Fielmann is great. The process of getting glasses there is quite streamlined. Their Null Tarif glasses are really cheap. They also offer polycarbonate lenses - blender plastic.

They just paid for themselves this month: there's a big dent right in front of my retina from a rock thrown by another vehicle.
