when was the first pair of glasses invented
Glasses The first eyeglasses were made in Northern Italy, most likely in Pisa, by about 1290: In a sermon delivered on 23 February 1306, the Dominican friar Giordano da Pisa (ca. 1255–1311) 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."[20]

Antonie van Leeuwenhoek By placing the middle of a small rod of soda lime glass in a hot flame, van Leeuwenhoek could pull the hot section apart to create two long whiskers of glass. Then, by reinserting the end of one whisker into the flame, he could create a very small, high-quality glass sphere. These spheres became the lenses of his microscopes, with the smallest spheres providing the highest magnifications.[14]
Daguerreotype Invented by Louis-Jacques-MandÃ© Daguerre and introduced worldwide in 1839,[4][5][6] daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. During the past few decades, there has been a small revival of daguerreotypy among photographers interested in making artistic use of early photographic processes.
