I just started wearing reading glasses a couple of years ago (Thanks, 40), and I've had some interesting reactions. This one contractor with whom I've worked for over four years made a comment a while back. We're pretty close and joke around with one another while working, but he told me that he always thought I was nice looking, but he found me very attractive when I'm wearing glasses.
That was so completely unexpected and I blushed. He apologized and said it was an honest observation. So now it's a joke when I put on my glasses around him. I say "Look, not" and then I put on my glasses and say "Hot." We laugh.
I kept thinking of that old saying my Dad used "Men never make passes at women who wear glasses." Guess not so much anymore.
