Ful-Vue frames were a significant innovation in the qeyeglass industry starting in 1930. Until the early 1930's, the ear stems of almost all metal eyeglasses and sunglasses joined the frame at the centerline, halfway between the top and bottom of the frame. This had been more or less true for hundreds of years, long before glasses orders came within the reach of the average person. Ful-Vue frames changed all that. the late 1920's, the American Optical Company (AO), the largest manufacturer of eyewear and prescription lenses in the world at the time, filed patents on their new "Ful-Vue" design. The Ful-Vue idea was to raise the point where the arms joined the frame, taking them up and out of the way of the wearer's side vision. This innovation came at the same time many Americans were driving cars for the first time and thus were also using rear view mirrors for the first time. On some early production from this period, you will also find the ARCO mark, that stands for Acid Resistant Coating.
