Good day, Am new to Oakley, and recently I purchased Carbon Blade Scuderia Ferrari, Previously am using Ray-ban G-15 tech, as i like carbon fiber, G-15 lens are great, easy to clean with any cloth, very clear and my last one i use for everyday for five year without any scratch that why i love it. But last time i search for carbon fiber sunglasses i found Oakley Carbon Blade and i like it, without looking a price tag i purchase it, but its a bit expensive, but i feel it worth the price, and please help me to verify if the one I purchased is authentic Oakley. as i don't know what to look for, it feels legit, looks legit and I want to us opinion of the experts. Hope you can help me. Thanks and am start loving Oakley, but it needs a lot of care unlike my previous one.
