We’re going through a stage of monocle wishing here at the moment :)
Check out all the frames at Warby Parker, the designs are fantastic and very well priced – they can do this by having their own designs manufactured, cutting out the costs of external designers then selling the glasses themselves to cut out the markups that retail outlets would add. The company also donates a pair of glasses for every pair sold.
Downside – they ship to the US and Canada only… but that’s what freight forwarding companies are for!
Thanks to John for pointing out these guys.
