Naturally most people don't want to look like their grandma, so these mainstream-vintagesque goggles are the norm. I saw an ad for www.deadmensspex.com in a tattoo flash type magazine & thought, 'at last!'.
The website is obviously run by an expert in the design of the previous century. The frames are sorted into their respective eras, and are true to the time periods. Now here is the best bit, Dead Men's Spex can fit your chosen pair with your own lens prescription. So you can now have your day-to-day glasses match your vintage clothing.
They also can fit tinted lenses, or prescription sunglasses. I ordered myself a lovely little cat's eye librarian pair, which arrived in an equally cute box.
