Some people spend tens of yuan to buy a pair of eyewear , some people spend thousands of yuan to buy a pair of glasses, and some even tens of thousands of yuan. Why do the prices of glasses vary so much? Based on the experience accumulated in our daily life, we can first think of the first factor: the quality is different. The same product, even if the same material is used, the difference in production process and the ability to control details will still lead to differences in quality. Good quality glasses are naturally more expensive. In addition to quality reasons, what other reasons?

The amount of heart shift is what really determines the thickness in essence. Myopic lenses are thin at the center and thick at the edges. So the more you get to the edge, the thicker you get. In theory, the closer your interpupillary distance is to the frame's inte
