How to move one eye on its own (and the science of eye movement)

You can train yourself to move one eye independent of the other. Here's how to do it. I also talk about the science of eye movement: saccades, smooth pursuit, vestibulo-ocular and vergance.

8:29 "do this now, close you eyes"
Me: ok *eyes closed*
8:36 "ok, now turn around like this"
Me: like what?

I too learned this ability when I was a kid. It's a useful skill — drives the ladies wild! No, wait, away. Drives them away. That was it.

This is a handy skill to quickly solve those "spot the differences in these two images" things. Crossing your eyes will overlay the two images, making the differences instantly obvious.

I've tried this and now im permanently blind in one eye. I knew holding one eyeball in place with a screwdriver wasn't a good idea

thats the first time a youtube vid said that “it is easy” and it actually turns out easy

[chromberries]

I learned how to quickly give myself a headache, thanks.

I used to cross/blur my eyes all the time without needing to focus on something and didn't even know that one of my eyes moved and the other didn't until a friend pointed it out. It's certainly a fun gag to pull on people when I get bored LOL

I have now obtained a pointless, creepy skill that will probably not help me in any concievable way.




Thank you.

Man, everyone must've looked so weird watching this...

[thunderwolf]

me, who only has one working eye: yes this will be useful information

[blockoftrash]

This guy: breathing is involuntary
Me: *starts breathing voluntarily*

Oh my god. As soon as you said “you have to follow one side while crossing your eyes” I was able to do that trick and I laughed so hard when I filmed my eyes and realized that I can do it.

[PeidosFTW]

Jokes on you, I only have one eye so only moving that eye creates that effect with no work

8:30 "rest your fingers on your eyelids, do it now"


"Now move like this"

Interesting. I always did the "move just one eye invards" trick by imagining a fly flying near my face in front of my right eye and trying to focus my eyes there. This causes similar movement but also moves focus point to really close which causes extra eyestrain. Doing the trick you're describing here and just keeping one of the double images static makes it easier to do the same trick without close focus.

"you will *smoothly* pursue my finger"

Thank you for the story on Susan Barry. Amazing! Don't let someone tell you that things are impossible, test it for yourself. :) Thanks for sharing this with us.
