Macro Pupil Constricting in Slow Motion – The Slow Mo Guys
Macro Pupil Constricting in Slow Motion – The Slow Mo Guys
British people are not known for great eye contact, but Gav steps up his game by looking deeply into Dan’s eyes… From about 2 millimeters away to find out how quickly a pupil constricts.

The Speed of Pupil Dilation – The Slow Mo Guys
Filmed at 1000fps and 500fps with a Phantom Flex 4K
You should do axe and knife throwing slow motion and explain the physics of it if you can!
and they know a certain Mad King that can do the throwing for them
This needs to be seen…it would be so cool as it split the wood
Doctors would probably not recommend shining that bright light straight into one’s eyes, but this is gave and dan we are talking about…
Actually many lights that are used by Dr’s are brighter than this light… It is the UVA and UVB rays that can cause damage not just straight light…
+Jessica Blackwood So how would you know if it was damaging or not? asking because I did this accidentally recently with my phone’s flash
You’d need light on the scale of the sun to do damage, luckily this LED isn’t close to that 😀
But you are correct, you need to be carefull with your eyes. They are very sensitive and are known for poor healing after a certain amount of damage. Plus you need both of them
+tom selier I looked at the sunset a couple (4-5) times over the summer, I never looked more than 2/3rds of a second, it was just my curiosity got the better of me. I imagine I caused some damage
nothing like shoving a gun barrel directly into your eye…
Yes, yes. It’s a camera lens. But still. Just look at it. XD
Dan twerking his eye-booty
Just no.
How this is not top comment?
Nooo not mine, your comment is awesome, you should be top comment on the video.
I can also do this
Anyone else’s eyes water at the beginning? 1:25
You should put like a back massager against your head near your eye and see what that looks like.
Definently an interesting idea!
Yes that’s a amazing request
Press F for Dan’s vision
FFFFFFFFFFFFFFFFFFFFFFFFFFFFF

?There are other slow mo probing uses for this lens ?.
Guys, we found GAVIN!
GAVIN
Hhhahah
SCE IF ohh Gav…I’m so worried
SCE IF you sir, win YouTube for the day
Wha
Well now i kinda want to watch everything up close, on with that fellas 😛
Do a toad eating a bug in slow mo
Ben’s Channel 2004 check out @smartereveryday. They did it with a chameleon and crickets!
+nick91793 I actually did it but it was only 240fps
Or you can’t just watch animal planet to see the same thing…
Do a bug eating a toad in slo mo
eww
pluck out eyelashes in macro
I’ll never see my eyes the same way…
Oh wait I can’t see my eyes 🙂
Ever heard about mirrors?

-Ever heard about mirrors?-
Ever heard about cameras?
My youngest sister had her eye scratched when she was really little (like 5 years old or so). It was a long, jagged, diagonal scratch across her cornea (the clear lens on your eye). We took her to our eye doctor (he’s incredibly good) and he took a close-up picture of the scratched eye. Then he prescribed a special antibiotic lotion that we had to put in her eye (it was specifically an eye lotion). After a week, we took her back in to get her checked out. He took another close-up picture of her eye. I was able to see the before and after pictures, was able to see that the scratch had healed completely, and had a brief conversation about why the scratch was dangerous: it can get infected.
Jagged wounds in the cornea can allow bacteria to take hold and start to eat at the rest of the lens, which is why it was important to use the special antibiotic lotion. The lotion itself also lubricated her cornea to prevent the wound from being torn open further by the action of her blinking eyelid.
The reason I’m even sharing this story is because it was the last time I saw an eye up close and magnified.
Nym Alous it was an interesting story thank you for sharing it 🙂
Nobody cares
+Laygónian 489
No. You don’t care. You can’t speak for anyone else. Because I do… In a I find it fascinating sense.
+Ethan Gray ur wrong
There isn’t much of a point in saying “nobody cares” if somebody does care, it might as well be a way to say you don’t care, just another way of being rude.
you should’ve tilted your head and capture the Vestibulo-ocular reflex, when the eye basically maintains its orientation to keep the image stable, pretty cool plus its the fastest reflex in our body!
Um I’ve never heard of that. What exactly happens, and what would you expect to see? The actual eye itself somehow counters tilting??
Pirosbor If you look at something and move your head but continue to look at it you will get this affect
The best way to see that is to look at your eye in the mirror and then tilt your head from side to side. A bit like a dog does when it hears a strange sound. You will see your eyeball stabilize and try and stay level with the floor. Within limits of course.
+seibernator im imagining a free floating eyeball travelling through your brain as you do a corkscrew
The camera looks like some sort of weapon
agreed
Those cool little craters in your iris are called Crypts of Fuchs. They let the deeper part of your iris enjoy the clear goop above them.
That is super neat. I probably won’t retain this knowledge but it’s fun to know either way.
It disturbs me that you used the word enjoy.
Another fine name for a heavy metal band!
how many fingers am I holding up?
“One donut”
My eyes won’t stop watering…
*…MY EYES…*
This is funny and breathtaking at the same time.
