From reviews I've read they are an improved progressive lens from the technology of 20 years ago. I tried progressives back then and they didn't work as good as bifocals for me. The HD lens makers now say you get a bigger viewing area and straight lines appear straight. My optician friend gets to try all the latest expensive HD stuff. He wears the basic varilux comfort because can't see any better thru the more expensive lenses.
