The turn of the 20th century was a transformative era mirrored in the evolution of eyeglass designs. Monocles remained popular, especially among the higher social classes, but eyeglasses were transitioning towards more functional and stylish forms. These rimless frames rested on the nose bridge, creating a unique but somewhat tricky fit. Spectacles with ear hooks were developed for practicality, while the use of new materials like tortoiseshell and metal began to offer more options in eyeglass design. This set the stage for a plethora of 1900s eyeglass styles that would define the upcoming decades.
