What is it with glasses

I've a few pics on my TV chix account and on flikr and the ones that get the most attention and comment are ones with glasses..

I'll admit I like it when my wife pulls her glasses down a little and looks at me with her big brown eyes over the top of the rim of the glasses.. is it a teacher thing? a sexy secretarial look? a look of you're about to be told off or something else? Melts me when she does it to me..

Anyway if anyone's reading this.. With or without glasses what do you think? and what's so sexy about glasses?

p.s. Yes that is the length of my eyelashes with mascara on.. I'm blessed with womens lashes and boy aren't women jealous of men with long lashes..
