The cost of glasses is only a dozen yuan, but selling them to you will cost hundreds or even thousands. This is a saying that many people have heard. Is it really true? What pitfalls should you pay attention to when buying glasses? In order to answer these questions, we asked practitioners from the optical industry: from the profit model of optical shops, to choosing domestic products, or a series of issues such as lenses, frame selection, where to go for optometry, and whether it is reliable to buy glasses online. Hope it helps everyone~
