How Night Vision Really Works And Why Humans Don’t Glow at Night?
Night vision is often shown as glowing eyes in movies. In reality, it works very differently. This comic explains how human and cat eyes behave in low light and why seeing at night has nothing to do with glowing.
As light fades, human eyes rely more on cells that detect brightness and movement, not colour.
Cats have a reflective layer that helps reuse light, making them better at seeing in darkness.
The comic walks through this idea step by step in a visual, easy-to-understand way.
