Video: The ability to see between people and animals

Because the eye structure is very different from humans, the images of the world around them in the eyes of animals are not the same as what we see.

For example, dogs only see things in shades of brown, yellow and blue. They have a wide range of peripheral observations.

Cat eyes have more inner eyelids to protect, but they only observe the world around them in colors like dogs.

Birds can see ultraviolet light, while humans do not have this ability. The bird's eye muscles also focus on certain positions in the scene.

The flies are made up of thousands of tiny crystals, making them able to see ultraviolet light like birds. However, flies look at every movement like through a slow-motion lens.

Snakes possess quite special eyes. At night, they can see heat signs that help reveal your goals. Meanwhile, sharks possess eyes that clearly see underwater, but they are "color blind".

Goldfish can see objects in red, green and blue. Their eyes also have receptors for the color of ultraviolet color.

For mice, each rodent's eye works independently. They look at everything, the phenomenon in a "slow-motion" state , blurry and unclear. The mouse does not look red.
