Aviators of the US army played a major role during the war years. As the airmen flew at great heights, they started getting headaches and other ailments due to the intensity of the sky colours. US Army Air Corps Colonel John A. Macready commissioned a New York-based medical equipment manufacturer Bausch & Lomb, to create aviation sunglasses that would get rid of these problems.
Bausch & Lomb developed a sunglass with plastic frame and green lenses that solved the problem without affecting visibility. It was known as Anti-Glare. This happened in 1929 and a year later, it was patented as Ray-Ban after redesigning it with a metal frame. Each model that was released later became popular in no time. After the war, these sunglasses were made available to the public. In 1999, Bausch & Lomb sold the brand to Luxottica Group, an Italian eyewear conglomerate.
