Mid- to high-end: Danyang, Taizhou, Wenzhou. Danyang should be the largest eyewear industry belt at present. The world's second largest eyewear factory, the Safilo factory, is located in this industry belt! If you usually choose 300-600 models when fitting glasses in physical stores, you can take a look at these places of origin. This is the source of glasses with huge profits in street physical stores.

High-end: Henggang, Shenzhen. In the 1990s, a powerful Hong Kong eyewear factory came to Henggang to set up a factory, mainly to help European and American big brands. If you want to buy the same models of various big brands, if the place of origin is Shenzhen, the quality is generally acceptable.
