Step 1:Look and feel for seams on the plastic. All genuine Ray-Ban products are crafted from high-quality materials using the finest manufacturing processes. Notably, the plastic body of Ray-Ban sunglasses are cut from a single piece of acetate and are hand-polished. Because of this, you shouldn't be able to detect any nicks, rough spots, or especially seams on your glasses. These are after-products from cheap manufacturing processes and are dead giveaways that a pair of "Ray-Bans" aren't what they are being billed as.
Step 2:Retail Box. New Ray-Ban sunglasses are packaged in a branded retail box. Check for the print, colour and image quality of the logo. Also check that the logo and font matches that of used officially by Ray-Ban. Be aware that genuine packaging can accompany counterfeit sunglasses.
Step 3:Check for flushness of the temple logo. Take off your glasses and look at them from the side. There should be a cursive "Ray-Ban" logo on the temple portion of the glasses. Look at this closely ¡ª it should be cleanly, professionally attached, sitting more or less flush against the "arm" of the glasses. If the logo itself seems poorly-made or stuck onto the side of the glasses with glue or pins, your glasses are probably not genuine.
