Update: I had both my old and new glasses measured at another store and at Costco and both were reasonably in spec (both gave me numerical printouts). The other store explained that the new Costco progressive lenses are digital and some people simply can't adjust to them. Obviously I'm one of them. My old glasses are non-digital Ovation lenses. And I just met up with a friend who had the same problem with digital lenses that were NOT from Costco. So I had no choice but to return the new glasses to Costco for a painless refund, and as my prescription had not changed much, I am back to my old glasses and not giving them a second thought. Unfortunately, Costco only offers only this one digital progressive lens and nothing else, which is too bad since they are very professional and about 1/3 the price of everyone else in my area as well as less than the major online suppliers (which for progressives-just don't do it!). It was a rough 3-4 weeks giving the new glasses a try and getting nowhere and it wasn't subtle-great difficulties with the computer screen, headaches, and noticing blurry areas constantly. When I went back to the old glasses the stress relief after only an hour was remarkable. The takeaway from all this is to KNOW if your existing progressives are non-digital that you might have difficulty adjusting to digital ones, and don't let anyone BS you that it's only an "adjustment" of the frames. When I first switched to progressives many years back it took all of about 2 days to be comfortable with them.
FYI, I contacted Optik about the Jena HD 4K and according to them they are not available in the US at this time.
