Yes, indeed. Actually I live in HK and also a big fan of Ic berlin.
There is a chain store called "Image Optical 潮流天地" in HK with several stores located in the 2nd tier area (i.e. NOT the tourist or commercial area with expensive rent) and they sell a lot of high-end European brands like Ic! Berlin, Lindberg, Tag Heuer, etc. in affordable price.
In terms of a normal Ic Berlin prescription glasses, the discounted price is ~ HKD 2,700 - 3,000 without lens, and I found it is much cheaper than other big chain stores in HK.
Below are some of their shops located in different area in HK - Hope it is useful!
