PC has the worst optical quality. I don't use progressives but if I did there's no way I'd select PC (I've had it in the past and am not doing it again). You can google polycarbonate optical quality and get some information on the various lens materials but here's one link http://groups.google.com.my/group/sci.med.vision/msg/18d888383c766170 or this (scroll down to the reply by 'Mark A') http://www.docendi.org/high-t58442.html I don't use PC in any of my glasses. BUT whether it's acceptable for *you* and not *me* is going to depend on your prescription and your sensitivity to the aberrations. Also it is often recommended where safety might be super important eg someone who only has good vision in one eye or children who fall over, might get hit in the face by sports bats etc. For optics though, I wouldn't do it, and I have a moderate prescription (the worst of it is a -2.75 cyl in one eye).
