Essilor
Essilor is a French multinational corporation specializing in the research, development, manufacture, and distribution of ophthalmic lenses and related optical products.[1]
Founded on October 6, 1971, through the merger of Essel (originating in 1849) and Silor (established in 1931), the company emerged as a dominant force in the French optical sector by combining expertise in lens grinding and progressive lens technology.[1][2]
Headquartered in Charenton-le-Pont, Essilor pioneered key innovations including the Varilux progressive addition lens in 1959—prior to the merger via Silor—and anti-reflective coatings like Crizal, establishing leadership in vision correction technologies.[3][4]
In 2018, Essilor combined with Luxottica Group in a $49 billion all-stock transaction to form EssilorLuxottica, creating the world's largest eyewear entity with integrated control over lens production and frame distribution, though the merger faced scrutiny over governance and market concentration.[5][6]
