Luxottica, an Italian sunglass manufacturer, owns 60% of all sunglass sales has a yearly revenue of $10.74 billion. This company owns many sunglass distributors, some of which include: Ray Ban, REVO, Valentino, Oakley, and Coach.
I think this is extremely unreasonable, because sunglass prices have shot up more that 200% in the last decade. I personally would not buy from Luxottica’s distributors due to the unknown quality that they provide. Why even spend the money on Luxotica’s brands? They are almost the same price but with a shockingly difference in lens quality.
