Pain around the eye has dozens of possible causes, ranging from a simple stye to a sinus infection to a serious condition like glaucoma. The location, type, and timing of your pain are the best clues to what’s going on. A dull ache that worsens when you bend forward points to your sinuses, while a sharp, stabbing pain on one side suggests a nerve or headache disorder. Here’s how to sort through the most likely explanations.
Sinus Pressure and Infection
Your sinuses are air-filled cavities that sit directly behind your cheeks, forehead, and the bridge of your nose, surrounding the eye sockets on nearly every side. When they become inflamed or infected, the swelling creates pressure that you feel most around your eyes, especially between and just above them. The telltale sign is pain that gets worse when you bend over or lean forward, because that shifts fluid inside the swollen cavities.
Sinus-related eye pain usually comes with nasal congestion, thick mucus, and a feeling of fullness across the middle of your face. It often follows a cold. If the pain is mild and improving, it’s likely resolving on its own. If it lasts more than ten days, gets suddenly worse after seeming to improve, or comes with a fever, that points to a bacterial sinus infection that may need treatment.
Styes, Chalazions, and Eyelid Problems
If the pain is right at your eyelid rather than deep behind the eye, a stye is one of the most common culprits. A stye is essentially an infected oil gland or hair follicle at the base of your eyelashes. It looks like a small red pimple at the lid’s edge, feels very tender, and can make the entire eyelid swell. You might also notice crustiness, tearing, and a scratchy sensation as though something is stuck in your eye.
A chalazion looks similar but behaves differently. It forms farther back on the eyelid, grows more slowly, and usually isn’t painful at first. Over time it can become a firm, round bump. If it gets large enough to press against the eyeball, it can even blur your vision. Both styes and chalazions typically resolve on their own with warm compresses, though a chalazion can linger for weeks.
Cluster Headaches
Cluster headaches produce some of the most intense pain the human body can experience, and that pain centers squarely in, behind, or around one eye. A single attack lasts anywhere from 15 minutes to 3 hours, though most run 30 to 45 minutes. During a “cluster period,” which can stretch for weeks or months, the headaches strike daily, often several times a day, and frequently at the same time each night, usually one to two hours after you fall asleep.
The pain is sharp or stabbing, strictly one-sided, and often comes with visible signs on that same side: a red, watery eye, a stuffy or runny nostril, swelling around the eye, and a drooping eyelid. People in the middle of an attack tend to pace or rock rather than lie still, which is one way to tell a cluster headache apart from a migraine. Migraines also cause pain around the eye, but they build more slowly, last longer (hours to days), and typically make you want to lie down in a dark room.
Digital Eye Strain
If your pain is an aching, tired sensation that creeps in after hours of screen use, digital eye strain (sometimes called computer vision syndrome) is a likely explanation. Staring at a screen forces the tiny muscles that focus your lens to work harder and hold a fixed position for longer than they’re designed to. Over time, that sustained effort produces soreness in and around the eyes, along with headaches, blurred vision, and dry eyes.
The standard recommendation is the 20-20-20 rule: every 20 minutes, look at something about 20 feet away for at least 20 seconds. This gives your focusing muscles a chance to relax. Adjusting screen brightness, reducing glare, and making sure you’re blinking enough (people blink less when concentrating on screens) also help.
Periorbital and Orbital Cellulitis
An infection of the tissue around the eye is called periorbital (or preseptal) cellulitis. It causes redness, swelling, warmth, and tenderness of the eyelid and surrounding skin, but the eye itself moves normally and vision stays clear. It often starts after a minor skin break, an insect bite, or a nearby infection. Most cases respond well to oral antibiotics within about ten days.
Orbital cellulitis is a deeper, more dangerous version. The infection sits behind the protective tissue barrier that separates the eyelid from the eye socket itself. The most common route is spread from a sinus infection, particularly the ethmoid sinuses, which are separated from the orbit by an extremely thin wall of bone. In addition to swollen, red eyelids, orbital cellulitis causes pain when moving the eye, limited eye movement, bulging of the eye, and changes in vision. This is a medical emergency that requires hospital-level treatment and sometimes surgical drainage.
Acute Angle-Closure Glaucoma
This is one of the most urgent causes of eye pain. Acute angle-closure glaucoma happens when the drainage system inside the eye becomes suddenly blocked, causing pressure to spike rapidly. The result is severe eye pain, a red eye, blurred vision, halos around lights, headache, and nausea or vomiting. Permanent vision damage can happen quickly without treatment.
If you have sudden, severe eye pain combined with vision changes, nausea, or redness, treat it as an emergency. This is not a condition that improves on its own.
Optic Neuritis
Optic neuritis is inflammation of the nerve that carries visual information from your eye to your brain. The hallmark symptom is a dull ache behind the eye that gets noticeably worse when you move your eyes. Some people also see flashing or flickering lights with eye movements. Vision in the affected eye typically becomes blurry or dim, sometimes over the course of hours to days. Optic neuritis can be an early sign of multiple sclerosis, so it warrants a thorough workup even if the pain itself isn’t severe.
Trigeminal Neuralgia
The trigeminal nerve is the main sensory nerve of the face, and its uppermost branch covers the forehead, upper eyelid, and the area around the eye. When this nerve misfires, it sends sudden, electric shock-like jolts of pain that last anywhere from a fraction of a second to about two minutes. The pain is severe, one-sided, and can be triggered by everyday actions like washing your face, talking, chewing, brushing your teeth, or even feeling a cool breeze.
During an attack, you may also experience watering of the eye, excessive blinking, redness, and sensitivity to light on the affected side. Photophobia is especially common when the upper branch of the nerve is involved. The bursts of pain can repeat many times throughout the day, with pain-free intervals in between.
How Location and Timing Narrow It Down
Where exactly you feel the pain matters. Pain right at the eyelid margin points to a stye or blepharitis. Pain between the eyes and worse with bending suggests sinuses. Pain deep behind the eye that worsens with eye movement raises concern for optic neuritis. A sharp, stabbing pain around one eye with tearing and nasal congestion, especially at night, fits the pattern of cluster headaches. Sudden, severe eye pain with nausea and vision changes suggests acute glaucoma.
Timing is equally useful. Pain that builds gradually over a long screen session is almost certainly eye strain. Pain that comes in brief electric jolts triggered by touch is characteristic of nerve pain. Pain that arrives like clockwork at the same hour each night, lasts under an hour, and repeats for weeks follows the cluster headache pattern. And pain that appears alongside a swollen, warm, red eyelid after a bug bite or skin injury is consistent with a superficial infection.
Any eye pain that comes with vision changes, inability to move the eye normally, a bulging eye, or signs of illness like fever and vomiting needs prompt medical evaluation. In most other cases, the pain has a straightforward explanation, but getting the right diagnosis early makes treatment simpler and faster.
