The earliest form of spectacles may have been made by the Venetian glass blowers in the 14th century, who made optical lenses from glass and fitted them into horn rim frames.
When the lenses were connected to arms hanging over the ears the term "spectacles" came into being. The word spectacle seems to have appeared in the 18th Century, used to describe a pair of lenses resting on the nose.
