We have probably listed thousands of these Ful-Vue frames over the years. The Ful-Vue design, where the ear pieces joined the frame higher up on the frame, were patented around 1930 by the American Optical Company in Southbridge, Massachusetts, and quickly became the dominant frame style in mid-century America, until cat eyes and "browline" glasses came in to vogue in the 1950's and '60's. Even today, a large number of modern eyeglasses are influenced by the vintage Ful-vue. We have put together a page show the history of Ful-Vue frames on our web site at http://clearlightoptical.com/Ful-Vue/.
