A seventeen-year-old teenager who has been staying up late to read novels for a long time has serious short-sightedness. Two years ago, you often stayed up late to read novels, so your eyes needed to rely on transparent light to see things clearly. Nearsightedness is an eye disease that causes the eyes to see distant objects indistinctly. Long-term nearsightedness can lead to decreased vision and even eye diseases. In order to prevent and alleviate shortsightedness, it is recommended to maintain good living habits and avoid looking at objects at a close distance for a long time. At the same time, appropriate eye massage and hot compress should be carried out. At the same time, appropriate glasses or contact lenses should be worn to control the time of eye use and to check vision regularly. In addition, staying up late was not good for one's health and should be avoided as much as possible. Maintaining a good schedule and doing more outdoor activities is good for your health and prevent shortsightedness.
