Fielmann.

Incase it might help,

I was back in England this weekend, I've needed to get my eyes tested for about 2yrs and had a spare hour so went into a local Vison Express. Normal service but whats very interesting is the group that they are owed by has shops in Switzerland, so after buying glasses and frames in England, they can transfer and deliver to Switzerland, and also assured me there wouldn't be any extra tax as they are just transfering between offices. I'm expecting the glasses early next week so I'll find out then whether its true, but its an absoulute bonus if so.

He also mentioned they send contact lenses over to someone else based over here every 3 months and they don't have any issues.

Maybe might save some people some cash!

I followed the advice from here and I went to fielmann yesterday. Indeed good prices and good service! Got glasss for my son and they offered me a free check...they told me I am good and should come back in two years
Funny...I paid only 30% more than what I paid in Romania...and the quality is better. Considering the income comparison I was really surprised to have a good deal on Bahnhofstrasse

i use zennioptical.com
they have TONS of styles and are really cheap. i've used them for a few years just so i have a buncha different ones to choose from when i want. you just have to put in all your prescription info.
