A myopia of 600 degrees is considered high myopia, and it can be inherited by the next generation. Moreover, eyes with high myopia are prone to other complications at the back of the eye, such as retinal breaks, macular holes, and posterior staphyloma. Therefore, it is crucial to pay attention to high myopia and have regular check-ups. If both parents have high myopia, there is an 80% chance that their children will tend to be myopic. If one parent has high myopia, there is a 50% chance that their children will tend to be myopic. Even if neither parent is myopic, there is still about a 20% chance that their children will be myopic.
