What are rod and cone cells?

Your eyes have tiny little helpers called rod and cone cells, which help you see things clearly, just like how your brain helps you solve a puzzle!

What do rod cells do?

Imagine you're playing hide-and-seek in a dark room. You can still see shapes, but not colors. That's what rod cells are like! They’re the detective helpers that help you see in low light, like when it’s nighttime or inside a cave. Rods are good at catching motion and giving you a black-and-white view of the world.

What do cone cells do?

Now imagine you're looking at a rainbow. You can tell all the different colors, red, blue, green! That's where cone cells come in. They’re like color experts, helping you see bright colors clearly. Cones are especially strong when there’s lots of light, like during the day.

So together, rods and cones work like a team to help your eyes do their best job, seeing everything from shadows to bright colors!
