The frames that I find most desirable, which are the ones that are just one springy piece of titanium, with no actual hinge, I think come from a specialist spectacle supplier. The design, the looks, are superb, and they are very light and probably comfortable to wear (I nearly got them, but chickened out at the last minute).
Designer names put me off. Maybe its inverse snobbery, but I just don't like that culture. I would never wear anything that actually displayed such a name --- partly because, if they want me to advertise them, they can pay me, not the other way around!
I also distrust the entire system, suspecting that it is quite probable that the "name" never had anything to do with the design other than selling the label.
I'm just cynical!
(My last pair of specs fell apart. I' currently wearing the same lenses, inserted into a new Rs.500 frame by a guy in a tiny local shop. They are cheap, and they feel cheap, not keeping their springy grip at all. Sometime soon, I'll get them replaced by something more sturdy, probably around rs.1000)
