Dude, it's actually very simple. If you don't trust the optical shop, then go to the hospital for optometry, and then go to the optical shop with an optometry sheet to get glasses. Then there is the price of glasses, because I make my own glasses and I don't know how to say it. Anyway, the lens should choose a well-known domestic brand. Don't listen to people bluffing about their functions. Below 400 degrees, the refractive index of 1.56 should be selected. Above 400, you can choose 1.60 refractive index. If the economy is tight, you can also choose a lens with a refractive index of 1.56 below 600 degrees, but choose a smaller frame, otherwise it will be too thick when viewed from the side. This is also related to your pupillary distance, which is small, so the outer edge will be thicker because the center of the lens is close to the bridge of the nose. At least you choose Hong Chen in China, and Wan Xin is the best choice. You can check Baidu, the top ten brands of domestic lenses.

Don't come when you see your advertisement. My website is hard to tell you.

I hope I can help you. After all, my parents work hard to earn money, so I can save it.
