Dog owners often wonder how their pets see the world. Human and dog eyes are arranged differently, and what we see is very different from what they see.
British veterinarian Ryan Rochford decided to show how pets see the world. To do this, she created a series of photographs of popular tourist destinations in the UK. Some show how a person perceives them, while others show how dogs do it.
The eyes of dogs are located at an angle of 20 degrees. This increases their peripheral vision, but also means that their binocular vision is less developed.
In human eyes there are photoreceptors that react to light, and there are photoreceptors that are responsible for color differences, and they are called cones. Dogs have two of these cones, and humans have three. Therefore, the perception of colors in dogs is different.
According to the veterinarian, dogs, due to the special location of their eyes, have better peripheral vision, that is, they see better than a person what is happening outside the center of attention. But among the disadvantages of vision in dogs, Rochmond calls the fact that pets do not see objects three-dimensional, which reduces the level of perception of the depth and volume of the visible object, as well as the distance to it.
But dogs do not particularly suffer from the fact that their eyesight is worse than that of humans. They rely more on their sense of smell in their daily lives. According to scientists, it is 10-100 thousand times stronger in dogs than in humans. Therefore, when a dog loses his sight with age, he can still live normally.
