The most common disease that occurs with sore eyes, tearing and accompanied by blurred vision would be eye strain, especially in teenagers. The causes of this condition are generally related to unreasonable eye habits, such as prolonged close eye use, prolonged reading or use of electronic products such as computers and cell phones, and frequent late nights, which can lead to eye fatigue symptoms and thus the above symptoms. In order to avoid this situation, or to alleviate the symptoms of the disease, you must pay attention to maintain the correct eye habits, try to reduce the time spent in close proximity to the eyes, and increase the time spent outdoors. If there is refractive error in the eyes, you need to wear glasses early to improve vision, which can effectively reduce the symptoms of eye fatigue, and you can also give local hot compresses to the eyelids to promote the symptoms to subside.
