My understanding, and there may be a lab rat or Essilor employee who can correct me, is that Xperio is basically a rebranding of what had been Essilor's previous polarized lens with Crizal SunShield. So they should be functionally identical.
What part of "other optical manufacturer or vendor" are you?
Judging by his past posts he sounds more like a consumer to me...Quote:
