A lot of people describe a deep, nagging ache “behind the eyes” or “behind one eye and into the temple.” It can feel like pressure, pulsing, or a tight band sitting in the socket. Sometimes it comes with dizziness, neck tension, or blurred vision.
That pain doesn’t always come from the eyeball itself. The area around your eyes is packed with nerves, muscles and blood vessels. Irritation in any of those structures, or stress on the visual system, can be felt as a headache behind or around the eyes.
Most of the time this is not an emergency.
Sometimes it is.
Below is how to tell the difference.
The most common reasons you get a headache behind the eyes
These are the causes we see and treat most often.
1. Eye strain and focusing fatigue
Screens, spreadsheets, late-night scrolling, driving at night, or poor lighting make the tiny focusing muscles in the eye work overtime. When those muscles fatigue, you can get an ache behind the eyes, across the brow, or into the temples. This is sometimes called asthenopia.
Typical signs:
- Worse after long computer or phone use
- Better after rest, better outdoors, better after sleep
- Dry, gritty, or “hot” eyes at the same time
Why it matters:
Uncorrected refractive error (short-sightedness, long-sightedness, astigmatism) forces your eyes to constantly “fight” to keep things clear. That constant effort can trigger recurrent headaches behind the eyes. Correcting the prescription, through glasses, contacts, or permanent correction like SMILE, LASIK, or ICL, often fixes the headache because it removes the strain.
This is one of the easiest wins in the clinic.
2. Dry eye and ocular surface irritation
If the front of the eye (the cornea) is slightly dry or inflamed, the nerves in that surface start firing. Your brain can interpret that as deep, aching eye pressure or a headache behind the eyes.
Typical signs:
- Burning, stinging, or sandy feeling
- Light sensitivity
- Blurry vision that clears when you blink
Modern life, with heating, air conditioning, contact lenses, and long screen sessions, is pushing dry eye earlier and harder in adults. Treating the surface, not just taking painkillers, usually brings real relief.
EuroEyes tip: We routinely scan the tear film and the oil glands in the eyelids during consultation. That tells us whether your “eye headache” is actually a dry eye problem.
3. Sinus pressure or sinus infection
Your sinuses sit around and behind the eyes. If they’re inflamed or blocked, they can create a dull, heavy, pushing pain behind both eyes, sometimes worse when you lean forward. You might also feel pressure around the nose, brow, and cheek.
Clues it’s sinus-related:
- You’re congested or recently had a cold
- You feel “full” in the face
- You’ve got facial tenderness around the nose or cheekbones
Sinus-related headaches are common and usually respond to decongestants, saline rinses, steam, hydration, and rest.
Important: if you have fever, worsening eye pain, or swelling around one eye, that needs urgent assessment. Severe sinus infections can spread into the space behind the eye and cause serious complications.
4. Migraine
Migraines can absolutely sit behind or around one eye, come with nausea, light sensitivity, visual aura (flashing zigzags or shimmering patches), and make you want a dark, quiet room.
Typical signs:
- Throbbing or pulsing pain behind one eye
- You feel sick or sensitive to light
- You’ve had similar attacks before
If that sounds like you, speak to a GP or headache specialist. Migraines are treatable, and you shouldn’t just live with them.
5. Cluster headache
Cluster headache is different. It’s brutally painful, usually on one side, centred in or behind one eye. People describe it as stabbing, drilling, or burning. The eye may water, go red, or the eyelid may droop on that side. You cannot sit still; it’s that intense.
This is an emergency. Get urgent medical help or NHS 111 right away, especially if this is new for you.
6. Neck and posture tension
If the muscles at the back of your neck and shoulders are tight, inflamed, or irritated by desk posture, long driving days, or grinding teeth, that tension can radiate forward and feel like pressure behind the eyes or across the temples.
Clue: pressing into the base of your skull or top of your neck recreates the pain.
Improving workstation ergonomics, gentle mobility work, heat, and regular breaks can make a big difference here.
7. Dehydration, fatigue, or poor sleep
Low hydration, missed meals, or running on very little sleep will lower your pain threshold and trigger tension-type headaches. People often feel these as a band across the brow or behind both eyes. Dehydration and alcohol can make them worse.
Hydrate, eat properly, and rest. It helps.
When the pain is only behind one eye
One-sided pain can be caused by:
- Migraine
- Cluster headache (severe, stabbing, often with red or watery eye)
- Sinus inflammation on that side
- Neck or nerve referral from one side of the neck
- Very high eye pressure
If the pain is sudden, severe, and comes with blurred vision, halos around lights, nausea, or vomiting, that can be a sign of acutely raised eye pressure (acute angle-closure glaucoma). That is sight-threatening and needs emergency treatment the same day.
Headache behind the eyes in the morning
Common reasons include:
- Overnight dry eye from heating or fans
- Grinding or clenching jaw at night
- Poor sleep or sleep apnoea
- Dehydration from alcohol or low fluid intake
Headache behind the eyes plus dizziness or neck ache
This combination often points to:
- Tension-type headache starting in the neck
- Migraine with vestibular symptoms
- Fatigue, screen strain, or dehydration
If dizziness is accompanied by sudden eye pain and visual changes, it needs urgent medical review to rule out neurological or pressure-related causes.
How to get rid of a headache behind the eyes
Short-term relief for non-emergency, strain-type causes:
- Take breaks from near focus: look 20 feet away for 20 seconds every 20 minutes
- Hydrate
- Apply a warm compress over the eyes and brow if you suspect sinus congestion
- Use lubricating eye drops if you’re dry or blinking helps
- Take over-the-counter pain relief if safe for you
If this is happening often, stop treating it like “just a headache” and book an assessment.
When a vision issue is the root cause
Many people with “mystery headaches” actually have:
- Uncorrected astigmatism
- A prescription that has changed
- Dry, unstable tear film
- Poor posture or viewing distance
- Early lens changes before cataract formation
In some cases, permanent vision correction such as SMILE, LASIK, or ICL removes the strain trigger completely. Many patients say the pressure headache disappears once the constant focusing effort is gone.
After eye surgery: what’s normal and what’s not
Normal: A mild ache, awareness, or “bruised” feeling in the first few days. Dryness or light sensitivity is common and usually temporary.
Not normal:
- Sharp pain that worsens instead of improving
- Headache behind one eye with nausea and halos
- Vision turning cloudy or dim
- Swelling, redness, or bulging around the eye
- Fever or feeling unwell
These symptoms need same-day review. Acute pressure spikes, infection, or inflammation are very treatable when caught early.
When to seek urgent help
- Severe pain behind one eye that comes on suddenly
- Eye pain with vomiting, rainbow halos, or rapid blur
- Drooping eyelid, red watery eye, and stabbing pain behind one eye
- New headache with double vision, fever, or swelling after sinus infection
- Over 50 with new temple pain, scalp tenderness, or jaw pain while chewing
When it’s routine but still worth checking
- You get the same headache behind the eyes most days
- You rely on painkillers for screen work
- You squint or lean in to see detail
- Your glasses are more than two years old
- You’ve noticed more dryness or glare since your 40s
Key message from Dr. Radhika Rampat
Most headaches behind the eyes are caused by things we can explain: strain, dryness, posture, sinus pressure, or migraine patterns. These are annoying but rarely dangerous.
However, sudden one-sided pain, vision changes, drooping eyelid, fever, or swelling are red-flag symptoms that need urgent care.
If you’re not sure which you have, come in for assessment. EuroEyes can rule out eye-surface issues, refractive strain, high eye pressure, or early lens changes. If your symptoms point to something neurological or sinus-related instead, we’ll tell you and guide you to the right care.
