How Does Phototransduction: How we see photons Work?

We see because special cells in our eyes turn light into messages that our brain can understand.

Imagine you're playing with a flashlight at night. When you switch it on, light, which is made of tiny particles called photons, goes flying out and hits your eye. Inside your eye are little helpers called photoreceptor cells, like mini detectives waiting to catch the photons.

These photoreceptor cells have special tools called pigments that react when they meet a photon, kind of like how paper turns dark when you color on it. When a photon hits the pigment, it starts a chain reaction inside the cell, like knocking over a line of dominoes.

This reaction sends an electric signal down a nerve to your brain, telling it something about the light, was it bright? Was it red or blue? Your brain then turns that information into what you see, just like how you can tell the difference between a toy car and a teddy bear by looking at them.

So every time you see something, it's because photons are having an exciting little party in your eye, and your brain is listening in!
