Dizziness and blurred eyes may be caused by physiological reasons, or cerebrovascular disease, vestibular dysfunction and other pathological reasons. 1. Physiological causes: overwork and lack of sleep can cause visual fatigue, which can cause dizziness and blurred eyes. 2. Pathological causes: cerebrovascular spasm or cerebral atherosclerosis triggers cerebrovascular stenosis, resulting in insufficient cerebral blood supply and dizziness caused by localized hypoxia in the brain. Compression of the optic nerve can be secondary to the symptoms of blurred eyes. Vestibular dysfunction, such as otolithiasis, can also be manifested as dizziness, blurred eyes, and balance disorders. If the symptoms of dizziness and blurred eyes occur frequently, it is recommended to go to the hospital to clarify the specific cause of the disease and standardize the treatment under the guidance of the doctor.
