well, I've never seen someone without lenses in glasses.. but about wearing glasses when you don't need them.. I'm short-sighted, wear contact lenses but I think the fact that people wear a certain kind of glasses as fashionable (ray ban I mean) is helpful in a way that if I had them, it wouldn't be obvious if I need them or not ;d but I don't do that anyway, generally, no I don't take it as offence, more like -it's ok to wear glasses- form of consolation and solidarity xd
