How different is this from aspheric lenses, which are also fairly recent? Or is aspheric mainly for the purpose of making lenses thinner, and doesn't improve the accuracy over the common spheric lenses? I would guess that HD is a particularly fancy type of aspheric lens.
One thing to keep in mind. It's not as though your lenses stay in exactly one place relative to your eyes. Adjusting the nosepieces (or just moving the glasses with your hand) changes the position of the lenses. Before plunking down a lot of money, it would be nice to hear from some people who've tried them. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://glassyeyes.blogspot.com!
