Also for those with high prescriptions, were you advised to choose smaller frame sizes?
"high definition" is a gimmicky term. Free form or digital surface is what you're looking for. As well, they are not all designed the same. We all have laptops, which are great, but not all of them function as well as the next. Same thing with the digital lenses. It is the computer program that makes them good or bad. For instance, Hakim (in Canada), Pearl Vision and Lens Crafters makes house brand "high definition" lenses and they are junk. Don't bother with Hakim, at all, they bought old technology machines and software, which defeats the purpose of "new technology".
In any case, with your RX, you will see a good difference in vision. It will help your peripheral vision, the lenses will come out a "bit" thinner and so it will be lighter as well. But the biggest improvement over regular lenses will be the peripheral vision.
As for the frame, you can pick any size frame. With the true digital lenses, they will make several measurements to customize the lenses for you, in your rx, into that frame.
