Optometry
History

Optometric history is tied to the development of

The history of optometry can be traced back to the early studies on optics and image formation by the eye. The origins of optical science (optics, as taught in a basic physics class) date back a few thousand years as evidence of the existence of lenses for decoration has been found in Greece and the Netherlands.

It is unknown when the first spectacles were made. The British scientist and historian Sir Joseph Needham, in his Science and Civilization in China, reported the earliest mention of spectacles was in Venetian guild regulations c. 1300. He suggested that the occasional claim that spectacles were invented in China may have come from a paper by German-American anthropologist Berthold Laufer. Per Needham, the paper by Laufer had many inconsistencies, and that the references in the document used by Laufer were not in the original copies but added during the Ming dynasty. Early Chinese sources mention the eyeglasses were imported.

Research by David A. Goss in the United States shows they may have originated in the late 13th century in Italy as stated in a manuscript from 1305 where a monk from Pisa named Rivalto stated "It is not yet 20 years since there was discovered the art of making eyeglasses". Spectacles were manufactured in Italy, Germany, and the Netherlands by 1300. Needham stated spectacles were first made shortly after 1286.

In 1907, Laufer stated in his history of spectacles 'the opinion that spectacles originated in India is of the greatest probability and that spectacles must have been known in India earlier than in Europe'. However, as already mentioned, Joseph Needham showed that the references Laufer cited were not in the older and best versions of the document Laufer used, leaving his claims unsupported.

In Sri Lanka, it is well-documented that during the reign of King Bhuvanekabahu the IV (AD 1346 – 1353) of the Gampola period the ancient tradition of optical lens making with a natural stone called Diyatarippu was given royal patronage. A few of the craftsmen still live and practice in the original hamlet given to the exponents of the craft by royal decree. But the date of King Bhuvanekabahu is decades after the mention of spectacles in the Venetian guild regulations and after the 1306 sermon by Dominican friar Giordano da Pisa, where da Pisa said the invention of spectacles was both recent and that he had personally met the inventor

The German word brille (eyeglasses) is derived from Sanskrit vaidurya. Etymologically, brille is derived from beryl, Latin beryllus, from Greek beryllos, from Prakrit verulia, veluriya, from Sanskrit vaidurya, of Dravidian origin from the city of Velur (modern Belur). Medieval Latin berillus was also applied to eyeglasses, hence German brille, from Middle High German berille, and French besicles (plural) spectacles, altered from old French bericle.

Benito Daza de Valdes published the first full book on opticians in 1623, where he mentioned the use and fitting of eyeglasses. In 1692, William Molyneux wrote a book on optics and lenses where he stated his ideas on myopia and problems related to close-up vision. The scientists Claudius Ptolemy and Johannes Kepler also contributed to the creation of optometry. Kepler discovered how the retina in the eye creates vision. From 1773 until around 1829, Thomas Young discovered the disability of astigmatism and it was George Biddell Airy who designed glasses to correct that problem that included sphero-cylindrical lens.

Although the term optometer appeared in the 1759 book A Treatise on the Eye: The Manner and Phenomena of Vision by Scottish physician William Porterfield, it was not until the early twentieth century in the United States and Australia that "optometry" began to be used to describe the profession. By the early twenty-first century, however, marking the distinction with dispensing opticians, it had become the internationally accepted term.
