While I agree that all polycarbonate lenses *should* perform identically, I
have seen many posts about poly lenses with significantly improved optical
qualities. Guess where they came from? Zenni.
Many people have posted in the lat 6 months or so, that poly has never been
an option for them...but then they tried the Zenni offering and find it
entirely suitable. A quick search of the forum should turn it up...the
discussion was around 6 months ago, so that gives you a time period in which
to search.
Maybe Zenni is using something else, and just calling it poly. BUT,
whatever it is, it's an extremely cheap experiment. Might be worth a look?
