Eyewear has become a steadily increasing market within the United States. The total amount of eyewear sold throughout the country has increased every year since 2009 in the four main categories: prescription (Rx) eyeglasses, plano sunglasses, over-the-counter (OTC) readers, and contact lenses. In 2014, 5.7 million units of plano sunglasses were sold online in the United States. In 2015, plano sunglasses sales generated 218 million U.S. dollars in the United States; with the total vision care market in the United States generating about 34.45 billion U.S. dollars.
Operating 4,628 retail stores throughout North America, Luxottica was the leading optical retailer in the United States with about 2.53 billion U.S. dollars worth of sales in 2015. Luxottica is actually the largest eyewear company in the world, responsible for such brands as Ray-Ban, Persol, Oakley, Burberry, Polo Ralph Lauren, Versace and many others. In 2015, the Luxottica Group had global sales that amounted to approximately 8.84 billion U.S. dollars.
The eyewear market will continue to grow as manufacturers continue to adhere to the constant demands and trends of the consumer. In January 2017, Italy's Luxottica and France's Essilor agreed a 46 billion euro merger to create a global eyewear powerhouse.
