"Bausch & Lomb (since 2010 stylized as Bausch + Lomb) is an American-Canadian eye health products company based in Vaughan, Ontario, Canada. It is one of the world's largest suppliers of contact lenses, lens care products, pharmaceuticals, intraocular lenses, and other eye surgery products. The company was founded in Rochester, New York, in 1853 by optician John Bausch and cabinet maker turned financial backer Henry Lomb, initially producing monacles. By 1861, their operation had expanded to manufacturing vulcanite rubber eyeglass frames and other precision vision products. In 1876, Ernst Gundlach joined the company as it began to manufacture microscopes. The company also produced photographic lenses (1883), spectacle lenses (1889), microtomes (1890), binoculars and telescopes (1893). From 1892 in cooperation with Zeiss in Germany, the company produced optical lenses. In this manner, at the end of the 19th century, the product range included eyeglasses, microscopes and binoculars, as well as projectors, camera lenses and camera diaphragms. The company produced the first optical-quality glass in America during the early to mid-1900s. By the year 1903 the company began manufacturing microscopes, binoculars, and camera shutters. The further development of the firm was affected by political events. Because of the World Wars and the consequent need for optical instruments such as field glasses, range finders, camera lenses, binocular telescopes, searchlight mirrors, torpedo tube sights, and periscopes, the product range could be considerably broadened. In the 1930s, military products represented 70% of total production. The Ray-Ban brand of sunglasses was developed for pilots in 1936. At a time when the cinema was being superseded by television, Bausch & Lomb developed improved optics for the CinemaScope process, which popularized the film-based anamorphic format and led most cinemas to double the widths of their screens. In 1965 Bausch & Lomb acquired the patent for the hydrogel contact lenses created by Czech scientists Otto Wichterle and Drahoslav Lím. In 1971, after three years of development work, two years for the medical approval by the United States Food and Drug Administration and an investment of three million USD, Bausch + Lomb launched contact lenses made of Poly-HEMA. In the 1970s, the company was a major producer of spectrophotometers for the dye and chemical business. A massive restructuring of the company began in the mid-1980s. In 1997, as a result of a series of company acquisitions, the division for the manufacture of surgical products was established. The Ray-Ban brand was sold in 1999 to the Italian Luxottica Group. Since then, Bausch & Lomb has developed into a globally operating company which is one of the largest producers of contact lenses." (Source: wikipedia)
