Spectacles
Transparent objects were used to help (1) defective eyesight in antiquity: the best-known case it that of the Emperor Nero, who watched (2) performances in the arena holding in front of one eye a jewel with (3) curved facets. Lenses placed close to the eyes were first used towards the end of the 13th century. Nothing is known of the (4) inventor, or of the date or place of discovery, as it was the work of an (5) illiterate artisan, but Edward Rosen fixes the period of discovery to the five years after 1280.
The creator of this (6) invention was probably a glass (7) worker who made ornaments and glass discs for windows.
