How can I tell if Essilor lenses are genuine?

How can I tell if Essilor lenses are genuine? Nowadays, many people buy a pair of glasses equipped with Essilor lenses in an optical store or online glasses mall, and want to know whether the glasses they get are Essilor lenses, for fear that the merchant will change their bags. Let's introduce to you: the authenticity of Essilor lenses. How can I tell if Essilor lenses are genuine? 1. Anti-counterfeiting logo of Essilor lenses All Diamond Crystal A2 and Diamond Crystal Zhijie film layers have fog marks, when Essilor lenses have not wiped off the protective film, take a breath, and the word "Crizal" is displayed on the lens. However, aquamarine and white crystal lenses cannot be verified using this method because they do not have fog display markings. Secondly, in order not to affect the effective visual area, the fog display marks are all outside the radius of the optical center of the lens 30mm, so if the size of the lens circle is too small, the amount of displacement due to the interpupillary distance is too large, or the astigmatism axis is limited, the fog display may not be visible or only partially visible. The reason is that there is fog and it appears that the part of the lens has been cut off by the edging machine. 2. Verify through the anti-counterfeiting code on the lens packaging Since the second quarter of 2012, Essilor has sold lens packaging bags with anti-counterfeiting labels, and the packaging bags of each lens clearly write the type, power and other relevant data of the lens, and there is a 16-digit anti-counterfeiting label on the back of the bag, which we can verify on the official website of Essilor according to this anti-counterfeiting code ( http://www.essilorchina.com/validproductcode_new.aspx) The authenticity of the product, it is worth noting that the anti-counterfeiting code is only for one verification. If the number of times is exceeded, the anti-counterfeiting code will be prompted to exceed the specified number of queries. 3. Look at the warranty card of the lens See if there is a warranty card, all Essilor lenses have a warranty card, in the original packaging, and the warranty card of different series of lenses is different. The warranty card is the most effective way, any merchant will issue a warranty card when selling genuine Essilor products, and each pair of lenses is very free to have a warranty card, which is not easy to forge, and its validity is more credible than the packaging bag. 3. Observe the color of the lens coating From the point of view, the coating of Essilor lenses is yellow-green and slightly greenish, while other lenses cannot be imitated, and can be judged by comparison method. Compare your lenses to other lenses that are not Essilor, and the precious coating is different. Small
