Content:   The American scientist Benjamin Franklin, who suffered from both myopia and presbyopia, invented bifocals. Historians have from time to time produced evidence to suggest that others may have preceded him in the invention; however, a correspondence between George Whatley and John Fenno, editor of The Gazette of the United States, suggested that Franklin had indeed invented bifocals, and perhaps 50 years earlier than had been originally thought. The first lenses for correcting astigmatism were designed by the British astronomer George Airy in 1825. Over time, the construction of frames for glasses also evolved. Early eyepieces were designed to be either held in place by hand or by exerting pressure on the nose (pince-nez). Girolamo Savonarola suggested that

As the stones were experimented with, it was slowly understood that shallower lenses magnified more effectively. Around 1286, possibly in Pisa, Italy, the first pair of eyeglasses were made, although it is unclear who the inventor was. The earliest known working telescopes were the refracting telescopes that appeared in the Netherlands in 1608. Their inventor is unknown: Hans Lippershey applied for the first patent that year followed by a patent application by Jacob Metius of Alkmaar two weeks

Content:  Historians have produced some evidence to suggest that others may have come before him in the invention; however, a correspondence between George Whatley and John Fenno, editor of the Gazette of the United States, suggested that Franklin had indeed invented bifocals, and perhaps 50 years earlier than had been originally thought. Despite this, the College of Optometrists concluded: Since many inventions are developed independently by more than one person, it is possible that the invention of bifocals may have been such a case. John Isaac Hawkins, the inventor of trifocal lenses, coined the term bifocals in 1824 and credited Benjamin Franklin. In 1955, Irving Rips of Younger Optics created the first seamless or "invisible" bifocal, a precursor to progressive lenses. This followed Howard D. Beach's 1946 work in "blended lenses", O'Conner's  "Ultex" lens in 1910, and Isaac Schnaitmann's single-piece bifocal lens in 1837.

People may first have cut glass for eyeglasses from glass panes, but in time others began grinding smooth pieces of glass into convex lenses and producing proper eyeglasses. The art of grinding eyeglasses was known almost 600 years ago. A couple of hundred years later, the children of a certain eyeglass grinder, while playing with lenses, placed one in front of another and found that they could see better through two lenses than through one. They informed their father about this curious occurrence, and he began producing tubes with two magnifying

The first wearable eyeglasses were invented in Italy around 1286. This was the start of the optical industry of grinding and polishing lenses for these "spectacles", first in Venice and Florence in the thirteenth century, and later in the spectacle making centres in both the Netherlands and Germany. Spectacle makers created improved types of lenses for the correction of vision based more on empirical knowledge gained from observing the effects of the lenses rather than using the rudimentary optical theory of

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.

Content:  Grosseteste's treatise De iride ("On the Rainbow"), written between 1220 and 1235, mentions using optics to "read the smallest letters at incredible distances". A few years later in 1262, Roger Bacon is also known to have written on the magnifying properties of lenses. The development of the first eyeglasses took place in northern Italy in the second half of the 13th century. Independently of the development of optical lenses, some cultures developed "sunglasses" for eye protection, without any corrective properties. For example, flat panes of smoky quartz were used in 12th-century China, and the Inuit have used snow goggles for eye protection.

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.

In 1971 Rishi Agarwal, in an article in the British Journal of Ophthalmology, states that Vyasatirtha was observed in possession of a pair of glasses in the 1520s, he argues that it "is, therefore, most likely that the use of lenses reached Europe via the Arabs, as did Hindu mathematics and the ophthalmological works of the ancient Hindu surgeon Sushruta", but all dates are given well after the existence of eyeglasses in Italy was established, and there had been significant shipments of eyeglasses from Italy to the Middle East, with one shipment as large as 24,000 glasses.

Content:  Jerome Jay Wolken (March 28, 1917 &ndash; May 10, 1999) was an American biophysicist who used his research in vision in deep sea creatures to develop a kind of eyeglasses that used specially designed lenses to gather more light, which provided vision to some people who were legally blind.

Question: who invented the glasses that give sight to the blind?
