Most brands have security codes on the frames. Brand sunglasses usually have their own anti-counterfeiting mark, or anti-counterfeiting code, and some also have anti-counterfeiting phone numbers, such as Suboshang sunglasses. If they are genuine, each pair will have a unique anti-counterfeiting code, just like a person's ID card, with the words on the temples and The trademark is also very clear and neat and is not easy to wear. Another important anti-counterfeiting sign is that as long as you breathe into the lens, the trademark of four swans will appear. These are usually the ways to tell the authenticity of sunglasses. I hope this helps you.

When purchasing brand glasses, please choose formal channels.

If you like trendy brand style, I recommend SUPER SUNG glasses or JD.com’s “SUPER SUNG flagship store”
