Quevedo spectacles are a particular model of spectacles with optical lenses, used to compensate for vision deficiencies. They are named after the Spanish writer Francisco de Quevedo. They differ from other types of spectacles in that the lenses are enclosed in a simple frame. They are usually made of metal and are held in place by the nasal septum, as they do not have temples. They came into use from the 15th to the 17th century and occasionally also in the early 20th century. They began to be introduced as a rare luxury item for the wealthy classes.
