The cat is one of the most popular types of pets. Despite this, until now, not much was known about the peculiarities of feline anatomy and, in particular, vision. Most ordinary people still have outdated ideas about their smaller brothers. It is generally accepted that cats cannot see flowers and are relatively helpless during the daytime. In reality, things are a little different.
Instructions
Step 1
Let go of the prejudice that cats have black and white vision. Until recently, it was believed that felines have monochrome vision, but in fact, they distinguish between several chromatic colors (just worse than humans) and more than twenty shades of gray.
Step 2
Cats are really much better at navigating in the dark. This is due to a special reflective layer of the retina of their eyes, which is called "tapetum" (ancient Greek. "Veil"). This layer doubles the perceived photon of light and allows you to see better.
Step 3
Pay attention to how the cats behave while playing. They react to the horizontal movement of the toy more actively than to the vertical one. This is due to hunting instincts: mice and rats move in a horizontal plane, therefore, as a result of evolution, after centuries of tracking down prey, cats have developed a specific feature of vision, it is easier for them to focus on an object moving horizontally.
Step 4
Cats have stereoscopic, panoramic vision. Their eyes are close together, looking forward. The resulting binocular vision effect allows the cat to form an accurate picture of the environment and accurately calculate the location of the victim.
But there is also a significant disadvantage: to see an object on the periphery, you have to turn your head. In addition, cats are nearsighted, objects in the distance appear to them as vague silhouettes.
Step 5
Cats need eyelids to protect the mucous membranes of the eyes and regulate the light entering them. Unlike humans, cats have a third, lateral eyelid that distributes tear fluid over the surface of the eyes. A characteristic feature of the structure of the cat's eyes is the presence of more light-sensing cells than even some primates. They also have more neurons in the visual processing centers in the brain.
