Bow folding spectacles, England, 1650-1750
Bow-shaped spectacles were difficult to wear. The wearer had to tilt his or her head back slightly so they would stay on. They are hinged at the nose and made of horn. Horn was a cheaper material than the more luxurious tortoiseshell. This suggests the owner was not wealthy. Horn is taken from animals such as sheep and cattle. It becomes brittle over time due to moisture and intense heat and snaps easily.
