Rust is dead on. Yes there is a HUGE amount of hype, or "Creative" marketing in the whole laser test. Sure, they use a computer to determine the exact dead spec "Optical Center" of the lens when initially cut, but that is where all that ends. I will give you a perfect example as to why it is less of an issue to cry over "optical center" versus what Hero stated about quality of materials/coatings and the actual XYZ.
I have a friend who wanted an RX set of lenses for his Flak Jackets. Sent in the RX to Oakley and come to find out, not a single pair of sunglasses will allow for his pupil distance to be set as an rx. In prescription frames, no sweat, sunnies, not happening. Turns out there is only 1 model of RX frames that are considered "sport" that work. Now, he has worn Flaks as his outdoor biking specs for a long time, only aided with contact lenses. So if his pupil distance isn't RX friendly for that frame/lens offering, how does the "optical center" crap play into his benefit as a general non RX sunny? Now, consider the other factors like your head versus someone else's head, versus the created dummy head with the laser test equip. Is that dummy head anatomically correct? No. It is just a model. Nobody has a head in which the glasses sit dead square on their head at all times. Most people, if not all, have one ear that sits at a different position than the other, while some people have a larger profile (fatter head) than others. So what does that mean? Well, if your dome is wider, that means your frame bends and the lens geometry now changes from it's original placement. Fatter head means an outward bend of the stems forcing and inward angle on the lenses. Likewise, the offset ears now means that instead of say the left lens sitting equal to the right lens, you now have it lower or higher (depending on your ear placement). It is all marketing at that point. Sure, XYZ is huge, but I believe the whole "optical center" ploy is part of the HDO optics rather than XYZ. I have explained it before in the past the same way as now: HDO and XYZ are awesome sales tools, yes, hdo has some warranted truth, as does xyz, but in reality a lab test is only a test. In the real world, each person is different and things just aren't equal at that point. When you order your prescription shades from an eye doctor, there are measurements involved to make sure you get the best optics possible for the purpose of correcting vision and making it better. When you run in to a retailer and grab a pair of Oakleys or anything else, it is simply off the rack to no exact fit.
XYZ as described at the Co-Pilot event is the taper correction applied to the lenses where the center is thicker and thins to the outer edge. That is to combat the bending of light as it passes through a bent surface. Let's not forget RayBan didn't use HDO/XYZ until Lux bought Oakley, nobody did.
