voluntary pupil dilation

[nightshadewolf01]

i can shrink my pupils...everything spilts into 2 and at the same time it's blurry, its, weirdly, fun!

[sibyunni]

unfortunately I do.

[sibyunni]

so you are Holding your breath? hahaaha. Sympathetic system Dilates your eye. When you are holding your breath, CO2 concentration in the body increases, so I made a quick google search and found this "For example, increased blood concentrations of carbon dioxide will cause stimulation of the sympathetic nervous system"

[alligatorrPENS]

@sibyunni Sympathetic system? You sure that exists, mate?

[sibyunni]

@alligatorrPENS



[starfire56500]

omg. on videos like this i always skip to the end to see if there are any scary faces!!!

[alligatorrPENS]

@TylerTheLaosKid You musta smoked a loottt of weed...

[TylerTheLaosKid]

@alligatorrPENS i don't even remember.

[SmilieOwlie]

OMG!

[hVL94]

@TylerTheLaosKid chill out mate

[Windwolfdog]

How do u flip the switch on bruh

[sealygirl123]

Peering into my soul... O.o lol

[vladiskvortsova]

Hi my name is Vlada and i can do this non stop. The fucking electrical feeling is always in my legs and its driving me crazy sometimes i cant even sleep. ive asked doctors and no one knows what to do. do you have problems with it? I've woken up twice with the electric feeling and felt it happening and my whole body started having spasms. I felt like i was having some epileptic attack or something, although i don't have epilepsy.

[SilentlySearching]

@vladiskvortsova It is most likely a form of tics which is a form of tourettes my sister has the same thing and she cant control it and it's involuntary u should see ur docter about it

[morv1891]

@vladiskvortsova I had this when I was a kid... I think it'll go away just don't think about it

[irvykinneas]

IT'S ALIVE

[nabnabnabn]

dude i have the same ability!

[Muz33kful]

Well that suck, cuz I have dark brown eyes. Theres really no point

[WhoAr3You]

Ive learned how to do that automatically after smoking pot a couple times.I noticed my pupils would dilate every time I got stoned and observed them in the mirror.My eyes felt different as well and now I can do it without being high.Its like turning on a switch in my brain to feel that same relaxation on the eyes that pot has taught me to experience.Its somewhat like a learned experience I guess

[f1tch]

bumbles

[jveteran]

This is fantastic. I'm writing a book about this. Our pupil dilation is tied right into our sanity and our ability to replenish our Cerebral Spinal Fluid.

[AustinSalgat]

Great to finally see other people who can do this! You're right about that adrenaline feeling. I know of several people who use an emotional or some other type of trigger to dilate their eyes but never someone who could just do it. I'm not sure sure about the "3rd eye" explanations but it is cool to find others with this quirk :)

[B1CYCL3B43ST]

this happens when i abuse my aderralll

[personlalafa]

:O I can do that!! The electricity is based around my sacral chakra... and then kind of goes everywhere. And If I don't control it... My body starts to shake.

[seanutbrittles]

I THOUGHT I WAS THE ONLY ONE WHO COULD DO THAT LOL. But mine's not as noticable as yours cause mine are dark brown

[rooroo1988]

I did this once and it freaked my girlfriend out.

[jmacalangi]

My eyes a fkin black... lol

[sheilaonlineDOC]

I am able to do the same thing while experiencing the same feeling you explained in the end of the video. Please contact me through Faebook. Sheila Harding Oceaside CA Mira Costa college. unless there is a way to write mail through Youtube. I am new with my account.

[elronman]

look at magic eye books for years as a child, get the same effects.

[buddhistgangstamonk]

oh yeah, when i sniff the coco voluntarily it dilates the pupil =p

[mav3rick07]

I can control my eye muscle for this too, it feels like Im pulling a string behind my eye and light leaves and things get blurry. Once I want to restore my vision it simply just feels like I let the rope go that I was pulling on and things become bright and clear again.

[pogde5]

@mav3rick07

Thats what i can do aswell (:

[prisci247]

mine are dialated right now its been 9 hours and its still like this >.<

[delphiillumina]

very useful for my studies. the dude is weird, but the dilation part i needed, so thanx :)

[Nicro327]

It looks like a never ending anus, lol jk.

[Sponksponksponk]

he is attracted to the light!!!!

[HolyDragon07]

I can actually voluntarily contract them. but i cant dialate them.

