Visual fatigue may lead to itchy eyes. Visual fatigue is usually associated with overuse of the eyes, other eye diseases, environmental factors, mental and psychological factors, etc. Prolonged use of the eyes may lead to a decrease in the number of blinks, resulting in symptoms of eye discomfort, including dryness and itchiness. There may also be soreness and swelling of the eyes, leading to vision loss, blurred and double vision, and other conditions. In addition, if itchy eyes are present, they may be the result of an eye condition such as conjunctivitis or dry eye disease. In particular, when allergic inflammation occurs in the eyes, the patient will feel itchy eyes, which may be accompanied by dry eyes and other symptoms. When itchy eyes occur, it is recommended to consult a doctor for further examination, to clarify the cause with the help of the doctor, and to carry out targeted treatment.
