Studies with low barriers like superficial observation are easier to fund and approve.  There's nothing about this that screams expensive or intrusive considering the population of juvenile subjects. 

Just wondering what the study size was though.  I'm not paying for the article. 

I'm figuring you might find plenty of short eyelashed people with allergies. 

Plus, how did they find the people for the study?  Did they ask for people with just long eyelashes first, or people with long eyelashes and allergies? 

I also wonder how the heck people manage to get paid to do a study like this?  I mean, correlating eyelash length and allergies?  How do you even think up that, let alone finding funding? 

I wonder if the linkage is actually to the atopic (or one of them) gene cluster.  DD and BF both have super long lashes, my mom did, but DH and I don't.  (All of us are atopy poster kids).

Not the case for DD....just ask her mascara wand!

I've heard a correlation with Denny lines under eyes, but never length of eyelashes, very interesting

20 years ago our pedi told me DS would likely have allergies simply based on his long lashes.  He was right and then some.

How interesting.  My kids and I (well, I used to) have ridiculously long lashes.
