How Well Can Cats See in the Dark?

One afternoon my sons had loads of questions about cats, mainly how cats see and why cat eyes appear to glow in the dark. Why do cats’ eyes glow? Maybe you’re wondering, “Can cats see in the dark?”

Why not, right? Their eyes glow. It seems like a reasonable conclusion.

So I set off researching a science activity that would help us explore that concept. Sure enough, I found one in Janice VanCleave’s Big Book of Play and Find Out Science Projects.

Can Cats See in the Dark?

Not really is the short answer, but according to this article about how cats see the world compared to humans, cats do have superior night vision.

“Cats can’t see fine detail or rich color but have a superior ability to see in the dark because of the high number of rods in their retina that are sensitive to dim light.

As a result, cats can see using roughly one-sixth the amount of light that people need.”

How cool is that?

Science Behind Why Cats Eyes Glow

Cats appear to have glowing cat eyes because the back of their eyeballs includes a unique reflective surface called the tapetum lucidum.

Light comes into the eye, the light is supposed to hit the photoreceptor that transmits information to the brain.

When light doesn’t hit the photoreceptor, so the tapetum lucidum acts as a mirror and bounces the light back for another chance.
