Blurry vision and dizziness are two very common complaints. Dizziness refers to unpleasant sensations that interfere with steadiness and balance, which can result from standing up too quickly, diet problems or infections. Blurry vision refers to a lack of vision details and visual disturbances. The most common causes of blurry vision include age, headaches and vision problems. Consult your physician when blurry vision and dizziness occur together, as this can be an indication of mild to severe health problems, including everything from stress to brain tumors.
Migraine
Migraines are a persistent headache that may occur several times a week. They typically affect one side of the head and cause chronic pain. Migraines may occur with warning signs called auras, which include visual disturbance and increased sensitivity to light. MedlinePlus reports that a migraine occurs three times more often in woman than in men. Approximately 11 out of every 100 people experience the condition.
The symptoms of migraines include sensitivity to light and sound, blurred vision, throbbing pain, fatigue and dizziness. The cause of the condition is unknown, but experts believe it results from abnormal brain activity and triggering factors, explains MedlinePlus. Possible triggers for migraines include loud noises, diet, odors, allergic reactions, bright lights and changes in sleep patterns.
Blood Pressure
Blood pressure is the force or push of blood against the walls of the arteries. It results from the force of the arteries as they resist blood flow and the heart as it pumps blood through the circulatory system and arteries. When blood pressure is either too low or too high, it can cause blurry vision and dizziness.
A common form of low blood pressure that causes blurry vision and dizziness is orthostatic hypotension. This form of low blood pressure occurs when standing up too quickly, causing blood vessels to keep from constricting properly. The condition causes symptoms of confusion, blurred vision, nausea, headache and weakness that last for a few minutes, according to the Mayo Clinic.
Meniere's Disease
Meniere's disease is a condition of the inner ear and usually only affects one ear. The symptoms of the inner ear disorder occur with changes in fluid within the ear and include blurred vision, pain, tinnitus, hearing loss, discomfort, fatigue and intense dizziness. Symptoms of Meniere's disease are episodic, meaning symptoms occur in episodes and may result at any time.
The National Institute on Deafness and Other Communication Disorders approximates that there are 615,000 individuals in the United States diagnosed with the disease and 45,000 new cases each year. The cause of Meniere's disease is unknown, but experts believe changes in fluids within the inner ear, acoustic trauma and viruses that cause disturbance within the inner ear are likely factors.
