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.
I'm Andrew Hamm and I approve this message.
What part of "other optical manufacturer or vendor" are you?
They both block uv400 transmittance and they both have the UV400 absorbtion on their backside coatings
