Question

Why do cat's eyes glow at night?

Answer 1

Tapetum lucidum:

1. The cat's eyes light at night because of the presence of tapetum lucidum.
2. Tapetum lucidum is a membrane layer that is frequently seen in the eyes of mammals and is found in the eyes of both vertebrate and invertebrate species.
3. The tapetum lucidum, a reflective surface, gives the animals' eyes the appearance of gleaming in the dark.
4. Tapetum lucidum is absent in human eyes.
5. Behind the retina, this is placed. The light beams bounce off the membrane as they enter the eye.
6. Animals' "eyeshine" is a characteristic caused by the presence of tapetum lucidum.
