Is it possible to manually dilate your pupils?

My boyfriend can. Its REALLY creepy.

I can! And everyone I’ve ever told though I was crazy. Great Question. I’ve always wondered if other people could.

@PTPH, any insight on how you do it?

Eh, not really. I just kind of do it. I don’t know how. I’m sure it could be learned, I assume all it is is learning how to control a particular muscle. I’m not even sure what I’m doing when I do what I do. I might be dilating my pupils, or I might be doing something else. All I know is that when I do it my vision blurs, and lights and such look bigger, as if my contact lenses aren’t in.

The following is highly theoretical:
This might help, but I’m sure it can’t be good for your vision. If you don’t wear glasses, find someone who does and put on that persons glasses. (Or f you wear contacts, find someone with a significantly higher prescription and put that person’s glasses on while you have your contacts in. Or if you wear glasses, try putting the other person’s glasses over yours.)

You should find that although everything is blurry initially your eye will be able to adjust, at least for a few seconds, making everything clear. If you can figure out what your eye is doing as it adjusts you might be able to learn how to adjust it voluntarily.

“All I know is that when I do it my vision blurs, and lights and such look bigger, as if my contact lenses aren’t in.”

Oh! I can do that! I do it sometimes to entertain myself when I’m thinking about stuff and don’t have anything better to look at. I’ve never had anyone else look at my eyes while I’m doing it, though, and I definitely can’t look at them myself, so I never even thought to wonder what they look like…

Hold your hand over one eye and the pupils of both will dilate. Or just ‘relax’ your eyes. Like pete said.

MDMA or LSD

Do you mean “voluntarily”? “Manually” involves using your fingers to shove your pupils around.

Haha, then voluntarily.

That’s a relief. You can imagine what I was picturing. See famous image in Un Chien Andalou by Luis Buñuel.

Read The Synopsis to find out what happens to THAT eyeball.

AH! I didn’t want to see and/or read that! It was quite unsettling in the stomach area.

@Pork; for cinema buffs, the movie (and its surreal images) was notorious and generated many derivatives. Consider the peek you just had as a cultural experience.

Haha, alright then, I’m into a different kind of movies like the independent films and somewhat known as sideshow attractions instead of the mainstream films-and even then I’m still selective.

I can dilate my pupils at will AND it feels good when I do it, it’s kind of similar to the way certain drugs have made me feel – I know that probably sounds ridiculous but it’s true. I first realised I could do it a few months ago – anyone else that can do this?

Yes it is, because I can! I’ve never known anyone else ever able to do it before like me!
