Understanding Headaches and Your Eyes

 

What Is a Headache?

A headache is pain or pressure that occurs anywhere in the head or neck. Depending on the type of headache, the symptoms can range from mild discomfort to severe, throbbing pain that interferes with daily activities. Headaches are one of the most common health complaints, and they can have many different causes — including issues related to the eyes and vision.

 

Types of Headaches

There are several kinds of headaches, and understanding the type can help find the right treatment.

 

1. Tension Headaches

• This is the most common type of headache.

• Patients describe this as feeling a tight band or pressure around the head, forehead, or behind the eyes.

• It is often caused by stress, fatigue, poor posture, or eye strain from near work or computer use.

• These headaches are usually temporary and are often relieved by an over-the-counter pain reliever. However, if taken on a regular basis, the pain medications can actually make the headaches worse.

 

2. Migraine Headaches

• Migraine headaches are common as well.

• Typically, this type of headache can cause throbbing pain on one or both sides of the head and may be accompanied by nausea, light sensitivity, sound sensitivity, or visual changes (called “aura”). The symptoms can last from a few hours to several days.

• Although the exact causes are usually not known, certain triggers can include stress, fatigue, certain foods, hormonal changes, lack of sleep, or visual strain.

• Women tend to suffer from migraines more than men. This can occur at any age, even in young children.

• Treating the symptoms and medications will help patients  with migraine headaches. There are no lenses available that can be worn to help with the light sensitivity experiences by many patients.

 

3. Cluster Headaches

• While less common than the previous two types of headaches, cluster headaches often occurring in “clusters” over several days, lasting for 1-2 months. This can happen several times a year. Each episode can last for 30-120 minutes.

• These patients have severe pain around or behind one eye. It may cause sweating, redness, tearing, or nasal congestion on the affected side.

• These headaches are more common in men and can be very intense, but brief in duration.

• Treatment usually includes medications.

 

4. Sinus Headaches

• This type of headache is more rare than once thought.

• It can cause pain or pressure around the eyes, forehead, or cheeks, with the pain worsening when bending forward or lying down.

• It is often associated with sinus infections, congestion, or allergies.

• Treatment includes clearing the offending agent with rinses, warm compresses, and OTC meds.

 

5. Eye Strain (Asthenopic) Headaches

• This headache results from uncorrected vision problems or overuse of the eyes.

• It is common in people who spend long hours reading, studying, or using digital devices.

• It is felt either in the eyes, behind the eyes, or around the brown of one or both eyes. There are accompanying symptoms of blurred vision, haloes around lights, and sensitivity to lights.

• Multiple visual treatments are available.

 

What Are the Symptoms of Headaches?

Headaches can feel different depending on the type and cause. Common symptoms include:

• Dull, aching pressure or tightness around the head or behind the eyes

• Sharp or throbbing pain on one or both sides of the head

• Sensitivity to light or sound

• Blurred vision or eye strain

• Nausea or dizziness

• Pain that worsens with reading, computer work, or focusing up close

 

Who Gets Headaches?

Almost everyone experiences headaches at some point. However, people who work long hours at computers, students, and those with untreated vision problems are especially at risk for eye-related headaches. Headaches are also more common in adults between the ages of 20 and 50, though they can occur at any age.

 

What Causes Headaches?

Headaches can be triggered by many factors, such as:

• Eye strain or uncorrected vision problems (nearsightedness, farsightedness, astigmatism, or presbyopia)

• Digital device use and prolonged screen time

• Stress or tension in the neck and shoulders

• Poor posture while reading or using computers

• Sinus pressure or allergies

• Dehydration or skipping meals

• Fatigue, certain foods, or alcohol

• Hormonal changes or lack of sleep

• Genetics

• Medical conditions such as high blood pressure, ear infections, tooth infections, or jaw (TMJ) disorders

 

How the Eyes Can Cause Headaches

Your eyes and brain work together to process visual information. If your eyes have to work harder than normal — for example, to focus at near distances, compensate for misalignment, or overcome an outdated prescription — this extra effort can lead to eye strain, fatigue, and headaches.
 

Common eye-related causes include:

• Uncorrected refractive errors (blurred vision at near or distance)

• Eye muscle imbalance (binocular vision disorders)

• Poor focusing ability (accommodation problems)

• Long hours of digital screen use

 

How Are Headaches Diagnosed?

Your optometrist will:

• Ask about your symptoms, lifestyle, and medical history

• Perform a comprehensive eye examination to check for vision changes, eye strain, or muscle imbalance

• Evaluate eye alignment and focusing ability

• Check for signs of eye disease. If necessary, you may be referred to your primary care physician or a specialist for further testing.

 

How Are Headaches Treated?

Treatment depends on the type of headache. If caused by the eyes, your optometrist will usually prescribe one or a few of the following options:

• Corrective lenses: Updating your glasses or contact lens prescription can relieve strain.

• Visual hygiene: Following the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) helps relax your focusing muscles.

• Ergonomic adjustments: Proper screen distance, lighting, and posture can reduce eye and neck tension.

• Hydration, rest, and stress reduction: Adequate sleep, fluids, and regular breaks help prevent tension headaches.

• Medication: Over-the-counter pain relievers or prescribed treatments may be recommended if headaches persist.

• Specialized lenses: Anti-fatigue and blue light–filtering lenses can reduce digital eye strain, while Avulux® lenses are good for those that are experiencing light sensitivity.

 

What Is the Prognosis?

Most headaches improve once the underlying cause is treated — especially when related to vision or eye strain. With proper care, lifestyle adjustments, and regular eye exams, many patients experience significant relief and fewer recurrences.

 

When Should You See an Optometrist?

Schedule an appointment if you:

• Have headaches that occur frequently or worsen with visual tasks

• Notice blurred vision, double vision, or light sensitivity

• Experience eye pain, redness, or pressure

• Haven’t had a comprehensive eye exam in over a year

• Have headaches that interfere with work, reading, or daily life

If headaches come on suddenly, are “the worst you have ever had”, or are accompanied by neurological symptoms such as vision loss, confusion, or weakness — seek immediate medical attention.

 

Tips to Prevent Eye-Related Headaches

• Get regular eye exams to ensure your prescription is current.

• Follow the 20-20-20 rule during screen work. Every 20 minutes, take a 20 second break, and look 20 feet away.

• Keep screens slightly below eye level and about an arm’s length away.

• Use proper lighting to reduce glare and shadows.

• Blink often and stay hydrated.

• Take regular breaks from close-up tasks like reading or computer work.

 

Your Vision and Comfort Matter

Many headaches have visual causes — and your optometrist can help identify and correct them. If you are struggling with frequent headaches, schedule an eye examination today to see how improving your vision could relieve your discomfort and improve your quality of life.
