Rubbing your eyes certainly does not cause myopia, and there is absolutely no need to worry about that. There are two common causes of myopia. The first one is hereditary factors. If both parents have high myopia, the possibility of developing high myopia in the future is much greater than normal. The second is acquired bad eye habits, which is the most common cause of myopia in adolescents. After getting myopia, the vision will be blurred, and the larger the myopia is, the less clear it is, so it is necessary to improve the vision through various corrective methods as early as possible to avoid eye fatigue, and also to slow down the development of myopia. At present, there are three main methods of correction, the first one is frame glasses; the second one is corneal contact lenses; and the third one is surgical treatment, which is only available after the age of 18.
