When myopia worsens, it progresses to high myopia and ultra-myopia, and is specially designed for use by people wearing high myopia glasses. In general, people wearing glasses with high myopia recommend a small lens frame.This is because if the size of the glasses lens is large, it is not only heavy, but also the thickness outside the lens increases, which can make the object look curved. Therefore, the more myopia, the smaller the size of the glasses lens is, but the larger the face, the more problematic it is.This is because the size of the glasses lens is small, so they have no choice but to endure the opening of the glasses leg. Therefore, these are specially designed glasses with 6 grams of light glasses by selecting high myopia glasses and large glasses wearers.By minimizing the effect of abnormal size through free lens processing for the entire size as well as the distance between pupils, it is easy to produce high myopia and big-size glasses during vision correction.
