1834 George Richards Elkington patented two developments in one go under the heading An Improvement or improvements in the construction, making or manufacturing of spectacles (Patent 6692). This involved firstly an angled joint resulting in a tilted forward frame. Secondly it introduced the pantoscopic frame with a flattened 'pantoscopic' rim to allow distance viewing over the top of reading lenses. This was the ancestor of the twentieth century panto-round-oval (PRO) eye shape. Steampunk, Optical, Eyewear Design, Manufacturing, Eyewear, Eyeglasses, Goggles, Optician, Jewelry Art
