The doctor replied:

the Chinese name of RGP is high oxygen permeable hard contact lens. It is mainly suitable for patients with high myopia, high astigmatism and hyperopia. Its advantage is that the imaging quality is better, because it does not need to wear frame glasses, which can reduce the burden on the nose, which is more beautiful and convenient for movement. Its disadvantages: because it is in contact with the cornea, the nursing requirements are relatively high, which often induces conjunctivitis, keratitis, etc., so it is generally recommended to wear RGP for older children. If it is medium and low myopia, it is more likely to recommend wearing corneal plastic lens, because corneal plastic lens is a contact lens worn at night, so frame glasses can not be worn during the day, and it can also prevent the progress of myopia.
