Thanks! I visited Berlin just for three days during my trip across Germany and on the first evening I broke my glasses.
One guy in my hostel told me to go to Offensichtlich and ask for help. They were very kind and friendly and explained the opportunities - complete new glasses including lenses until the next day or fitting in my old lenses into a new frame. I know that the first choice would have been the smarter one, because after they tested my eyes I noticed that they have become worse. But this trip was expensive enough until this accident, so I just choose a new frame. Now I have an original handmade Berlin frame as souvenir from my trip to Germany! Best thing was they just needed one hour to make my new glasses. In between I enjoyed the sun and an iced latte at the Gendarmenmarket. Perfect!
Thank you guys & the next time in B. I´ll take a look for new sunglasses!
