Cats have little difference in shape compared with human eyes. But the world that cats see is a lot different from what humans see. They see the world like the world through the filters of human beings, very vague, but also very warm ...

Nickolay Lamm, an artist Nicreleme, has largely restored the images seen by cats by collaborating with animal eye clinics and animal eye doctors. As can be seen from Lyme's image, although the cat's vision is vague, they can see nearly 200 degrees of view, while humans can only see a 180-degree plane view.

In addition, cats can have around 30 degrees of peripheral vision, while humans have only 20 degrees of peripheral vision. These differences between cats and humans are mainly due to their evolutionary process in order to accommodate the need to prey at night. In dark Light, the cat's eye is 6-8 times better than human vision.

Finally, the cat can see the color is also limited, mainly can see yellow and blue. This allows it to omit the complex colors in the background and can quickly lock the target.

The blurred area of the top edge of the picture represents the perimeter view, which is 20 degrees in humans (pictured above), and the cat is 30 degrees.

Cats cannot focus clearly on objects beyond 20 feet (about 6.1 meters). Nicolas Ram considered the workings of the cat's eye and drew on the advice of veterinarians and eye experts to produce pictures of the world in the peephole.

Cat color vision is significantly inferior to humans, which is related to the different densities of photoreceptor cells on their retina. Scientists used to think that cats are two-color--they can only see both colors--but they are not.

The cat's vision can expand to 200 degrees, while humans are only 180 degrees. Although cats have a wider vision than humans, their visual acuity is not high. We can clearly see objects 30 to 60 meters away, but for cats, more than 6 meters of objects will appear blurred.

The sight of Shanghai in the cat's eye. The cat's sense of color is different from ours, and that's why these pictures don't look as colorful as the human vision. The photoreceptor cells of cats are most sensitive to the wavelength regions of blue-violet light and yellowish-green light, so they may be able to see some green. In other words, cats are mostly red-green-blind and, like humans, they can see a little bit of green.

Cats are particularly good at capturing fast motion in addition to the low-light vision that is better than humans. The cell reacts faster, allowing the cat to capture very fast motion pictures, such as the path where the laser dots move quickly.
