It is usually considered that myopia becomes stable after the age of 18 years and does not continue to progress. However, different cases should be treated differently. This is generally true for physiological myopia, but in the case of pathological myopia it is no longer limited to this age, because pathological myopia is usually due to congenital genetic factors, so myopia can develop regardless of the age. Therefore, many genetic causes of myopia are generally high, and may exceed 1000 or 2000 degrees, and I have even seen 3000 degrees of myopia in clinical practice. In order to avoid the rapid growth of myopia, no matter what age you are, you should pay attention to reasonable eye habits. The use of computers, cell phones, television and other electronic products should also be controlled, and the time spent outdoors should be increased to slow down the development of myopia.
