Does Poor Eyesight Cause Headaches? | Get a Precise Answer

Have you ever noticed a headache that comes with blurry vision or visual changes and wondered: does poor eyesight actually cause headaches?  

Headaches can sometimes lead to blurred vision and other visual disturbances. This is especially true with migraine and cluster headaches.

Migraines can cause severe pain in and around the eyes, along with visual disturbances. An aura often appears before the actual headache and typically lasts about 20 minutes. This aura can include various visual symptoms.

Some people who experience migraine aura never develop the actual headache. This can make visual problems harder to diagnose. Migraines can also cause tingling or numbness of the skin. People with severe migraines may experience:

Certain medications, specific foods, strong smells, loud noises, and bright lights can all trigger migraine attacks.

Cluster Headaches

Cluster headaches are extremely painful headaches that occur in groups (clusters). They usually cause intense pain around one eye and this pain often radiates down the neck and can involve the shoulder. Other symptoms may include:

Cluster headaches can occur daily for several months at a time, followed by long headache‑free periods. The exact cause of cluster headaches is still unknown.

Vision Problems That Cause Headaches – Does Poor Eyesight Really Cause Head Pain?

On the other hand, eye and vision problems themselves can cause headaches when you overuse your eyes or struggle to maintain focus, as in eyestrain headaches. By correcting the underlying vision issue, you can often relieve the headache.

Eyestrain Headache

Overusing the focusing muscles in your eyes can lead to eyestrain and headaches. Common causes of eyestrain include prolonged screen use, such as:

Words and images on a digital screen are made of pixels and do not have sharply defined edges. Your eyes cannot lock focus easily on pixels, so they have to work harder, even if the display is high‑resolution. When the eye muscles become fatigued, you may develop a headache in or behind the eyes.

Hyperopia (Farsightedness)

Adults and children with uncorrected hyperopia (farsightedness) often develop frontal headaches, sometimes felt as “eyebrow pain.”  

If you are farsighted, you may have difficulty focusing on near objects. This constant effort to focus leads to eyestrain and headaches. Because you unconsciously compensate for your hyperopia by trying to focus more intensely, the headaches can become more frequent and more severe over time.

Presbyopia

Around the age of 40, most people begin to have difficulty focusing on near objects. Tasks like reading or threading a needle become harder because near vision is blurred.

This unavoidable, age‑related condition is called presbyopia and it affects everyone at some stage of life. Headaches can develop as you strain to compensate for the loss of near focus.

Reading glasses usually help relieve the underlying eyestrain. Jobs that require prolonged close‑up work, long‑term sun exposure, and existing hyperopia are among the most common risk factors for developing symptomatic presbyopia earlier or more severely.

Giant Cell Arteritis

Also known as temporal arteritis, giant cell arteritis (GCA) is an inflammation of the lining of the arteries that run along the temples. GCA typically causes a persistent, throbbing headache. Visual symptoms occur because blood flow to the optic nerve and retina is reduced. Other symptoms may include:

Pseudotumor Cerebri

Pseudotumor cerebri is a condition in which pressure inside the skull increases without an obvious cause. It is also known as idiopathic intracranial hypertension.

Pseudotumor cerebri commonly causes headaches and visual disturbances. If left untreated, it can lead to vision loss because the elevated pressure damages the optic nerves.

Fortunately, although about 65% to 85% of people with pseudotumor cerebri experience some degree of visual impairment, the problem is usually temporary and vision often returns to normal once the high pressure is brought under control.

So, does poor eyesight cause headaches? In many cases, yes. A headache can be a sign that there is a problem with your vision. For example, migraine and cluster headaches can cause temporary visual symptoms that disappear once the headache resolves.

However, other eye diseases can also cause headaches, and some can be serious, such as ocular ischemic syndrome (OIS), which develops when blood flow to the eye is reduced.  

For this reason, if you experience headaches and/or changes in vision, you should see your doctor to rule out serious medical conditions and properly address the question “Does poor eyesight cause headaches?” and treat the underlying issue.

What Should You Do If Your Vision Is Blurry and You Have a Headache?

If you have blurred vision and a headache at the same time, contact your healthcare provider. In some cases, this combination can be a sign of a more serious problem, such as herpes zoster (shingles) involving the eye or even a stroke.

How Long Does an Eyestrain Headache Last?

An eyestrain headache typically lasts up to about an hour after extended screen use, although in some cases it can last longer.