[stormlord619]

Lol I can do this it makes me really hot like instantly sweating XP and twitch takes some real concentration to do I remember going to the doctors when I was younger and him saying I could mess up the heart rate test or something as my heart beat kept changing :P

[DubstepSwag]

I have been doing this since I was a wee lad, it is a big difference when I hit this and my anger switches at the same time. I know it gives me a powerful burst of energy which I use when I am training, or fighting. This kind of stuff is very interesting to me and I like to conduct my own little experiments too :]

[Xero3g]

galvanic response eh? I'm doing it right now, had no idea it dilated my pupils

[dymondgeezer2003]

when i do it i get a wierd rushing feeling down my legs. Even more strangely, i've been on prozac for maybe 2 months now and this feeling in my legs is constant and doesnt go away :S:S:S

[DarkRave36]

Aparently looking at someone you love or hate causes them to dilate

[EwwMandyWtf]

I always wondered what that rush was. So its adrenalin? When i do it for too long, i get really tired and out of breath even if im just sitting there lol

[Nicro327]

@EwwMandyWtf No it's just shock. If you could trigger adrenaline you would be able to move cars around, even if you weren't ripped at all. So yeah I don't think it was adrenaline.

[thecreaturebyhabit]

u got shit twisted, the pineal gland, third eye, and 6th chakra are 3 different things that are very close to each other

[MantechUK]

No way I can do it too! On my first attempt. Got a vid of it aswell.

Is it useful for anything? I know voluntary pupil contraction is useful for seeing underwater without goggles but I have no idea how to do it. If anyone does, tell me how please!!!

[itachiwalksalone]

the reason why having a rush of adrenline causes your eyes to dilate is because the adrenline causes your heart to beat faster and causes your pupils to dilate so you can 'better see' why you are having a rush of adrenaline. the same thing when you hear someone call out 'LOOKOUT' or something to you or aorund you. your pupils dilate so you can see the reason why the person said look out.

[78646666668]

dude finally i find someone who can do this

i can do this to is a shot of adrenaline sent to your body

raises your heard rate and does something to your muscle

[UnfairDinkum]

I can just sort of "flex" mine to get them to dilate. I don't know how else to describe it. I don't really do anything with adrenaline or anything, but I can... "feel" whatever controls it and I just sort of... flex it and they dilate. Kinda hurts a little, though, if I do it too much or too hard.

[freshburritos]

hey u know another way- crack!!! btw i dont do crack

[Jorjeca]

focus time '-'. Do you have a chill when you do this?

[darkloid0]

conditional reflex??!!

[Queuex]

if you can do this, can you see better in the dark?

[tubbykat1997]

I watched this then i did it and my mom witnesed it she asked me what i was thinking about i said punching someone out

Thanks for making the viedo

[johnnycrit]

I can do this really well. I've been doing this for 20+years but I only tonight decided to look at my eyes while doing it. It kinda freaked me out because I can make my iris pretty much disappear. When I do it, it's a really intense feeling waving through my body. I'm glad to see I'm not the only one.

[afroninjadeluxe]

@johnnycrit

WTF. I just did this while brushing my teeth and freaked out. Then i googled it and it feels good that im not alone. XD

[escottproductions]

@johnnycrit i can also do the adrenaline thing an thort i was the only one also i only just realized that it dialates the pupils.

[KillerGuitar007]

I really want to do this. I have a really freeky smile (volintary) so being able to dilate my pupils will make me looking like a evil crazy anime character :P

[mileysmiles111]

hahaha

[Beanzear]

I can do it, it's hard to sustain for more than 20 seconds or so. If you make a point to do it regularly, you increase how long you can hold it. When i do it while meditating, concentrate on the Pineal Glad - I see a point of light that begins to expand - that's about the tine when I can no longer hold it and it goes away. Not sure what it all means - but a strange thing indeed.

[combomaster99]

eyeBALL

[quest8899]

You should make some more videos dude

[neopetguy]

This guys kind of a creeper

[sjennings1990]

I can do it too. I used a heartrate machine thing to show my heart speeding up as well. Loads of people are trying to explain it and say its not possible or its a trick.....its is real. Its like tensing a muscle, i dont need to think about anything in particular or any scenarios...i just do it, its like tensing somewhere in your stomach/chest. My pupils just fly open and i feel my heart racing and beet really hard. Maybe all can do it, just practice..

[ChiliWilly16]

no fun, my eyes are too dark

[LewisEvn]

i can do it too, but i havent recorded my eyes to see if they dilate.

