The reason why cats’ eyes are green when taking pictures:

The main reason is because the cat’s eyeball structure is quite special. When the light passes through the retina and reaches the back of the eyeball, The light reflected from the iris will still pass through the retina, which is why cat eyes glow when seen in low light. Many felines have many special lenses at the bottom of their eyes. , these lenses have a strong ability to gather light, and can gather the weak scattered light around them, aggregate it into a beam, and reflect it concentratedly. Animals with such glasses generally have a strong ability to move at night. They can rely on tiny The light is used to identify objects, and from the outside it seems like their eyes are glowing. This is why cats’ eyes appear green when taking pictures of them.

Trivia about cat eyes:

1. Cats’ field of view is 200°, while humans are 180°

2. Cats do not need Blinking regularly like we do, the way it looks at you so intently is, in fact, conducive to hunting.

3. Cats are not color blind. Cats can recognize red, blue and yellow light, and can also differentiate between red and green. The number of visual cells that cats use to perceive color is only 1/5 of humans, so what appears to be bright blue in the eyes of humans is a dull blue in the eyes of cats. In addition, cats lack the visual cells to detect red, so red looks more like gray to cats.

4. Cats only need 1/6 of the light required by humans, so cats can see things clearly in the dark. The cat's pupils will automatically adjust the light entering the eyes. If the light is dim, the cat's pupils will dilate wider to allow more light to enter the eyes. Therefore, the cat’s pupils will stand up under strong light at noon, and when the light is dim, the cat’s pupils will open into large circles. This is the best time to look good on the camera!

5. The colors of cats’ eyes are originally only yellow-green and gold. The amount of melanin determines the actual color of their eyes. However, after being raised and cultivated by humans, varieties lacking high melanin gradually appeared, and various variants also emerged. Newborn kittens have light-colored eyes due to the lack of melanin in their bodies. As they grow older, melanin slowly forms, and they will return to their original color within three or four months.
