Curious, this sent me off on a journey of discovery.
I have utilized Corning glass in areas such as Pyrex and Corning Cookware. One of my favorite eye-glass brands (was) Serengeti due to the chromatic change technology they had. I still have a pair of them, but sadly they were chipped on a drop many years ago. Seeking them out a couple of years back seemed to dead into Luxotica's acquisition and watering down of the Serengeti brands as it merged them into Ray Ban.
According to the webz, it appears that Corning still maintains control of the name brand so now I am going to hunt around and see where a fellow could purchase another pair, if possible.
Oh, and Gorilla Glass is cool too...
