The company has been criticised for the high price of its brand-name glasses, such as Ray-Ban, Oakley, and several others. A 2012 "60 Minutes" segment focused on whether the company's extensive holdings in the industry were used to keep prices high. Luxottica owns not only a large portfolio of brands (over a dozen) such as Ray-Ban and Oakley but also retailers such as Sunglass Hut and Oliver Peoples, the optical departments at Target and Sears, as well as key eye insurance groups including the second largest glasses insurance firm in the US. It has been accused of operating a complete monopoly on the optical industry and overcharging for its products; for example, temporarily dropping then-competitor Oakley from its frame design list, then, when the company stock crashed, purchasing the company, then increasing the prices of its Ray-Ban sunglasses. In addition, it has been argued that, by owning the vision insurance company EyeMed, it also controls part of the buyers' market as well.
