It is so bad that I checked many material for glasses, yet it seems that no one knows who invented glasses. Yet according to the known history, glasses were invented in northern Italy, in the late 1280s probably. The original inventor's identity is still a secret up to now. According to a medicine professior named Franciscus Redi, he had a paper wrote in 1289, in which the author said without the invention of glasses, he would be unable to read or write.
Benjamin Franklin, the American scientist, first invented bifocals in 1784, for himself is suffering from both myopia and presbyopia.
George Airy, the British astronomer, in 1827, invented the first lens for correcting astigmatism.
In 1727, the morden glasses forms, held by temples passing through ears, was developed by a British optician, named Edward Scarlett.
