Additionally, blurry vision combined with a headache can sometimes indicate an underlying health issue or emergency condition.
Common causes of blurry vision and headaches are migraines, eyestrain, and other correctable vision issues.
This is especially true with migraines and cluster headaches.

Anauramay occur before the actual headache.
This makes diagnosing visual problems difficult.
Migraines can also cause tingling or numbness of the skin.
Treatment options for migraines include:
Cluster Headache
Cluster headachesare severe headaches that occur in clusters.
They typically cause pain around the eyes.
The pain often travels down the neck to include the shoulder.
The exact cause of cluster headaches is unknown.
A stroke can lead to many symptoms, including blurry vision and a painful headache.
Prompt care, ideally within an hour, is crucial to improve prognosis and help reduce disability.
Stroke treatment depends on the bang out of stroke and how quickly it is caught.
The most common cause of stroke is anischemicstroke (blood supply cut off, typically by a clot).
A medication called tissue plasminogen activator (tPA) is the first-line treatment for ischemic stroke.
Hypoglycemia is blood glucose below 70 mg/dL.
Individuals with blood sugar less than 70 mg/dL but greater than 55 mg/dL can typically follow the 15-15 rule.
Injectable glucagon kits are available for individuals at risk of significantly low blood sugar below 55 mg/dL.
However, individuals with severely low blood sugar may not be able to inject the glucagon themselves.
Seek emergency medical care after a glucagon injection.
GCA usually creates a headache that causes constant, throbbing pain in the temples.
Vision symptoms result from a loss of blood supply to the optic nerve and retina.
Other symptoms include:
Treatment may include:
Giant cell arteritis is considered a medical emergency.
If left untreated, the condition may cause vision loss in one or both eyes.
A delayed diagnosis is the most common cause of GCA-associated vision loss.
Specific treatments depend on whether treating the condition acutely during the initial presentation or treating the condition chronically.
It is often indicative of atherosclerotic disease, and patients may have co-existing cardiac conditions.
Sometimes, this condition is painless, and the most common reason patients seek care is decreased vision.
What Is a Retinal Migraine?
Complications of herpes zoster include:
Treatment for shingles involves antiviral medication to lessen the duration of symptoms.
The sooner medication is started after symptoms begin, the more effective it is.
Herpes zoster around the eyes is serious.
It requires immediate medical attention (including antiviral medication) to prevent damage to the ocular nerves and eyes.
Pseudotumor Cerebri
Pseudotumor cerebrioccurs when cerebrospinal fluid (CSF) accumulates in the skull.
Obesity, other health conditions, and some medications can contribute to the development of this condition.
Pseudotumor cerebri often causes headaches and changes in vision.
There may be a pulsating sensation in the head, and nausea and vomiting may also be present.
Left untreated, it can lead to vision loss because of pressure on the optic nerves.
Treatment aims to reduce fluid buildup and pressure.
While the condition is often treatable, it may reoccur.
Other common symptoms of carbon monoxide poisoning include:
You may feel like you have suddenly developed the flu.
Individuals who are sleeping or have had too much alcohol to drink may pass away before experiencing symptoms.
Set reminders on your phone to check the batteries and change the detector per the manufacturer’s instructions.
Additionally, avoid burning charcoal inside the home, using portable gas stoves indoors, and using generators indoors.
By correcting the vision problem, you’re able to often handle the headache.
Other symptoms include eye strain and difficulty seeing things up close.
Treatment involves corrective glasses or contact lenses.
Activities such as reading or threading a needle can become challenging because of blurry vision.
This condition is known aspresbyopia, affecting most individuals at some point.
Headaches develop as you attempt to compensate for the lack of focusing power.
Treatment includes drinking plenty of water to help hydrate your eyes and reduce eyestrain.
Summary
Migraines and cluster headaches are common causes of blurry vision with a headache.
They go away once you no longer have the headache.
Eye conditions or eye strain can also cause headaches.
