When I was a kid, my next-door neighbor's father worked as a welder on the Washington Metro rapid transit system, so I learned a bit about the process from him. And I saw my father use a soldering iron in the garage. But until I began working on this article, I hadn't heard of brazing or thought much about the complex manufacturing required to produce something as outwardly simple as a pair of sunglasses.
