"HD" glasses lenses?

There is a relatively new fancy technology in eyeglass lenses: free form lenses for single vision, which some manufacturers are calling "like HDTV" for glasses. Really? Will I notice that much difference with MY prescription?
I've been lurking on optometry pro forums gathering info on the new Zeiss Individual SV or the Essilor 360 lenses, and opinions are somewhat mixed. On the one hand, they seem like a clear win for a complicated, strong prescription if you don't mind taking out a second mortgage for your glasses. They're supposed to make peripheral distortion much more minimal and reduce chromatic aberration. For me, I wonder if they will make $200 worth of difference, though; I am about -5 in each eye with no cylinder correction.
1. Do you have one of these fancy new types of "HD" lenses and do you think they're worth it? What's your Rx? How do they compare to standard, spheric high index lenses?
2. Are you an optician/opthamologist or someone with technical knowledge about these things, and if so, what would you recommend for a customer like me?
I have not been happy with cheap lenses at all in the past and I usually shell out for high index with Crizal, which is noticeably worth it. Will I notice the HD lenses too, or will it be like the difference between a 192kps and a 320kps mp3; very very hard to impossible to actually hear in an everyday setting? Has the quality on lenses surpassed our ability to discern much difference?
