Amazing facts about the eyes of the pet that shares our home
You walk in the complete darkness and suddenly you find two bright eyes staring at you, it is your kind cat! Then you wonder: Why do cats' eyes light up in the dark? There is an amazing scientific answer to this question, as well as surprising facts about the eyes of this pet that shares our home.
Why do cats' eyes light up in the dark?
Cats 'eyes light up in the dark due to a layer or pigment called Tapetum Lucidum found on the retina of the eye, and the function of this basic layer is to exploit the little light in the surroundings to be able to see the surrounding shapes more clearly, and this layer acts as a reflector behind the retina of cats' eyes.
Therefore, when the cat is in a place with little light, the Tapetum Lucidum layer absorbs all the surrounding light, because it contains these light-sensitive cells, so the light is reflected on the retina, so that the cat can see better, while its eyes turn into bright eyes with the reflection of light, As explained by the US Indiana Public Media.
Not all animals' eyes glow the same color, and this is due to various factors, such as levels of riboflavin or zinc in the Tapetum Lucidum layer, as a veterinarian explained to the US National Public Radio website, and because there are varying amounts of dye inside the retina, this affects the color.
