I finally checked it in person last week. At least Superfocus actually did what was supposed to, just too clumsily and it was really ugly. emPower! was confusing. I had read about it but when I discussed it with a sales person and tried a couple of pairs I saw little benefit. I had thought that it would switch between all distance and trifocal progressive but apparently it merely eliminates the reading part of trifocal. Plus, even the sales person was confused about what mode it was in. I told him that I saw no change when I tapped the side. He coached me to do it differently. Finally he looked inside and guessed that it was in auto mode and that my tapping did nothing.
I was very disappointed.
