High myopia lenses are relatively thick because of the high degree of myopia, and in order to avoid the light from the cut surface into the lens, and then refracted into the eye, which affects the visual function, it is recommended that patients with high myopia choose full-frame glasses, and try to be dark full-frame. Dark-colored frames can block some of the light and prevent light from refracting into the eye from the cut surface of the lens, which affects our vision. Of course, some people feel that wearing dark full-rimmed glasses will look particularly old-fashioned, so at least choose a half-rimmed glasses to block the light coming from above. At the same time, because of the high myopia lens periphery is thicker, relatively heavy weight of the lens, it is recommended that patients try to choose a smaller frame, and the entire frame weight light frame, so as to minimize the weight of the lens, reduce the pressure on the bridge of the nose.
