How should I find out whether my sunglasses are orignal or duplicate?

[Scobey]

I have a pair Rayban Sunglasses which was given by my friend as gift. Is there any way to find out whether they are real or fake ?

Compare photos of the sunglasses to photos from the designer's official website. If you notice any variations between the two, the sunglasses in question are not authentic.

For Rayban Sunglasses, you can check whether it is made in Italy .If not ,congratulation, you got the fake one . Secondly ,check the logo .The real ray-ban Brand have "Ray-Ban" written in white on the right lens ( Polarized versions have "Ray-Ban P" ). on the Left lens they have "RB" Engraved. This left lens engraving is the hardest to copy. Then study the label to see if there are any misspelled words . Lastly check the case . The craftsmanship of the case should be delicate and durable .Also it should come with Rayban's logo
