Symptoms of visual fatigue are mainly manifested as eye symptoms, mental symptoms and so on. 1. Eye symptoms: visual fatigue can lead to eye fatigue, dry eyes, foreign body sensation, accompanied by severe eye congestion, soreness, pain, blurred vision, tearing, photophobia and other symptoms. Visual fatigue, if not relieved for a long time, leads to persistent spasm of the eye ciliary muscle, which is likely to lead to myopia, or cause the original myopia to deepen. 2. Mental symptoms: If visual fatigue is more serious, it may lead to dizziness, poor mental state, poor concentration and other mental symptoms. When the symptoms of visual fatigue appear, you should pay attention to the rational use of eyes, and if necessary, consult a doctor for treatment and adjustment under the guidance of the doctor.
