We’ve been writing about this sunglass many times before, (HERE) and (HERE). But as it’s one of the most googled frames and also a lovley sunglass we would like to do it again!
Below you can see the classic Persol 714, which is the folding sunglass that Steve McQueen wore in the movie Thomas Crown Affair. The blue lenses gives the sunglass a relaxed look.
Bonocle 
Where were these particular ones purchased from? or where were the blue lenses from?
