There are few people in the world who would be indifferent to cats. These fluffy animals fascinate and fascinate us, and their eyes have a magical power. The eyes of the cat are very large, like all animals that are nocturnal. If our body and eye proportions were the same as those of our pets, we would have several times more eyes.
Vision of cats in the dark
In absolute darkness the cat does not see at all, but it is necessary to appear a small ray of light, as it turns into an unsurpassed night hunter, although it sees at night everything in black and white. It should be said that with increasing brightness of light, cat's sight, in contrast to dogs , becomes worse. For normal life, our pets need 6 times less light than us.
It is interesting that the behavior of blind cats is not much different from normal. The lack of vision is successfully compensated by the aggravation of other feelings, such as sense of smell and touch. The length of the mustache in such cats is one-third greater than it should be.
Our eyes, unlike the eyes of a cat, have a yellow spot, to which the whole stream of light comes and on which the perception of the surrounding world depends, including visual acuity and brightness of colors. In cats, the yellow spot is absent, and the retina of their eyes is divided into two parts. Its upper part is responsible for the vision in the dark. The magical green color of the cat's eyes at night is nothing more than the reflection of the upper part of the retina. The absence of a yellow spot affects the visual acuity. But the cats do not watch TV and do not read the literature, and it will not be difficult to catch the mouse on its contours. A person better perceives objects that move slowly, but the cat on the contrary. She has a quick reaction from the hunter, although she does not see well under her nose. The best distance from which the cat sees is 0.75 - 6 m.
For many years, disputes were being waged as cat eyes see. People thought for a long time that cats only have black and white eyesight.
If you have a cat, pay attention to her eyes, rinse them, prevent various diseases . She will thank you with her affection.
