It varies a lot depending on the face of each girl, at least in my case. The face is key but sometimes the overall looks define wether a girl looks good with or without glasses. I personally like the girls who look sophisticated with glasses, kinda like a cold, too serious entrepreneur/librarian that hides a savage sexy beast within, it makes me crazy.
You might be able to look fine with glasses, but there's pretty much no woman alive who looks cuter with glasses than without. I wear contacts myself, and plan to go buy an aftermarket upgrade for my eyes later this year.
