Sales of plano sunglasses in the United States increased steadily between 2011 and 2016, and have since leveled off at around 4.2 billion dollars per year, with most of those sales being driven by sunglasses that cost more than 50 dollars a pair. As with most accessories, sunglasses have a diverse price range. While the vast majority of plano sunglasses are relatively affordable, some designer sunglasses can cost more than a new car.
The market for sunglasses is heavily concentrated, with the eyewear company Luxottica controlling a 39 percent share of the global market, more than the next largest eleven companies combined. Luxottica, an Italian company, generated almost 2.5 billion dollars in retail sales in the United States alone in 2017, and over nine billion euros in worldwide net sales. Essilor is another major player in the global sunglasses market, accounting for about eight percent of the total market.
As of 2018, the country with the highest per capita volume sales of sunglasses was Switzerland, at 0.7 sunglasses per person. The United States experienced per capita sunglasses sales of 0.6 units in that year. A 2016 survey found that about 83 percent of U.S. men wear sunglasses on a regular basis, compared to nearly 89 percent of U.S. women. In that same year, about 12 percent of Americans wore prescription sunglasses, up from 11.4 percent in 2013.