[96Nathan96]

I HAVE TO HAVE DILATED PUPILS If I get them all my wishes will come true

[BigDITKA11]

He took Molly 2 seconds before recording

[AngelStar188]

woah weird O___O

[Toadsanime]

Huh, weird. I could always do that tingly adrenaline thing, but I never really knew how to explain it. I wasn't aware it dilated my eyes though until doing it in the mirror just now.

[Krowsnose]

This is easy, he just has a porn picture he unminimizes to get the desired effect.

[C3vans]

This could be a really good screamer video...

[Alfourthousand]

Yeah i can do this. When i read you description i was like OMG thats exactly what its like!! the arousal in your body causes noradrenaline to dilate your pupil. I think thats right

[claudio990]

Cool Video (:

[forresn]

i know exactly what you mean by chemical switch as well.

i believe i do it alot unconsciously alot when im talking..

i notice peoples eyes dilate with mine when we are talking.

it is kind of wierd i have this odd control over my blood.

i think im pushing bood in a way that is able to make my eye dilate.

i can stop my heart and slow it and wierd stuff like that..

im sure it all has the same reason.

[forresn]

yeah i can do this..

[Fireballts11]

i can do it

[poopgetz]

how do you DILATE them? I can only make them pinpoint small, I can't make them bigger. anger!

[HiveMindAlpha]

You have learned how to flip the amygdala switch. The amygdala is between the back of your eye and your ear, just behind your temple and a bit above. This is the 'switch' that makes this possible. This is what gets messed up with people with panic, and by learning to control that switch you can resolve panic disorder immediately. It is a cool trick but it also has usefulness.

[cmccerg]

i too can dilate my pupils, release adrenaline, and alter my heart rate at will.

[jedidude04]

I can dilate both my pupils and always wondered why no one else could..

[tonychoitellem]

its easy as fuck juz go smoke some crystals if u wanna c pupils dilate

[Options5000]

I heard that you can pupil dilates when you look at something you want...

[flyassasin1]

just think of something that turns u on is the easiest way

[Nunchukawaria]

Yeah I can too. My cat does it back to me.

[FAE4CDF]

omg thats so cool and creepy i want to know how to do it

[anapirosk]

Yeah watchin porn to dialate ur pupil is cool

[Ev3rFl0w]

Can you see far distance or more detail on something when u do that?

[na6drifter]

I learned how to do this in the 4th grade, i would use it while playing soccer to give myself a rush before a sprint. the more you use it the better you get at it and pretty soon you can do it in a second without even trying but if you hold it to long you will feel on edge and and you will get intense chest pains.

[quest8899]

Physiological anomily

[diablotrackrunner350]

how do you do it

[veggiedisease123]

The gland is over your kidney. And i can do it.

[jennet4444]

Beautiful eyes !

[demondestroyer1000]

damn thats crazy dude,I wonder how big they would get if you were on shrooms.you should do it and make another post of it.

[Dreadnought942]

its kind of easy.

i can give myself goosebumps or adrenaline rushes.

you just forcus on something scary or imagine that somethings gonna kill you and youll feel it

[ElFuego121]

i can do this too. It started from just remembering my ecstasy highs. I think its just giving yourself adrenaline rushes.

[elitefitness84]

I can do this too. When I was in 4th grade I learned I could send an electrical feeling through my body at will. I cannot explain how I do it, I just can. Also I learned that when I do it, my heart jumps from around 75 bpm to about 150-160 bpm. It is also a very good feeling but can only hold it for about 6-7 seconds. I have shown people in the medical industry this and the are always very, very amazed. I'm gla I'm not the only one out there with this ability.

[TheAlexandre11]

@elitefitness84 4th grade in what discipline...??? 0_o

[feebunnylovesya]

O_O I CAN'T DO IT.

I have been practicing forever, but I still can't.

And my parents think I'm really weird now.

[SANTANAFACTOR]

:) this happened when I popped those two e tabs back in September even though both pupils were different sizes lmao

[mercythekitty]

Wow, I'm working on being able to do this-- never tried in a mirror, so I don't know if it's working or not. XD

That's soooome camera you got there... And I'm almost a little scared by how much your pupils dilated! Coolio. :3

[Nicro327]

I've been able to do this since I was 5 or 6. And when you do this, are you pumping adrenaline?

[necromatter]

I've been able to do this my entire life but also never met anyone else who could nor figured out what it was. Hard to describe how it's triggered.. I just tense the muscles in my neck and face and there's a rush of energy inwards from the rest of the body towards my head. Never thought to look in a mirror while doing it, but also confirmed the same thing happens to my eyes. It's rather exhausting to do though. A few times and I feel wiped out.

