“The evidence indicates that the use of lenses was widespread throughout the Middle East and the Mediterranean basin over several millennia”. The earliest explicit written evidence of a magnifying device is a joke in Aristophanes’s The Clouds from 424 BC, where magnifying lenses to ignite tinder were sold in a pharmacy, and Pliny the Elder’s “lens”, a glass globe filled with water, used to cauterize wounds. (Seneca wrote that it could be used to read letters “no matter how small or dim”). A convex lens used for forming a magnified image was described in the Book of Optics by Ibn al-Haytham in 1021. [verification needed] After the book was translated during the Latin translations of the 12th century, Roger Bacon described the properties of a magnifying glass in 13th-century England. This was followed by the development of eyeglasses in 13th-century Italy.
