1． There are faint RB letters on the left eye lens, which are laser engraved. Some lay buyers sometimes think it is a defect in the glass

2. The nose bridge is made of 14K gold foil with English RAYBAN on it. The fake one is made of copper and will turn green soon

3. The frame is made of Ferrari engine gear alloy. It is strong and durable. The material is the same inside and outside. Now it is fake. They are all steel nickel alloy, coated with the U.S. Air Force Institute of Radiation Energy Science and Technology, FN high-tech coating, blocking 97% of space rays and 94.8% of sunlight diffuse reflection

Quick (non-instrument test) Some tips for distinguishing genuine and fake RayBans are as follows:

1. The uppermost horizontal bar at the nose bridge of the frame is engraved with B&L Ray-Ban USA, and the bottom is engraved with B&L Ray-Ban 62□14. The engraving of the genuine product should be milled and pressed by precision molds. Even if you look at it with a magnifying glass, there is no rough feeling and it gives a delicate impression. The intaglio engraving on the imitation Lei Peng is relatively rough, the text is skewed, the indented parts are of varying depths, and the overall lack of sophistication.

2. The two frosted BL logos recessed on both sides of the lens are probably made by cutting and polishing using laser technology. They feel smooth and wordless when touched by hand, but the fonts are clear and beautiful, although they are extremely recessed. It is shallow, but the edges of the letters are sharp and angular. I have seen two types of imitations of this logo: one is a poor imitation, which is purely printed on transparent material using silk screen printing technology. If you touch it carefully with your hands, it will feel raised; the other is a poor imitation. The successful one also uses laser frosting technology, but the craftsmanship is poor. When compared with the original product, the authenticity is immediately obvious.

3. The white Ray on the lens of the right eye. The Ban logo is printed by silk screen technology. The genuine product is very wear-resistant. At least none of the lenses I have used have obvious scratches. I bought them more than 20 years ago and used the white Ray on the lenses that I have worn for more than ten years. The silk screen logo is still clear and beautiful. But the white Ray on the fake lenses. Ban marks will fall off after a period of normal use and become mottled.

4. The metal support inside the soft transparent nose pad has a stamped BL exquisite logo.

5. The black genuine frames are made of enamel, and the gold ones are made of metal plating. Both of them are not easy to peel off the baking layer and coating. The gold color of imitation products will become lighter and oxidized after short-term use.

6. Authenticity guarantee, trademark gold medal, and folding product listings are complete. There is a one-year warranty period. The product grade and warranty card number are indicated in the warranty card, as well as the warranty obligations of agents such as Bausch & Lomb. However, this is easy to fake. Many merchants collect genuine warranty certificates and trademark gold medals. , folding product listings and other information are then sold together with the imitations.

7. Labeling is authentic. Not all Ray-Ban sunglasses have labels, but for example, Ray-Ban’s classic G15 lenses, B15 lenses, etc. all appear with gold labels, and the labels are shiny; If it is a polarized lens, it will have a red label. Imitation: The gold sticker is dull and the polarizer sticker is attached to the regular model.
