Is There A Connection Between Blurry Vision and Headache?

blurry vision and headache

Key takeaways:

  • Headaches and blurred vision are two common conditions that may happen simultaneously.
  • When a headache occurs with blurry vision, it may be considered a health issue or a symptom of another medical condition.
  • Several health conditions can cause both headaches and blurry vision at the same time.

 

What causes headaches and vision changes to happen at the same time? Many people have experienced both conditions simultaneously. But have you ever wondered if the two symptoms are connected, or do they occur simultaneously by pure coincidence?

Read on to discover the connection between blurry vision and headaches.

 

What Is a Headache?

 

Simply put, a headache is the sensation of pain or discomfort that you may feel in your head or face. Over 150 types of headaches are identified, and their intensity can vary greatly. Although generally, these types are often categorized into two groups: primary headaches and secondary headaches.

 

Primary Headaches

 

Primary headaches are instances in which the headache pain itself is the issue. This means the headache you feel is not a symptom of any other health issue. These are usually caused by overactive firing nerves in the brain, causing discomfort.

Natural and lifestyle-related factors, such as dehydration, hormone levels, and the consumption of certain foods and drinks, usually trigger primary headaches.

Some examples of primary headaches include:

  • Migraines
  • Tension Headaches
  • Cluster Headaches

 

Secondary Headaches

 

 

Secondary headaches are those connected to underlying health conditions a person may have. Headaches are considered a symptom instead of the main issue in such cases. Some common health conditions that can cause secondary headaches include sinus infections, head or neck injuries, dental problems, ocular problems, and jaw issues.

 

Possible Causes of Both Blurry Vision and Headaches

 

What causes blurry vision and headaches? Here are some of the common causes.

 

1. Migraine Headache

 

A common type of headache, migraines can last anywhere from a couple of hours to several days. In addition to pain, migraines may cause other symptoms, including nausea, vomiting, and light sensitivity.

There are different types of migraine headaches that a person may experience. Here are some of them:

  • Migraines with Auras: Migraine auras are sensory symptoms, like visual disturbances, that may happen before the onset of headache pain in this type of migraine. They commonly serve as a warning sign that the headache phase of your migraine will soon occur.
  • Common Migraines: This type of migraine comes unannounced. It doesn’t involve an aural phase, but it involves the telltale signs of a migraine headache.
  • Retinal Migraines: A retinal or ocular migraine may distress those who suffer from it because of its alarming visual symptoms. These include sudden vision loss in one eye or seeing bright, flashing lights. Luckily, this type of migraine is nothing to be worried about.

 

2. Cluster Headaches

 

This severe headache brings pain that lasts between 20 minutes and a couple of hours. However, it usually comes back several times over a few weeks. It usually affects only one side of the head. Additionally, people experiencing this headache may feel severe pain, pressure behind the eyes, and blurred vision.

 

3. Eye Strain

 

Eye Strain

 

Overfatigue of the eyes may cause both blurred vision and headaches.

Today, many people are glued to phones, TV monitors, and laptop screens. Images and texts on a screen are made up of pixels. Unfortunately, eyes can’t easily focus on these pixels, so they work overtime to let people see what’s on the screen. Because of this, extensive screen use makes one easily prone to eye strain.

But how does this cause both hazy vision and headaches?

If a person overuses their eye muscles, eye strain can develop, causing blurred vision. It may trigger a headache if people continue looking at screens with blurred vision.

 

Emergency Causes of Blurry Vision and Headaches 

 

What causes blurry vision suddenly? Some causes of sudden blurred vision and headaches require emergency medical attention. Here are some to look out for:

 

1. Stroke

 

Considered a serious medical emergency, a stroke happens when the blood supply to the brain is obstructed or reduced, possibly due to a blood clot or plaque. It may also happen when blood vessels in the brain suddenly burst.

When these instances happen, the transport of oxygen and nutrients to the brain is stopped, causing lasting damage or even cell death. As such, strokes may result in permanent brain damage, long-term disability, and death.

Some of the warning signs of a stroke include numbness or weakness of muscles in the limbs, the face, and other parts of the body, confusion, difficulty speaking, and difficulty balancing. Blurry vision, headaches, and dizziness are also common symptoms.

If you suspect that you’re suffering from a stroke, seeking immediate medical treatment is imperative. Prompt treatment is the key to minimizing the repercussions of this emergency medical condition.

 

2. Hypoglycemia or Low Blood Sugar

 

Hypoglycemia or Low Blood Sugar

 

A person’s blood sugar naturally changes throughout the day. This is most commonly observed between meals.

However, sometimes, a person’s blood glucose levels drop dangerously low. According to the CDC, blood sugar levels dropping to under 70 mg/dl is considered hypoglycemia, a serious medical condition that can be life-threatening. If not treated immediately, it may result in cardiac death and the development of other life-threatening conditions.

Hypoglycemia has many symptoms that easily pinpoint the condition. These include the following:

  • Headache and Double Vision
  • Anxiety
  • Sweating and Chills
  • Confusion
  • Increased Heart Rate
  • Pale Skin
  • Feeling of sleepiness
  • Feeling of weakness
  • Low energy
  • Feeling Hungry
  • Nausea
  • Feeling of numbness or pins and needles inside the mouth.

If you suspect that you are experiencing low blood sugar, consuming food or drinks with a lot of simple carbohydrates may be a good idea.

 

3. Traumatic Brain Injury

 

A traumatic brain injury may also cause headaches and sudden blurry vision. These instances involve hitting the head hard enough to cause possible damage to the brain.

However, the extent to which head injuries can affect a person significantly can vary. While mild head trauma (such as concussions) simply involves rest and close monitoring, more severe cases need immediate medical attention. Either way, seeking medical help to assess your case better is always a good idea.

 

Frequently Asked Questions

 

How do you get rid of blurry vision and headaches?

 

If you want to eliminate vision problems and headaches that occur simultaneously, you must first learn the source. In cases where you’re experiencing blurry vision with primary headaches, you can find out what your triggers are and avoid them.

If you’re experiencing these symptoms, many over-the-counter medicines may help relieve pain. For recurring migraines, your medical provider may prescribe medicine that you can take to minimize triggering this type of headache.

On the other hand, if vision loss and headaches are symptoms of medical conditions, the best way to eliminate them is to tackle the health issue itself.

 

Can you experience vision problems after migraines?

 

Yes. Unfortunately, the visual problems that you may experience with a migraine may linger for a bit even after the headache pain is gone. Luckily, these visual disturbances are usually harmless and temporary.

 

Can stress cause blurred vision and headaches?

 

Several studies have mentioned the links connecting headaches, blurred vision, and fatigue or stress.

Stress may affect the eyes in several different ways: it may dry out your eyes, and it increases a person’s risk of developing retinal disease and glaucoma.

On the other hand, stress is a known cause of tension headaches, the most common type of headache that involves dull, throbbing pain due to the muscles around the head experiencing strain.

 

Understanding the Connection

 

Experiencing blurry vision and headaches is common. Most of the time, they’re nothing to worry too much about. Hopefully, this article helped you discover and understand the connection between these two conditions. However, to be safe and sure about your health, understand your symptoms and when prompt medical attention is necessary.
