 Browline glasses were invented in 1947 by Jack Rohrbach, then vice-president of Shuron Ltd., an eyeglass company.The first browlines – sold under the "Ronsir" model name – were made out of interchangeable bridges, eyewires, and "brows," allowing wearers to completely customize the size, fit, and color of their glasses.At the time, most frame manufacturers offered a limited number of colors and sizes, making browlines a unique means of customizing one's personal appearance.
