1, weight, when comparing true and false GUCCI and DIOR, you will feel that the weight is very different. The fake one has no touch, but it is really textured.
2, GUCCI, DIOR glasses, more use Optyl, a patented material (epoxy resin). Its weight is 20~30% lighter than that of ordinary plastic frames. Compared with traditional thermoplastics, this material has an excellent polished surface, which will produce a unique magical color, but also more tough and not easy to deform. Optyl framework is easy to identify. Its legs and feet don't have metal rods used in ordinary plastic frames to increase their deformation resistance and strength, and the words Optyl will be printed on the bottom of the legs. The one-step molding and polishing process of this material requires a lot of equipment, so it is difficult to imitate it in China (fake temples usually have metal rods in them, but sometimes the temples are dark and may not be visible). SAFILO is very leading in the technology and quality of sunglasses lenses. Most lenses use multilayer filters, which can effectively block the harm of ultraviolet rays to the eyes. Some large-format lenses use ultra-thin microcrystalline technology on the lenses, which makes irregular lenses and frames perfectly combined. While providing the maximum visual field, it also avoids dizziness. It is difficult for consumers who have just come into contact with sunglasses to distinguish authenticity from the above two points.
A simpler identification method:
1. Starting from the end of the temple, the temples on the surface are made in Italy, with model code, color code and dimension. Don't buy without these.
2, for glasses with a broken nose, many people don't pay much attention to this, so counterfeiting is not very important, but it is easy to tell the truth! (including the material of the transparent plastic nose, the size and clarity of the logo inside)
3, hardware, this is just like the hardware on GUCCI and DIOR's bags. There is still a difference between imitation and authenticity.
4, sunglasses lens, a simple identification method can be placed in front of your eyes, through the lens to observe distant targets, such as window frames or door frames, and then move sunglasses up and down, front and back, the target should not swing and wave, you can also observe the tube image on the surface of sunglasses lens under fluorescent light, and move sunglasses to make the tube image appear in different parts of the lens, preferably without deformation. There should be no deviation in the color of the lens and no distortion in the color of the surrounding environment. Observe red, green and yellow objects before wearing sunglasses, and then wear sunglasses to observe the same object. The colors observed twice should not be cast off, otherwise the ability to identify traffic lights will be reduced.
