Dolce And Gabbana Glasses

I recently bought a pair of prescription eyeglasses and I want to know how to tell if they are real.

They should have a small number of series on somewhere ... Are Dolce & Gabanna? or most popular, the line of entry-level D & G Dolce & Gabanna? One way is to make sure D & G for shop or dealer. Do they say "Made in China (most of D & G) or" Made in Italy (Dolce & Gabbana)

Good luck
