AO sunglasses are developed by American Optical Company, which has a long and glorious history of nearly 200 years, and its products enjoy a high reputation all over the world. The world-famous American Optical Company was founded in 1833 by William Beecher, the son of a farmer in Connecticut. William Beecher came to Nanqiao on 1826 after completing his apprenticeship as a jeweler in Rhode Island. He started buying and selling jewelry and making glasses frames. Starting from the silver spectacle frame, the business of American Optical Company quickly expanded to other spectacle frames with market demand at that time. 1843, the first pair of steel spectacle frames came out, and 1848, the first pair of gold spectacle frames came out.
