My eyes in the mirror—there's something there
While looking in the mirror, Didi discovered a mysterious pattern inside her own eyes.
Dive right into the AR eyes in WAGZAK JUMP, tap on the cornea, lens, and retina one by one, and uncover the secret of how light travels inside the eye.
From experiments on how the pupil expands and contracts to the principles behind eyeglasses—join Dee Dee as we take a closer look at how our eyes see the world.
What’s inside my eyes in the mirror?
I stopped while looking in the mirror.
I stood in front of the mirror to brush my teeth, and there was something inside my pupil. A tiny dot? No, a pattern? It looked like brown stripes spinning around and around. What is it?! What on earth is this?!
I held my breath and stared at it for a long time.
I asked Popo, and this is what he said: “That’s called the iris. You have your own unique pattern.” My own pattern? Like a fingerprint? Hehe, that’s kind of cool, isn’t it?
But then Popo told me to open the JUMP app, so I did, and... Eek! There was an eyeball floating right in the middle of my room! A real eyeball! It had this clear, jelly-like stuff inside, and you could even see the blood vessels on the surface. It was a little scary at first, but when I tapped it, the names of each part popped up.
Cornea, tap! Lens, tap! Retina, tap!
The cornea is like a transparent window at the very front of the eye. When I swiped my finger, the lens popped up—it looks really fascinating. A jelly lens? It kind of looks like a convex candy. Behind that is the retina, which looks like a movie theater screen; that’s where it captures light.
It took me a while to tap on all of them. I had no idea there were so many parts inside a single eye.
Does the light get flipped upside down inside the eye?
That’s what Popo said. “Light goes on a journey inside the eye.”
A journey? Light?
The app showed me—a beam of light actually shoots right into the cornea and bends as it passes through the lens. Just like how a straw looks bent when you put it in water! Then it goes *thud!* and hits the retina.
What?! The world is upside down!!
The trees are growing upside down. The sky is below, and the ground is above. I was totally flustered and asked, “So are we looking at things upside down right now?!” Popo laughed and explained that the brain flips it back.
The brain!
The brain quickly corrects the upside-down image that the eyes receive. Apparently, our brains are doing that every single moment. Even right now. I thought I was just looking, but my eyes and brain were working together. Hehe, there was teamwork going on inside my body.
Do your pupils really get really big in the dark?
I said to Banggu, “Hey, let’s try this together!”
I turned off the lights. I looked in the mirror in the dark. After about 30 seconds, I shone my phone light on the mirror.
Eek! My pupils were really dilated!!
