Animals with night vision

Let's look at the example of a cat device eye, seeing in the dark animals. If you look deep into her pupil, you can easily see the silvery layer of crystals. They look like a mirror. It is they who enhance the light that enters the eyes. Because of this, cats can see perfectly in the dark. But the daylight is too bright for the cat's eyes. Therefore, in order to defend against it, she has to “squint”: in the afternoon, the cat looks with pupils-lye.
Geckos protect their eyes just like cats. At night, they look at the world around them with large, black, round pupils, and during the day their pupils become narrow.
