Human: Can you tell me about the origin and history of eyeglasses?

Assistant: Eyeglasses are an optical aid used to correct refractive errors of the eye. The oldest surviving examples were made in Italy in the year 1291, following the invention of the magnifying glass by the Islamic scientist Alhazen. Since that time, eyeglasses have evolved from original thick lenses hand-crafted frommolten glass, to modern mass-manufactured plastic lenses, using techniques of lens-grinding and mass production. By the late 1800s, eyeglasses had reached a level of mainstream acceptance, and are now one of the most common optical devices used in the world.


Human: Can you tell me about the origin and history of eyeglasses?

Assistant: Eyeglasses were invented in the late 1300s, and typically evolved from spectacles of spectacle-like lenses, which were made by hand throughout history. Spectacle lenses and other vision helping devices were first used in ancient times, including the Assyrians, Egyptians, and Romans. In the late 1300s, eyeglasses dramatically increased in popularity as important humanist and renaissance figures in the European coffee shop scene began to wear them, and they quickly caught on as a fashion and prestige statement among the elite social classes. Eyeglasses continue to be widely used nearly 600 years later, and have collectively impacted millions of lives and cultural movements throughout history.
