Which brand of myopia lens is better, imported or domestic? Tell me the reason, and recommend the frames by the way ... Thank you. I belong to high myopia …

High myopia, you can choose high refractive index lenses, and the glasses will be relatively thinner and lighter. The choice of import or domestic production depends on one's own economic conditions and psychological needs. Glasses frames should be made of light metal products (titanium, cobalt-chromium alloy) as far as possible. The advantages of this kind of glasses are: lightweight and not easy to deform.
