The blurring of the eyes during dizziness may be caused by physiological reasons, eye diseases, cardiovascular and cerebrovascular diseases. 1. Physiological reasons: prolonged stress, overwork, high mental tension, etc., will easily lead to excessive energy consumption in the nerve center of the brain, resulting in transient cerebral blood supply insufficiency and the symptom of blurring of the eyes when dizziness occurs. 2. Eye diseases: when patients have conjunctivitis, severe astigmatism and other eye diseases, they may have blurred eyes when they are dizzy. 3. Cardiovascular and cerebrovascular diseases: If the patient suffers from cerebral arterial spasm, cerebral arteriosclerosis, anemia, hypertension and other cardiovascular and cerebrovascular diseases, there may be insufficient blood supply to the brain, which may cause blurring of the eyes during dizziness. After excluding the physiological causes of dizziness, patients should go to the hospital in time to improve the examination to clarify the specific causes of the disease, and actively treat under the guidance of the doctor.
