Who are Chanel sunglasses competitors?

Chanel is a Luxottica brand, so their competitors are other manufacturers like Safilo, Viva, REM Eyewear, etc. A lot of the name brands most people consider Chanel competetion are also owned by Luxottica--i.e., Versace, Bulgari, Oakley, Paul Smith, Oliver Peoples, Prada, Gucci. Of course, Luxottica only owns the eyewear rights--not the brands and designers themselves. =)
