What is the degree of myopia 4.4

Normal adults whose vision reaches 5.0 belong to normal, and those whose vision is lower than 5.0 belong to vision decline, but the causes of vision decline include astigmatism, cataract, fundus diseases, etc., which need to be diagnosed by optometry examination in time. Everyone's eye adjustment ability is different. The naked eye vision is the same, and the degree of myopia is also different. There is no proportional relationship between the two. After optometry examination, it can be clear whether there is myopia or astigmatism, and at the same time, it is necessary to wear glasses of appropriate degree according to the results of optometry. After myopia is formed, it is not treatable. It is recommended to develop good eye habits and control the degree to continue to grow. If the elderly show decreased vision, it is not excluded that it is caused by diseases such as cataract. It is also necessary to go to the hospital in time for slit lamp examination to clarify the cause.
