There are many ways to tell if a pair of Oakley sunglasses is real or not. Genuine Oakleys have the Oakley logo on the arm with the letter “O” embedded into the frame. They come in either a hard case or soft pouch that also has the logo on it.
If the logo appears on the lens, it is etched into it and not printed. There is also a certificate of authenticity or warranty card included with the sunglasses. Oakley recommends that customers call Oakley customer care and send a picture of the sunglasses to find out if they are real or counterfeit. Customers can also visit an Oakley store or authorized Oakley dealer for confirmation.
