Hereditary myopia can hardly be cured because hereditary myopia is mainly due to the presence of genes among the genes that trigger the development of myopia, or genetic mutations that have already occurred later in life, and current gene therapy is not up to the level of modifying the genes. So once there is a genetic factor present, it is also equivalent to having an intrinsic drive for myopia development, which will drive the eye to keep elongating. If there is a family genetic predisposition, it is important to try to prevent the development of myopia or to take preventive and control measures against myopia. Eugenics can be adopted, and eugenics mainly emphasizes not marrying close relatives within the family. In addition, if you have a family history of high myopia, you should not marry someone with high myopia when choosing a spouse to avoid the impact on the next generation. If a child from a family with high myopia shows hereditary myopia from a young age, it is also possible to establish a refractive developmental profile early, do preventive and control measures early, and do more outdoor activities to slow down the development of myopia.
