And do you know how our pets see this world when they look at us with their smart little eyes?

According to the research of scientists, it turns out that dogs have much worse vision than people, so they see everything as if in a fog. Dogs are born with blurred vision, that is, they see the world around them 8 times worse than us. In addition, dogs do not distinguish certain colors.

Here are some interesting facts about dog vision:

Do dogs distinguish colors?

Dogs have dichromatic vision, which means they only see blue and yellow

Previously, it was believed that dogs see the world in black and white. But scientists have proven that dogs see colors, although their vision is not as bright as that of humans. They distinguish between yellow and blue, but not red and green.

Dogs distinguish shades of gray better.

In the dark, dogs see 3-4 times better than humans. This is due to the better expansion of the pupils and the specific structure of the retina.

During the day, a dog's visual acuity is about three times less than that of a human. This is explained by the fact that the human eye has a so-called "yellow spot", which is not present in the dog's eye.

The dog sees moving objects better. She can see them at a distance of 800-900 m, and at a distance of 300 meters she may not notice a person standing still. That is why you cannot run away from a dog.

The dog determines the distance more accurately. However, at a distance of up to 35-50 cm, the dog sees blurry.

Sight.

The viewing angle of a person is about 180 degrees, for dogs it is 250-270 degrees, and it depends on the breed, the shape of the skull and nose. (For example, in a pug, Pekingese, English bulldog, i.e. breeds with a short nose and a wide muzzle, the eyes diverge at a relatively small angle and therefore side vision is limited).

Do dogs watch TV?

The frequency at which the human eye perceives a moving image is 50-60 hertz, in a dog - 80 hertz. Since televisions are designed for humans, the dog sees flashing images instead of a movie.

However, modern TVs have a frequency of 100 hertz, so you can watch movies with your loved ones.
