I will quote my answer to the question about the glowing eyes of cats, it will be clear how this is related:

_ _ _ __

In cats, as well as in some other nocturnal animals, the eyes do not glow, and under certain conditions they reflect light.

Most often this can be seen in photographs. In other conditions, it is theoretically possible to see this, but it is very unlikely.

If you have been photographing for a relatively long time, you must remember that there was a so-called red-eye effect in the case of photographs of people with flash.

This was due to the fact that the bright light from the flash passes through the opening of the pupil and illuminates the numerous blood vessels.

And what about cats?

They are night hunters and it is important for them night vision. To improve it, cats and some other animals have an interesting device. Mirror layer of the eye shell! It gives light an additional chance to react with receptors. Wiki

This is the layer that perfectly reflects the camera flash and even other light sources and gives the effect of glowing eyes.

Now I will tell you one thing that will change your world forever. Ready? Well, cats can't see in the dark! Due to the structural features of the cones, they are able to see more clearly at dusk, but in the dark, cats are guided by whiskers (vibrissae) and smells. But this is an approximate data, the cat will not rush headlong in the dark. The only natural way to see, in complete darkness, is ultrasound (like dolphins and bats).

But since you are a human, and all the technical advantages of an intelligent creature are available to you, you can buy a night vision device and be happy that now you can see better than any cat in the dark.

I must admit that not a single cat willingly will agree to give up its eyes for a transplant. And there is no other way. The fact is that there are two types of visual formations in the retina of the human eye. Some, called cones, perceive the shape and color of objects. Others, rods, also called twilight vision apparatus, distinguish between light and shadow. So, the sticks contain visual purple (rhodopsin), which decomposes in the light. As soon as we are enveloped in darkness, rhodopsin begins to accumulate and increases the light sensitivity of the eye. The retina of nocturnal mammals (cats are just such) consists mainly of rods, while daytime animals (like humans) are made up of cones. It is impossible to change the ratio of rods to cones in the human retina. If the supernatural abilities of a cat make someone jealous, incompatible with life, try eating carrots. The carotene it contains improves night vision by influencing the rate of rhodopsin production. After a carrot diet, you can probably learn to find a black cat in a dark room, even if it is not there.
