In a well-lit room what are some things that can cause the pupils of the eye to dilate?

I know drugs are one thing, but WHICH drugs. Any OTC ones that might do that? Which prescription or illicit drug types would do it?

Are there non-drug reasons, other than LOVE, of course.

Well heck, maybe love is the answer?

(don't worry, it's not me, or about me!)

thanks!

Some people have naturally dilated eyes, hence the term 'bedroom eyes'. In early Italy (Mona Lisa's time, I believe), eyedrops of belladonna were all the rage to achieve such a look. Do not try this! It is very poisonous!

More useless trivia from your friendly neighborhood autodidact. *grin*

My roommate is on a lot of drugs and one of them makes her eyes really dilated. She's got depression and anorexia if that helps... [Dont Know]

Anti-cholenergics can cause this. Most common would be anti-histamines such as Benadryl.

Edited: My being stupid and mixing up my drugs.

o_O Not good when a pharmacist mixes up drugs [Wink]

Also, if you're nicely nearsighted, your pupils tend to dilate way more without corrective lenses...trying to get more light, I suppose.

But I'm told in the morning, my pupils look blown.

I have bedroom eyes! [Big Grin]

Some OTC drugs, like antihistamines as already mentioned. Dextromethorphan used in a non-approved way can, but I am not sure about regular usage. Some psychedelics do so as well.

Posted by Tullaan (Member # 5515) on :

Dextromethorphan (the dm in robitussin dm) is actually a codeine derivitive and will cause constriction of pupils.

Thank you all!

This isn't for me.

It's for a worried mom I know...

Posted by Rahl22 (Member # 1376) on :

Oh, and having asymmetrically dilated pupils (only one is "blown") can be a sign of severe brain trauma.

I assume this is a fairly moot point, though.

Posted by Danzig (Member # 4704) on :

Well it dilated mine and several other people's...
