WHERE IT HURTS · BEHIND THE EYES
A headache behind the eyes is usually migraine, cluster headache, tension-type headache or pain referred from the upper neck. The urgent exceptions are acute angle-closure glaucoma, optic neuritis and giant cell arteritis.
Almost nobody who searches this has an eye problem. The eye is where the pain is felt, not where it is made. The exceptions are the reason this page has a red section.
Why does a headache hurt behind the eyes?
The orbit, the bony socket around the eye, is packed with nerve fibers. They come from the first branch of the trigeminal nerve. That same branch carries much of the pain in migraine and cluster headache. So a disorder with no eye disease at all makes pain the patient pins exactly on the eyeball. Eye doctor referrals for this are common, and the exam is usually normal.
THE COMMON CAUSES
- Migraine — often behind one eye, with nausea and light sensitivity. People want a dark room.
- Cluster — strictly one-sided and brutal, lasting 15 minutes to 3 hours. It comes with a red or watering eye, a drooping lid or a blocked nostril on the same side. People pace instead of lying down.
- Tension-type — a duller pressure behind both eyes, worse late in the day.
- Referred from the upper neck — starts at the back and ends behind the eye. That surprises people who assume pain travels front to back.
THE EYE REASONS THAT ARE URGENT
- Acute angle-closure glaucoma — a hard, red, painful eye with blurred vision and halos around lights. The pupil is stuck half-open. Nausea is common. This is a same-day emergency. Sight is on the clock.
- Optic neuritis — pain on moving the eye, with loss of vision or of how bright colors look. Needs assessment within days.
- Giant cell arteritis — new headache after 50 with a tender scalp, jaw ache on chewing or any visual change.
- Sudden, worst-ever onset, or new double vision or a drooping lid — emergency department, now.
That list is short, and none of it is subtle. If the eye itself is red, hard, or losing vision, this is not a headache page problem. The red-flag page.
What does it mean if the pain is always behind the same eye?
Is it always the same eye? Pain locked to one side that never swaps is a different talk from pain that switches. Cluster is fiercely one-sided and stays there. Migraine is usually one-sided, but it tends to switch sides between attacks over the years. Pain that has never once been on the other side deserves a proper look. Why the side matters.
Can screens cause a headache behind the eyes?
Long close-up focus does cause a real ache. But it is typically a pressure on both sides that eases within an hour of stopping. It does not come with nausea. Where screen time truly matters is upstream. It sets posture, it delays meals, and it pushes sleep later. Those three change how often a headache-prone brain tips over. The screen is rarely the cause. It is often part of the load. Screens and eye strain.
Frequently asked questions
I saw an optometrist and my eyes are fine. What now?
That is the expected result, and it is useful. It rules out the eye causes. What remains is a headache disorder sending pain to the eye socket. That is diagnosed by history and examination. What that visit covers.
Could it be sinus?
Less often than people think. True sinus pain comes with blockage, discolored discharge and usually fever. It does not come back in separate attacks with nausea. See the sinus-versus-migraine page.
It is one eye, unbearable, and I cannot keep still. What is that?
That picture is the cluster pattern. It is strictly one-sided and severe. You are restless, not still, with a watering eye or blocked nostril. It is worth naming fast, because it has specific treatment. Bring it up directly.
The detail is in the cluster headache page.
Should I get a scan?
Only if the examination or the history calls for it. What imaging settles and what it does not.
When should I worry about a headache behind the eyes?
Treat it as urgent if the eye itself is red, hard or losing vision, especially with halos around lights. That is acute angle-closure glaucoma, and it needs same-day emergency care. Pain on moving the eye with loss of vision or color needs assessment within days. A new headache after 50 with a tender scalp or jaw ache is urgent too. A sudden worst-ever onset, double vision or a drooping lid means the emergency department now.
What type of headache is behind the eyes?
Most often migraine, cluster headache, tension-type headache or pain referred from the upper neck. Migraine usually sits behind one eye with nausea and light sensitivity. Cluster is strictly one-sided and severe. It lasts 15 minutes to 3 hours and brings a red or watering eye. Tension-type is a duller pressure behind both eyes, worse late in the day. Neck pain starts at the back of the head and finishes behind the eye.
How is a headache behind the eyes diagnosed?
By history and examination. A normal eye check is the expected result, and it helps, because it rules out the eye itself. What remains is a headache disorder sending pain to the eye. A few details sort it out. Is it always the same eye? How long do attacks last? What comes with them, such as nausea or a watering eye? A scan is needed only when the history or examination calls for it.

The eye is where you feel it, not where it comes from
Once the eye itself is cleared, the question is which headache disorder refers there. That is a history and an examination, and it is the appointment.