[DarkourParkour129]

@necromatter ive been able to do it since i was like four. like you also tremble if you do it hard enough and ur heartbeat stops then gives a hard THUMP and goes faster. never knew anyone else can do this. i would like to know what it is

[Sparksterfu]

Its supposed be autonomic, your not supposed to control it. You have a gift.

[nicolemasso]

ive always been able to do this, and didn't know it wasn't normal until someone pointed it out to me. i usually do it when im trying to read a persons intentions, it just feels like mass amounts of concentrated energy coming out of my eyes. I turn it "on" by micro focusing on the person or object im trying to analyze.

[solitairirose]

Woooowwww i can do this too! (although its a bit challenging because i just got into it) how can u better focus to get them to do this whenever? like, say...in the dark

[Kurtplox]

I can do this too. It's like a voluntary adrenaline rush. I do it, and my pulse beats faster, my eyes dilate, and it feels crazy

[gTauTomaTisch]

Hey,i know it!! If you see a dark place,your pupil expands!!

and if you see light your pupil back to normal!!

[vanderwoodsen90]

omg ur pupils look like they're pulsing.

[notforclimbing12]

unless youre 1/2 reptile, your intrinsic ocular muscles are smooth muscle. in mammals and amphibians pupil dialation is an autonomic response. unless adobe can alter your genome too...

[ArcaneArteest]

@notforclimbing12 Exactly, tells you who our common ancestor could be.

[541R0]

@notforclimbing12 u cant control autonomics, but u can learn things/do things which do affect autonomic input, so it becomes an indirect control.. its not unusual.

[z3bigmonst3r]

@notforclimbing12 And? If you read the description (regardless of the biological inaccuracies) you can tell that he is describing dilating his pupils by using his thoughts or emotions to trigger the autonomic nervous response of pupil dilation. You can't actively control your heartbeat, it's an autonomic process. However, stop and close your eyes and imagine yourself in a physical fight with someone you wouldn't mind giving a black eye or two. You just voluntarily sped up your heart rate.

[hoyt596]

@notforclimbing12 people have been studied that can control some of their autonomic responses. A monk dude was recorded increasing his heart rate to 300 beats per minute for a short time. Thinking hard about something intense can trigger the release of any number of chemicals from dopamine or cortisol to adrenaline.

Though it might still be fake.

[metalhead33]

hes probly lookin at porn

[Strawberrysunset23]

Do u know wat it means wen ur pupils are medium sized?

[arjont]

i like your scientific explanation

"i just flipped some chemical switch inside one of my glands in my brain, and it shot adrenaline throughout my body"

Ahahah too funny xD

[liberator279]

WITCH! WITCH!

[atvonz]

americas got talent

[Buckeh]

Lawl anyone can do this if they press on their carotid artery because the nerve that controls pupil dilation runs along it!

Not recommended for long periods of time unless you want to pass out on the ground!

[NatalieAutumn97]

how do u do that?

[SimlishSammy]

I want to know how'd you do it...so how did you do it, exactly?

[marley40869]

why does this happen to me

[vanessssaa]

Magic man.

[PoetryRocksGadgets]

Thanks. I appreciate this video.

[thedragonslayerking4]

i can do it

[macking420]

Haha, ya LSD is a very good way of doing this - not to mention you have the added benefit of a psychedelic experience. I can do this too (without LSD), I've tried explaning it to people, but I don't know how to explain it as it is pretty much all mental, I don't 'flex' any kind of muscles in my eye's or tense up or anything, but I do feel a rush throughout my body. It's almost like that feeling you get when you go down the hill on a roller coaster or any kind of free fall...

[pMcARDENboyz]

take mdma

[Jorjeca]

look like an anus

[greeniem]

can't imagine this fag can count to five

[coltpcker]

Dam I saw this and said I have to try it and I did it woo!

[nandakumarjr]

such a crap man..!!

adrenaline........??, one of gland on my brain....??, .physiological anomaly..?what a use of terminologies..what a BULL SHIT reasoning man!!

[dwind55]

hey man i ran across your video the other night and tried it out. turned out i had a natural talent at it and was able to dialate and can do it quickly on demand. its as if i found control of a new muscle. also discovered i could wiggle my eyeballs. thanks for helpin me find the hidden talents man

[lolitadoll646]

I want to do this. tell me how!!!

[cpmc1]

How do you do that?

[BloodXSweatXGuitars]

what he hasnt told you is that hes actually on lsd. lol j/k of course.

