Purchasing optical, people should choose the normal manufacturers and the productions which are produced by the certain famous enterprise. Because fake products and low-qualified ones usually haven’t qualified the inspection, and their quality can not be guaranteed, Such glasses not only can not protect our eyes, but also do a great harm to our eyes when wearing for a long time. Then how to distinguish the ture and false famous band sunglasses?

In fact, it's quite easy. The optical eyeglasses are different from fashion and bags which has their own type and color code. These codes are set by manufacturers. If the style and the model of the product do not match the product model on the authoritative website, of course it is the counterfeit. Through this way, those self-prepared types of fakes can't hold water and are forced to let the cat out of the bag. There is another possibility that bad-intentioned sellers have taken the genuine pictures of others as their own, But the products that buyers receive are similar but fake ones. So, it is better to select sellers having picures in kind or better public praises.

Another way to distinguish the genuine from the fake is to check whether the sellers provide the certificate of the sunglasses. There are lots of famous glass brands in Italy, and there are lots of glass producing companies known by the world, too. Safilo Group is the biggest glasses manufacturer in the world and its headquarter is located in Italia. All the top class famous brand sunglasses in general are their products. Brand-name glasses such as Burberry, Dior, Gucci, Armani, Valentino, and YSL are all manufactured by Safilo. They control the distribution channel strictly and don't allow productions of being wholesaled at random.

In the United States, only the national qualifications related shops can purchase goods from the safio, and there will be professinal persons supervising sellers and patent stores, not allowing to take hostile competition by reducing prices. Each pair of Safilo optical glasses will accompany by a certification when leaving the factory, so we should say that the ones which have been made by Safilo without certificates are fake ones. Finally, it absolutely does not mean that expensive items are genuine ones, people should also abstain from being seized by someon due to such psychology.
