Melanopsin

Alright kiddo, so basically melanopsin is something in our eyes that helps us see. Our eyes have special cells called "photoreceptors" that help us see light, and one of these photoreceptors is called melanopsin.

Now, melanopsin is pretty special because it helps our body know when it's daytime and when it's nighttime. It does this by sending signals to our brain that tell our body it's time to be awake or to go to sleep.

So, when we wake up in the morning and we see sunlight, the melanopsin in our eyes tells our brain to wake up and start the day. And then when it starts to get dark outside and we see less sunlight, the melanopsin tells our brain to start feeling sleepy and get ready for bed.

So, even though you might not see melanopsin directly, it's really important for helping us see and know when it's time to be awake or asleep!
