Why Do Cat Eyes Glow in the Dark?

The video explains why some animals' eyes glow at night due to a structure called the tapetum lucidum, which reflects light back through the retina, enhancing night vision. It describes the basic eye structure, including the retina and optic nerve, and how the tapetum lucidum functions like a mirror. The video also covers how different animals have varying eye shine colors based on the materials in their tapetum lucidum, such as guanine, collagen, and riboflavin.
