Although spectacles are everyday items, they change the faces of their wearers more than any other object. They are available in many different styles and colours, and are nowadays also worn as a fashion accessory making a statement about the wearer’s personality, mood or style. Their design continuously changes and is today significantly different from that of the past century. Spectacle frames nowadays primarily feature playful and striking designs or patterns. Thanks to new materials such as carbon-reinforced hardwoods, stone veneers and cutting-edge material processing methods such as 3D titanium printing, etc..., new shapes, which not long ago seemed unimaginable, can now be realized.
