@contrex,
As you likely know, since you have a sharp mind (not sucking up, it's a true fact), some fair portion of women like me like guys for their minds, and of course other body members - movie star handsomeness not a requirement. Myself, I was no 'dog' in those days of yore.
Lots of us have had thick glasses, but my own now are fairly thin, even the legally blind eye lense. I'm lucky the other one is good enough for seeing. Years ago, I wore contact lenses for vanity's sake (some funny stories there). Then I said the hell with it, re the bother, and went back to glasses. We don't know where Jack91 lives, but there are various lenses available other than "coke bottle" - money, of course. I've no idea of prices now since my eyes are stable. I had an old friend who had coke bottle glasses, one of my female pal group, and was very happy re contact lenses.
So, this breaks down to Jack worrying about being dismissed re his glasses and about how this makes him feel. Contrex didn't have attraction problems, probably because of a fair level of self confidence. So, to me, self confidence is what to work on.
