24 hours for their eyesight to begin to develop. During the first few weeks the eyes are blue, they do not focus or distinguish anything, but gradually their eyesight improves until, after a month or two, they acquire total visual capacity. At 3-4 months your eyes will get their final color.
Cats used to be seen in black and white, but some studies have shown thatcats identify colours, although limited and depending on the amount of light in the environment. Color perception is determined byphotoreceptorslocated in the retina, called cones. Humans have3 different types of conesthat absorb red, green and blue light. Cats, on the other hand, only have cones sensitive to green and blue, but not to red. Therefore, although they are able to distinguish hot colors from cold ones, they only see cold colors,red ones see dark gray color.
Light also influences the way cats perceive colors, the less light there is, the less their ability to distinguish them, soat night they see black and white. However, this does not prevent them from having excellent night vision. Their night hunter eyes have adapted to the dark, they have a structure under the retina that works like a mirror, intensifying their vision. It is this structure that makes your eyes shine when they look at an 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 eyes on 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.
