What causes blurred vision and dizziness?

Possible causes of blurred vision and dizziness may include the following: 1. Eye-related issues: With aging, the lens hardens and the ciliary muscle's contractile ability declines—this is a physiological phenomenon. Refractive errors (such as myopia or hyperopia) or eye diseases (such as keratitis, glaucoma, etc.) may also cause blurred vision. 2. Insufficient cerebral blood supply: Cervical spondylosis may compress the vertebral artery, leading to inadequate blood flow to the brain and causing dizziness and blurred vision. Hypertension, hypotension, and anemia may also impair cerebral circulation, resulting in these symptoms. 3. Other medical conditions: Brain disorders such as cerebral atherosclerosis or brain tumors may affect vision and cause dizziness. Additionally, hypoglycemia, heart disease, and other systemic conditions may also lead to symptoms of blurred vision and dizziness.
