"These bold frames from Derek Cardigan flatter tapered jaws, tall foreheads, arched brows, and soft features. The saddle bridge sits comfortably on longer, narrower noses while flexible spring hinges bow outward to suit medium and large faces. Glimmering math symbols sit at each temple point for a final flash of nerdy cool."
