1) It is unknown who was the first to design wearable glasses. The Romans, on the other hand, were the first to use glass to improve their capacity to view small text, inventing miniature magnifying glasses with spheres. During the 13th century, the first wearing glasses were discovered in Italy.
2) The “reading stone” is a piece of glass sliced in half that magnifies a text when placed on it. It was invented in the 9th century. The reading stone is thought to have been developed by Abbas ibn Firnas. All of them were early attempts to enlarge objects and improve vision.
3) A portrait of a bespectacled cardinal who lived before eyeglasses were developed appears in a fourteenth-century fresco painted by Tommaso da Modena in Treviso, Italy.
4) In 1888, Fick and Paris optician Edouard Kalt developed and installed the first glass contact lenses for vision correction. Glass contact lenses were heavy and covered the full front surface of the eye, including the "white" of the eye, in the early days (the sclera).
5) Polycarbonate or Trivex lenses are usually the best choice for eyeglasses, sunglasses, and sports eyewear where eye safety is an issue. They also provide 100 percent UV protection and are up to ten times more impact-resistant than plastic or glass lenses.
6) Edward Scarlett (1688–1743) was an English optician and instrument manufacturer who, in 1727, designed the first eyeglass frame incorporating earhooks.
7) Presbyopia, a condition Franklin suffered from, is usually treated using bifocals. Franklin wrote to his friend George Whatley in August 1784 that he was "glad in the development of double glasses, which serve for distant as well as near objects, make my eyes as useful to me as ever."
8) Because toric contact lenses are specifically intended to manage astigmatism, they are generally the best option for contact lens wearers with the condition. A toric lens's unique shape produces variable refractive, or focusing, powers, which can assist correct corneal or lenticular astigmatism.
9) In his book ‘De iride,' written about 1220-1235, Robert Grosseteste mentioned the use of optics. Optics was addressed in the context of little letters having to be read from a considerable distance away, necessitating the use of a vision aid.
10) It was originally dubbed the "devil's tool." Meanwhile, two-lens spectacles arose, and concave lens eyeglasses for myopia (nearsightedness) were invented in the 16th century.
