1. optometry
To be responsible, the optometry accepted by many people is incomplete and can even be described simply. Many optical shops have a lot of instruments, but that's just a display, and the last inspector didn't explain why you had to do those tests.
Select a frame.
I didn't know it was a study problem until I wore glasses twice. I need to choose glasses frames according to different face shapes, my own degrees, the distance between my eyes and the height of my nose ... This kind of glasses frame really achieves the desired comfort and appearance.
Don't blindly worship the brand. In fact, there are many inexpensive frames in China. Now it is found that brand photo frames are really advertising fees. I think it's very cost-effective to support domestic products.
Pick a shot
In fact, I am not very good at choosing lenses myself, because lenses are a bit metaphysical, just like burning headphones and lenses. However, the younger brother of educated youth glasses said that the lens should mainly suit himself, otherwise it would be uncomfortable to wear it again. So choose according to your own situation.
Important: If the clerk tells you what glasses are and what they do, you must ask the clerk for the outer packaging bag of glasses when you take them, because it is really important. I didn't know what I had prepared before, and I didn't know that it was our right to ask for the original lens packaging bag to check the documents until my little brother told me.
