When I see those on someone, I have an immediate negative response before they even open their mouths. (of course, I reserve the right to change my mind as soon as they open their mouth to speak...)
Very few people can wear those.
I think Kat Timpf is one of the few that stick out for me.

Of course, while I find her attractive both physically and ideologically (I fully get she is a bit bony and has a hard face which not everyone finds appealing) something about her makes me think that, as a guy, I would approach her the same way a male Praying Mantis might approach a female Praying Mantis...
Kat does not need glasses to see.
She wears them so that people take her more seriously.
Instead of just a pretty young blonde girl

And let me guess? You would be enthralled all the way to your grave.
