Huge eyes of cats – a source of inspiration of artists, poets and photographers. It seems that such eyes are capable to make out anything. But what is seen by our fluffy fellows and whether the sight of the person differs from sight of a cat?
Do not see in the dark
Popular belief is the theory about night vision of cats. Actually these animals are really capable to be guided well in the twilight, but if there is no light at all, they will see nothing too. A secret in the special structure of a cat's eye. In an eye at mammals two views of photosensitive receptors are arranged: sticks and flasks. And if flasks are responsible for the clearness of objects and recognition of flowers, then sticks provide twilight sight. Cats of sticks have much more than flasks, these animals – night predators and acute eyesight in the twilight it is just necessary for them.As an additional bonus of a cat received other structure of so-called area of the best vision. If the person has it in the form of small deepening on a retina, then cats have much more and represents a disk. By the way, the well-known magic luminescence of a cat's eye – too the feature of the building providing additional sharpness of twilight sight. An eye of our cats is arranged so that light which is usually dissipating on a surface can catch and to direct it to a retina. It turns out that light kind of is reflected from eyes of a cat, giving her the chance to see more. Here because of these "retro-reflectors" of an eye also glow in the dark.
How well cats seeYou should not think that cat's sight – a standard. Contrary to popular belief, cats see not so sharply. They perfectly distinguish objects close, but what is remote from them on some distance, already seems them is indistinct. For the person it would be considered as visual impairment, but pets to see everything around in a long distance just do not have need. Being a predator, the cat has to manage to record the potential victim in the field of the attack. Besides during hunting and daily affairs the cat is guided more by hearing which at her is very sharply developed. When mice run in 20 meters from her, sense it is simple to watch them at a cat is not present. Other feature of sight also connected with hunting, best concentration on moving objects. It is impossible to tell that if something slowly moves, the cat of it will not notice, but it is the best of all for her those objects which move quicker will be visible.
Color sight
A human eye is capable to distinguish colors of a range, but representatives of fauna in the majority have no this feature. Dogs, for example, see everything monokhromno that to cats, they distinguish only some colors: shades gray, blue and yellow. And here red cats not to see capable.
