According to the lecture on eye health, high myopia is not suitable for strenuous activities, one of the reasons is that it is afraid of causing retinal detachment and blindness. I wonder what your actual situation is. And what is the purpose of running: is it a course prescribed by the university or for self-exercise.

From the point of view of fitness and exercise, I suggest starting with walking exercise; On the one hand, this way will naturally not produce too intense movements, on the other hand, it will gradually adapt itself to "exercise"; A good form to lay the foundation for one's physique; After several months or even longer accumulation, you can do further exercise according to the specific situation at that time, such as fitness running at an appropriate speed.

Although high myopia, but this should not be an excuse, it is very beneficial to participate in sports activities suitable for your physical condition.
