A headache behind your eyes is most often a migraine, tension headache, or cluster headache. Less commonly, it can signal a sinus infection, eye strain from screens, or a more serious eye condition. The location alone doesn’t pinpoint the cause, but the pattern of pain, how long it lasts, and what else you feel alongside it can help you narrow it down.
Migraine
Migraine is the most common cause of recurring pain behind one or both eyes, and it’s far more common than most people realize. In one large study, 88% of people who believed they had “sinus headaches” actually met the clinical criteria for migraine. That misdiagnosis happens because migraines can cause facial pressure, nasal congestion, and watery eyes, symptoms people naturally blame on their sinuses.
What sets migraine apart is the combination of throbbing or pulsing pain with sensitivity to light (reported by up to 80% of migraine sufferers), sensitivity to sound, and nausea. The pain typically affects one side of the head and can settle deep behind one eye. Episodes last anywhere from 4 to 72 hours. Some people see visual disturbances beforehand, like shimmering lines or blind spots, known as aura. Others get no warning at all.
If your behind-the-eye pain comes with light sensitivity, nausea, or a pulsing quality, and it tends to recur, migraine is the most likely explanation, even if you’ve always assumed it was your sinuses.
Tension Headache
Tension headaches are the most common headache type overall, and they often create a sensation of pressure behind the eyes. The classic feeling is a tight band squeezing across your forehead or wrapping around the sides and back of your head. That tightness can radiate forward and settle behind the eyes as a dull, steady ache.
Unlike migraines, tension headaches don’t usually cause nausea or light sensitivity. The pain is mild to moderate rather than severe, and it affects both sides of the head. It often builds gradually over the course of a day, especially during periods of stress, poor sleep, or long hours at a desk. Muscle tenderness in the scalp, neck, and shoulders is common alongside the head pain.
Cluster Headache
Cluster headaches are rarer but unmistakable. The pain is severe and boring, centered directly behind or around one eye. A single attack lasts 15 minutes to 3 hours, though most run 30 to 45 minutes. What makes them distinctive is the pattern: they strike daily, often several times a day, frequently at the same time each night, typically 1 to 2 hours after you fall asleep.
The affected side of the face reacts dramatically. You’ll notice redness and tearing in that eye, a stuffy or runny nostril on the same side, facial sweating, swelling around the eye, or a drooping eyelid. People with cluster headaches often can’t sit still during an attack. They pace, rock, or press against their eye. This restlessness is a key difference from migraine, where most people prefer to lie down in a dark room.
Cluster headaches arrive in “clusters” lasting weeks or months, then disappear completely for months or even years before returning.
Sinus Infection
True sinus headaches do cause pain behind and around the eyes, but they’re much less common than people think. A real sinus headache comes from acute sinusitis, where inflammation and mucus buildup block the sinus cavities near your eyes. The pain gets worse when you bend forward, and it comes with thick nasal discharge, reduced sense of smell, and often fever.
Most acute sinusitis is caused by a viral infection (a common cold) and clears up within a week to 10 days. Bacterial infections can follow, causing symptoms that linger or worsen. The key distinction: if you have facial pressure and pain behind your eyes but no thick discolored discharge, no fever, and no recent cold, you’re probably dealing with a migraine rather than a sinus problem.
Digital Eye Strain
Hours of screen time can produce a dull ache behind the eyes that feels like a headache. This is digital eye strain, sometimes called computer vision syndrome. Along with the headache, you may notice burning or irritated eyes, dry eyes, blurred vision, and difficulty refocusing when you look away from the screen. Neck and shoulder pain often tag along.
The cause is sustained close-focus work. Your eye muscles fatigue from holding the same focal distance for too long, and your blink rate drops, drying out the surface of your eyes. The standard prevention strategy is the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This headache resolves once you step away from screens and rest your eyes, which helps distinguish it from other causes.
Acute Angle-Closure Glaucoma
This is the one cause on this list that requires emergency care. Acute angle-closure glaucoma happens when fluid pressure inside the eye spikes suddenly, sometimes reaching three to four times the normal level. It causes intense pain in and behind one eye, along with blurred vision, rainbow-colored halos around lights, eye redness, nausea, and vomiting.
The pain comes on rapidly and is severe. If you experience sudden, intense eye pain with vision changes and halos, that’s not a typical headache. It needs immediate treatment to prevent permanent vision loss.
How to Tell the Difference
The most useful clues are timing, severity, and accompanying symptoms:
- Throbbing pain with light sensitivity and nausea points to migraine, especially if episodes last hours and recur over months or years.
- Steady pressure across the forehead that radiates behind the eyes, without nausea, suggests a tension headache.
- Excruciating pain behind one eye with tearing and nasal congestion on the same side, lasting under an hour and returning at predictable times, fits a cluster headache.
- Facial pressure with thick nasal discharge and fever after a cold suggests a genuine sinus infection.
- Dull ache that builds during screen time and resolves with rest is likely digital eye strain.
- Sudden severe eye pain with vision changes and halos signals a possible eye emergency.
Warning Signs That Need Urgent Attention
Most headaches behind the eyes are benign, but certain patterns suggest something more serious. A headache that reaches maximum intensity within seconds (sometimes called a thunderclap headache) needs immediate evaluation. The same applies to a headache accompanied by fever and stiff neck, a new headache developing after age 65, headaches that are progressively worsening over weeks, pain triggered by coughing or straining, or any headache paired with neurological changes like weakness, confusion, or vision loss.
A headache that changes character from your usual pattern also warrants attention. If you’ve had migraines for years but this one feels fundamentally different, that shift itself is a red flag worth investigating.
