The origin of modern eyeglasses

The origins of modern glasses can be traced back more than 1,000 years. In the Middle Ages, the reading stones used by monks were glass spheres, sometimes filled with water and placed on objects to magnify them.Glassblowers in Italy created reading stones, similar to modern hand-held magnifying glasses. The reading stone can be placed on the wearer's nose or in front of the face. Later, Spanish craftsmen built the first cobra-framed temple in the 17th century. They tie ribbons or strings to the frames and tie them around the user's ear.

In the 18th century, Edward Scarlett created the first wearable glasses, providing more comfort for eyewear wearers. These early glasses had glass lenses embedded in heavy frames made of wood, lead, or copper. Natural materials of leather, bone, and horn were later used to make the frames. In the early seventeenth century, lighter steel frames were invented. As eyewear continued to evolve and prescription accuracy improved, the trend for eyewear to become more fashionable began. In the 18th century, bifocal lenses appeared, making it possible to correct upper myopia and lower presbyopia. Later glasses were designed to be fixed by a ribbon or by applying pressure to the bridge of the nose. In the 1980s, plastic lenses were introduced, providing a more durable alternative to glass lenses. Ultimately, the glasses used today are the result of centuries of technological and intellectual advances.
