Brief history of imaging devices
• Eye-glasses(1-st century or earlier)
Pliny the Elder wrote in 23-79 A.D.:
"Emeralds are usually concave so that they may concentrate the visual rays. The
Emperor Nero used to watch in an Emerald the gladiatorial combats."
The modern reinvention of spectacles occurred around 1280-1285 in Florence, Italy.
It s uncertain who the inventor was. Some give credit to a nobleman named Amati
(Salvino degli Armati, 1299 ). It has been said that he made the invention, but told
only a few of his closest friends
