A concise historical narrative of NAICS Code 333310-03 covering global milestones and recent developments within the United States.

• The manufacturing of magnifying glasses dates back to the 13th century when the first reading stones were invented in Italy. These were small glass lenses that were used to magnify text and were held by hand. In the 16th century, the first eyeglasses were invented, which were made of two lenses held together by a frame. The first microscope was invented in the 17th century, which used a combination of lenses to magnify objects. In the 19th century, the first binocular microscope was invented, which allowed for greater magnification and better viewing of specimens. In recent history, the manufacturing of magnifying glasses has become more automated and efficient, with the use of computer-aided design and manufacturing (CAD/CAM) technology. The industry has also seen advancements in the materials used to make magnifying glasses, with the use of lightweight and durable materials such as polycarbonate and acrylic. In the United States, the manufacturing of magnifying glasses began in the late 19th century, with the establishment of companies such as Bausch & Lomb and American Optical. During World War II, the demand for magnifying glasses increased, as they were used in military applications such as map reading and bomb disposal. In the post-war period, the industry continued to grow, with the development of new products such as magnifying lamps and magnifying mirrors. In recent years, the industry has faced challenges from the increasing use of digital devices, which have reduced the demand for traditional magnifying glasses. However, the industry has responded by developing new products such as magnifying glasses with built-in LED lights and magnifying glasses for use with smartphones and tablets.
