Windsor glasses

Traditionally the bridge of Windsor glasses is a "saddle" (a simple, arched piece of metal joining the two eyerims), and hence to prevent the glasses slipping off the face the temples are "riding bow temples" (a strongly arched wire that hooks around the ears); however, in a modern and extended definition, Windsors typically have a bridge with nose pads and gently curved temples.

[4][better source needed] The minimalist nature of Windsor glasses presents some pragmatic advantages over other styles.

Eyeglass lenses were historically made of glass and had to be ground against an abrasive surface to fit the shape of the eyerims.

The thin frame requires less metal, and therefore costs less to produce, although the corollary of this is that Windsor glasses are more easily broken if crushed.
