Sunglasses were used in the 12th century or possible earlier in China. But in the early 1900s, the use of sunglasses become more widespread, especially among Hollywood movie stars.
Inexpensive mass-production of sunglasses started in 1929 when Sam Foster introduced them to America. Foster sold his sunglasses on the beaches of Atlantic City, New Jersey under the name Foster Grant from a Woolworth on the Boardwalk. These sunglasses were made to protect people's eyes from the sun's rays.
Polarized sunglasses first became available in 1936, when Edwin H. Land began using his patented Polaroid filter when making sunglasses.
Sunglasses even played a significant role during the World War II, when Ray Ban created anti-glare aviator style sunglasses, using polarization. Ray-Ban Aviator sunglasses became popular with the celebrities and the community in 1937 when they started to be sold for the public.
Today, sunglasses with UV protection has almost become an industry standard, and there are a lot of tints available for sunglasses, and sunglasses styles are changing every year.
