Most brands of 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 human’s. The words and trademarks on the ID card and temples are also very clear and neat and not easy to wear. Another important anti-counterfeiting sign is that as long as you breathe into the lens, the four swan trademarks 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”