[1h34rtmus1c]

You've figured out how to dilate your pupils at will? There's this thing I can do to make my vision kinda blurry- do they dilate when I do this? Can I train myself to dilate my pupils?

[petitmacaque]

@1h34rtmus1c its just because your eyes are out of focus, everybody can do that

[myfavoritejuice]

jajajja yo tamien lo puedo hacer xDD pero no es adrenalina, es activando el sistema nervioso =D

[quest8899]

When are you going to make another video

[va1903wb]

and thank you for my research on eyes hehe thats a lot help full

[TFWC88]

Dude....you are a m a z i n g

how the hell do you do that

[Stallion769]

I think your level of stupidity is a "physiological anomaly" ... Your adrenaline explanation was a laugh out loud experience for me. Just watch the other pupil dilation videos on youtube to get your answer to why MANY can do what you Barely did.

[brianng999]

@Stallion769 Why? The pupillary dilator muscles in your eyes are wired by sympathetic nerves (Fight or flight response). If you make yourself feel scared or angry or wtv your pupils should dilate.

[rocketshiptothemoon1]

i can do that. :)

[CHudsonStudio]

I can do it too.. Usually happens when i focus on something close or far away..Ive practiced it over time to the point i can focus my eyes at different distances without anything being there..Dunno if my eyes dilating at that is just part or it or not..I could record it and upload it perhaps?

[thixotropicmusic]

i used to scare the crap out of my parents by doing this

[Jjoohnyy]

Thats pretty cool, i just tried to do that. 'tried' being the dominant word there. I have very reactive eyes, by this i mean.. if i've had a few pints, i look like i'm on pills. The same applies to a higher extent, if i'm on pills, i look like i'm in space. Much more so than others too. I was wondering if anyone had any information relating to why this is? I always thought that our pupils changed depending on the light, i have extremely good eyesight in dark conditions and wear contacts.

[jonnyBB3B]

shit thts amazing!!

[MrSgrobot]

actually its quite easy, just imagine focusing on a fake object right in front of your face, your pupils will accommodate to focus in on this fake thing you are visualizing, you can also make them contract by trying to stare through your mirror, imaging you are focusing on something 10 ft behind the mirror and your pupils will contract

[Rochell0]

so is it true if a guy likes u::there pupils start to dilation??? i know this sounds stupid and corny but just was wondering...

[RedAxle]

@Rochell0 Yes dialated pupils can sometims signify a friendly feeling, infatuation, or attraction. So it is possible that he likes you, but if he has dark eyes his pupils may just look large

[RedAxle]

@Rochell0 Not sure how old you are, but if you are at a club or something when you notice his eyes are dialted it may just because alcohol intake becuase alcohol as well as other drugs can make your eye dialate.

[LordViltor]

holyshit! i have always been able to make myself like feel a rush by thinking soo, like adrenaline rush and after i saw ur video i went ahead and did it infront of a mirror and mi pupils did dialate.....just like urs XD

[shanfran144]

I know this is not fake because I also can dilate my pupils voluntarily. I just discovered this recently. It's strange I don't have to think anything I can just do it. Its cool to know other can do this as well...I wonder why some people can and others can't?

[diorVon]

I've been trying to learn to dilate my pupils because I've heard it's more attractive than regular pupils.

How exactly did you do this?

[Razberry52]

I don't think I want to know how to do this.

[willywonka6]

holy shit i learned to do it, fucking crazy!

[jessica1205figueroa]

@willywonka6

how?

[IamironLan]

I can do it too, I might post a vid response

[xweaker]

is dialating pupils, the pupil going biggerand staying there or bigger and smaller alternating the size?

[SmileSharer9798]

god this freaks me out !!!! but kinda cool

[areallylongassname2]

Iv'e been able to do this for years without knowing, I use it to get pumped up during heavy lifting and it actually helps me lift.

[katberkery]

I can also voluntarily release adrenalin but I never noticed it made my pupils bigger as well. I've been able to do this since I was a little kid but never could describe it to anyone well enough that they knew what I was talking about. I can speed up my heart rate and then deliberately slow it back down again as well. This is the first time I've ever found anything online about it. Have you always been able to do this? Do you think it has any merit when it comes to meditating?

[berry704]

how do u do it? i wanna learn! :)

[Applepipe419]

you are an alien. I know you are.

[mj011n1r]

i can do this...dialate my pupils at will. Your description of adrenalin rush is apt. I feel strange when I do it.

[Sherpaful]

This is probably nothing more than a response of your sympathetic nervous system, which releases adrenaline causing dilated pupils.

[kokopuffs590]
