OptiKing
Berlin
This store is conveniently located on Eberswalderstraße in Prenzlauer Berg, not far from the Mauerpark flea market where they also have a stall on Sundays. If you know what you want you can order on their online store, but it's best to actually go in to the store to try some on.
In store you will find more options than what is listed on the website, from 'Cats eyes' of the 50's to classic 80's Christian Dior or original aviators, Top Gun style.
This shop is not the place to come for a pair of cheap sunnies to chuck in your beach bag. These are all legitimate frames that can have prescription lenses inserted and the price tag shows you why. Expect to pay a decent amount for these frames, depending not only on the but the era and style but the brand and quality as well: a lot of them are unworn before they hit the shop.
If you are looking for a pair of frames that no one else in town is wearing, you should definitely head to OptiKing
