There are two things that occur to me: -narrow corridor: has your add changed? if it went, say, from 1.5 to 2., you'll perceive a narrower corridor because of the greater difference between the center and sides. I had Varilux Comfort before my Zenni lenses, and the Varilux did have a wider corridor.
-color fringing: sometimes you will see this more with polycarbonate than with CR-39. CR-39 has the best optical quality, but is thicker. I think Zenni uses CR-39 for their basic Progressive lens; it's a little thicker than other glasses I have with polycarbonate lenses. Hope this helps.
