Invention of eyeglasses
The 'Glasses Apostle' by
Conrad von Soest (1403)
The first eyeglasses were made in Italy at about 1286 originally consisting of thin pieces of glass which were placed directly onto the eye ball. According to a sermon delivered on February 23, 1306, by the Dominican friar
Giordano da Pisa (ca. 1255–1311): "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." Giordano's colleague Friar
Alessandro della Spina of Pisa (d. 1313) was soon making eyeglasses. The
Ancient Chronicle of the Dominican Monastery of St. Catherine in Pisa records: "Eyeglasses, having first been made by someone else, who was unwilling to share them, he [Spina] made them and shared them with everyone with a cheerful and willing heart." By 1301, there were guild regulations in Venice governing the sale of eyeglasses.
In 1907, Professor
Berthold Laufer, who was a
German-American anthropologist, stated in his history of spectacles that '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'. The German word
brille (eyeglasses) is derived from Sanskrit
vaidurya. But other sources show the the German word brille was derived from the beryl: "Medieval Latin berillus also was applied to any precious stone of a pale green color, to fine crystal, and to eyeglasses (the first spectacle lenses may have been made of beryl), hence German Brille "spectacles," from Middle High German berille "beryl," and French besicles (plural) "spectacles," altered 14c. from Old French bericle."
However, Joseph Needham showed that the mention of spectacles in the manuscript Laufer used to justify the prior invention of them in Asia did not exist in older versions of that manuscript, and the reference to them in later versions was added during the Ming dynasty — after eyeglasses had been invented in Europe.
Although there have been claims that
Salvino degli Armati of Florence invented eyeglasses, these claims have been exposed as hoaxes. Furthermore, although there have been claims that
Marco Polo encountered eyeglasses during his travels in China in the 13th century, no such statement appears in his accounts. Indeed, the earliest mentions of eyeglasses in China occur in the 15th century and those Chinese sources state that eyeglasses were imported.

The earliest pictorial evidence for the use of eyeglasses is
Tommaso da Modena's 1352 portrait of the cardinal Hugh de Provence reading in a
scriptorium. Another early example would be a depiction of eyeglasses found north of the
Alps in an altarpiece of the church of
Bad Wildungen,
Germany, in 1403.
These early spectacles had
convex lenses that could correct both
hyperopia (farsightedness), and the
presbyopia that commonly develops as a symptom of
aging. It was not until 1604 that
Johannes Kepler published the first correct explanation as to why convex and concave lenses could correct presbyopia and myopia.
and if someday they'll bring some hardcore shit on chp, that would again be fine by me. this whole situation can be summarized by this turkish saying: bıldır yediğin hurmalar gelir g.tünü tırmalar
