Firstly thanks to martijnk who found the company that made his custom-made glasses (http://prince.org/msg/7/392493?&pg=4#msg_8807021)!

It's a German company from Berlin that's called ic! berlin.

It's highly successful with its "handcrafted screw-less sheet metal eyewear" as a lot of celebrities already wear it (Prince, Madonna...)

And that's what they wrote on facebook yesterday:

now look at that! the new billboard cover!
prince turning his swag on at full throttle wearing the ic! berlin täuschung in gold. a one of a kind masterpiece just made for him. the jacket, the shirt, the chest hair, the glasses. pure style, pure genius, pure love. look at that! LOOK AT THAT!
in march you can see prince smashing his guitar live in front of a billion people in our NYC ic! berlin store (77 christopher st). lady gaga will be there as well. and tiger woods. and al gore with his vegan CO2 bus.

The store's address: 77, Christopher St.!!!!

(p.s.: and no driver needed as the glasses haven't got any screws...)

(plus danke schön to Girl6 from the German board!)
