How Cats and Dogs See the World: Interesting Facts
08.04.2024 17:45
Some time ago, it was believed that dogs saw the world in black and white, then violet. But recent studies seem to have put an end to the debate.
According to the latest data, dogs and cats, like many mammals, are colorblind.
Naked-science writes about the peculiarities of vision of beloved pets.
Just the facts
1. Mammals were originally nocturnal, so their vision did not develop enough to distinguish colors – it is useless at night.
Because of this, dogs and cats still have green and blue receptors.
2. The colors that dogs and cats can distinguish are more muted, but pets can see perfectly well in the dark.
It is not necessary to say at all that animals can distinguish shades.
3. And most mammals are farsighted. They don't really need to see well up close, thanks to their whiskers.
4. Perhaps the most interesting thing is that the vision of animals does not allow the formation of a clear image, and all because of the peculiarities of the structure of the eye.
Light in the eyes of dogs and cats passes through the retina twice, causing the image to fail to focus and appear blurry.
Conclusion
Based on the data obtained, scientists concluded that our pets do not see the world in all its usual beauty for humans.
But they don’t need this, and this deficiency is compensated by their excellent sense of touch, hearing and smell.
