I pasted from the site, and it had the "TM" (trademark symbol) after the 3C.
Sorry.

Yet, a search of google archives does not come up with a single instance
of this technology being discussed in any aviation newsgroup.

When I asked my optometrist's dispenser, they claimed never to have heard
of it.

Anybody using this technology? Any comments?
