The company makes most of those brands under license, working closely with designers at the relevant fashion houses. But it owns several brands itself, including Ray-Ban, Oakley, Oliver Peoples and REVO. [...] In many cases, the same company is also selling you the glasses. Luxottica also owns LensCrafters, Pearle Vision and Sunglass Hut. This is extreme vertical integration. The eye doctor telling you that you need a new pair of glasses, the sales people helping you choose them and the people who design and make the glasses all work for the same company.
