Please Attention, High Myopia!
Generally speaking, myopia could be classified into three categories according the different strengths. They are slight, medium, and high myopia. Below 3 diopters is supposed to the slight myopia, between 3 to 6 diopters is the medium one, and above 6 should be the high myopia. As for high myopia, it not only causes the unclear eye vision, but also may have the shape of the eyeballs changed. The retina and choroid may get extension, so that they will be deformed. If there is crack, it may result in the detachment of retina which means the lost of eyeglasses. The stronger the strength is, the greater the danger of that will be.
In order to prevent the detachment of the retina, you should avoid the strike to the eyes from the outside force. As a person having high myopia, you should try to reduce these fierce activities, such as running, jumping, especially diving.
