X 9th Grade CommonlLit Reading Assessment In this article, Braidee Foote explores why cats' eyes glow in the dark. [1] Cats and many other animals, including most dogs, can reflect light from their eyes. That's why cats' eyes will usually shine brightly in photos taken in a dimly lit room or glow when illuminated in the dark by flashlight or a car's headlights. Species whose eyes glow have changed over time to see better in low light because they either forage for food or need to look out for predators throughout the night, or they do most of their hunting at dawn and dusk. In fact, domesticated cats can see in conditions that are only 16% as bright as what people require. Cats accomplish this because their pupils the openings that appear black in the middle of their eyes are special. Pupils operate like windows, with bigger ones letting more light into the eye. And a cat's pupils can become up to 50% larger than human pupils in dim light. They also have a higher number of a specific type of light-sensing cell in the back of their eyes than we do. These cells, called rods, catch low-level light.
