@RRToTheMoon I see it the same way. What's more, Fielmann now has a lot of competition. Especially online. I personally don't feel comfortable in the stores. Advice on glasses is given right next to the sunglasses shelf.
@Dividendenrentner Personally, I prefer to go to my trusted local optician. Online, for example, I see Mister Spex in the lead. In addition, manufacturers such as Ray-Ban now also have their own online stores.
