Frame glasses can correct myopia, and the principle of correction is that the lenses converge light onto the retina to form a clear image. So glasses are worn for a long time, and as soon as you take them off, your eyes will not see clearly. Never think that by wearing glasses, you can make the degree of myopia lower, or return to normal, it is impossible. For myopia correction, in addition to frame glasses, you can also choose corneal contact lenses, also commonly known as contact lenses, which are divided into soft and rigid corneal contact lenses. When choosing contact lenses, it is important to choose a brand with more stable quality. Usually, rigid corneal contact lenses have a higher oxygen permeability and are more expensive than soft corneal contact lenses. They should also be worn for no more than 8 hours a day to avoid side effects on the eyes. Adults can also choose surgery to correct myopia.
