I'm gonna call Spy on this one. Much like the big O, they're trying to use catchy buzz words to make their lenses sound far far better than reality. This is not to sat that Spy are inherently bad as such. But I would feel completely comfortable saying they're nowhere near as "advanced" as the claims they're trying to make. We actually work with Carl Zeiss Vision on a daily basis in our shop, and I've been given a bit of the backstory on the Spy lens thing. For those of you who aren't familiar with Zeiss, they're a German optics company specializing in all things lens related. Been at it since the 1850's commercially if memory serves. Carl also worked with the likes of Otto Schott and Ernest Abbe - big names in optics and physics to this day. In short he was a smart guy, and Zeiss has been a leader in precision optics for all sorts of projects including IMAX, NASA (Apollo in particular), planetarium projectors, photographic lenses and filters, & medical optics (microscopes, scanners, cameras) - generally done through their sister company Carl Zeiss Medictec.
In short, Zeiss is, and has been for many years, generally synonymous with high quality optics.
Obviously there are going to be other manufacturers of optical products (such as ski goggles) who find the Zeiss pedigree very appealing. There have been a number of Goggle manufacturers who have worked with Zeiss in the past to improve their designs including: Smith, Giro and of course Spy. Simply paying the license fees, and slapping Carl's name onto a given goggle does not perfect vision make. The terminology used on the Spy website is anything but intelligent as it relates to optics. In their defense, there are some things they get right, but there are more that they get very wrong.
To each their own as I've said before. But be aware of what you're actually reading - or getting if you purchase a goggle that likes to throw around lots of slick sounding terms and name dropping their "partnership" with a company like Zeiss. Caveat emptor is a wise mantra... Using the name doesn't guarantee that the company hasn't changed things to their own liking and diminished or even completely obliterated any benefit they had with the original lens design. In fact, it happens more frequently than you may think...to say nothing of the lack of quality control that many "optical" companies in the sports biz have when compared against say a true Zeiss prescription quality lens.
When in doubt, you are always wise to seek out a certified optician who deals with winter sports optics for assistance. And if you're heart set on your own set of Carl Zeiss Vision lenses, there's a good chance you can get set up. My personal preference for wrap Rx is the iProfiler system, which uses a combination of auto-refraction, Haag Streit aberrometry and corneal topography, in addition to your optometrists manifest refraction results to correct for numerous higher order visual aberrations in the natural eye. Combined with precise position of wear measurements by your optician, you'll be able to maximize your vision across the entirety of any moderate to high wrap Rx goggle needs.
Yeah. It's pretty cool stuff.
Personally, this optician feels there are far better optics available in goggles today than the bulk of the Spy offering, Zeiss or no Zeiss. Although, if you do happen to find a Spy on killer sale or closeout someplace in the color you're after, I say go ahead and pull the trigger!
