The Choice of Lens Technology is Clear

Sep 11, 2018 | Uncategorized

Lens technology has evolved significantly since the early days of the reading stone. Reading stones were developed in the 9th century, developed during the process of converting sand into glass. A hemispherical lens placed on top of text to magnify letters, these stones were among the earliest applications of lens technology.

In the early 14th century, Dominican friar Giordano da Pisa wrote “It is not yet twenty years since there was found the art of making eyeglasses, which make for good vision. And it is so short a time that this new art, never before extant, was discovered. I saw the one who first discovered and practiced it, and I talked to him.” Friar Alessandro della Spina of Pisa, a colleague of Giordano, was soon making eyeglasses for the public, and not only for personal use.

By 1301, there were guild regulations in Venice governing the sale of eyeglasses, as the practice began to take hold. Early frames consisted of two magnifying glasses riveted together by the handles, so that they could grip the nose. The earliest surviving examples of these “rivet spectacles” were found under the floorboards at Kloster Wienhausen, a convent in Germany dating back to the 1400s.

Certain historians believe that the invention of the bifocal, necessary for sufferers of both myopia and presbyopia, preceded Benjamin Franklin. However, correspondence between George Whatley (a friend of Benjamin Franklin) and John Fenno (editor, The Gazette of the United States) suggests that not only had Franklin invented bifocals, but had invented them 50 years earlier than originally thought. Originally, bifocals were designed with the most convex lenses in the lower half of the frame, and the least convex lenses on the upper. Two separate lenses were cut in half, and combined. This led to a number of complications, and rendered the lenses fragile.
