Myopia is hereditary, but whether myopia is hereditary or not depends mainly on the cause and the degree of myopia, and cannot be generalized. If myopia is caused by certain diseases and the patient starts to develop it in early childhood and the degree is very high, usually over 600 degrees, then this myopia is closely related to heredity and may be inherited to the next generation. However, most myopia is acquired and is caused by not protecting the eyes properly during adolescence. The lower the degree, the myopia is not related to heredity, mainly due to the lack of good eye habits and will not be inherited by the next generation. In any case, both parents should pay attention to protecting their eyes and slowing down the rate of progression in order to reduce the possibility of heredity. For children, it is important to develop the habit of eye protection from an early age and reduce other triggers.
