I'd go with Zenni, as I have a pair of their progressives, but I don't like the narrow corridor that they have. :( Would like to try a pair of the Essilor Definity lenses, but no one online has the trivex models, just the CR-39 and poly, and CR-39's no good for rimless. The only trivex pros I've found online so far are Younger Image (narrow corridor), or Hoya Lifestyle ID's ($531.00 <ouch>).
Maybe I just need to give up on these rimless frames I've got (nice wireframe Zeiss'), and get a decent rimmed frame (Shuron Ronsirs) and get some CR-39 lenses instead. If I'm going to have to pay prices like those Hoya's, then it's goodbye rimless, hello bold and bulky. ;) -=# Firewalker #=- On Mar 26, 1:26 pm, powrwrap <[email protected]> wrote: > > On Mar 26, 10:26 am, Firewalker <[email protected]> wrote: > > My question: is this is a problem inherent with all polycarbonate due > > to the low Abbe values, or is it a problem with the Varilux brand > > themselves or the Crizal AR? > > Do the other brands (like Zeiss or Nikon) have this problem with their > > poly lenses also? > > Like yours, my prescription is not strong: -1.25, 0, 0, +2.25 ADD. > I've had two sets of rimless glasses from Zenni.

Another choice is Trivex (abbe value = 1.44).
