Why Do My Eyes Hurt When I Look Up?

Pain when you look up usually comes from strain or inflammation in the muscles, tendons, or nerves that move your eyes upward. Your eyes are rotated by six small muscles attached to the eyeball and anchored inside the bony eye socket, and any irritation along that chain can produce a sharp ache, a dull pull, or a grinding sensation when you direct your gaze overhead. The causes range from the utterly mundane (hours of staring at a poorly positioned screen) to conditions that need prompt medical attention (nerve inflammation or a fracture trapping one of those muscles). What follows covers the most likely explanations, roughly from common to uncommon, along with the red flags that should send you to a doctor.

Muscle Fatigue and Screen Ergonomics

The single most common reason your eyes hurt when you glance upward is that you have been asking the muscles around your eyes to hold an awkward position for too long. This happens constantly in modern life. If your computer monitor sits above your natural line of sight, your eyes have to angle upward continuously while you work. The muscles responsible for that upward gaze, particularly the superior rectus and inferior oblique, fatigue just like any other muscle held in a sustained contraction. Research on monitor placement has found that the angle at which you view a screen affects both visual and musculoskeletal strain, with eye-level and above-eye-level positions increasing discomfort compared to a slightly downward gaze.

The fix is straightforward. Position the top of your screen at or just below eye level so your default gaze angles slightly downward, roughly 15 to 20 degrees. That lets your eyes rest in their most relaxed position. If you work on a laptop, a separate keyboard and a stand that raises the screen can help. Frequent breaks matter too: the familiar 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) gives those muscles a brief rest that adds up over a workday.

Dry Eyes and the Role of the Tear Film

When your eyes are dry, every movement of the eyeball creates more friction against the inner surface of the eyelids. Looking up is especially uncomfortable because it exposes more of the corneal surface to air, accelerating tear evaporation, and because the upper eyelid has to slide over a wider arc of dry tissue. People with dry eye disease frequently report burning, stinging, and a gritty foreign-body sensation that worsens with eye movement. In clinical trials testing lubricating drops, patients with moderate dry eye experienced reductions of more than 70 percent in foreign-body sensation and pain after consistent use of topical lubrication, suggesting that restoring the tear film can meaningfully reduce movement-related discomfort.¹

If you notice that the pain when looking up is worse in air-conditioned rooms, on windy days, or after long stretches of reading without blinking, dry eye is a strong suspect. Over-the-counter preservative-free artificial tears are the standard first step. If those do not help after a few weeks, an eye doctor can check your tear production and recommend prescription options or punctal plugs that slow tear drainage.

Trochleitis and the Superior Oblique Tendon

One of the six eye muscles, the superior oblique, runs through a small cartilaginous loop called the trochlea, located in the upper inner corner of the eye socket near the bridge of the nose. When that loop or the tendon sliding through it becomes inflamed, the condition is called trochleitis, and it causes a very specific kind of pain: a deep, aching soreness in the upper inner part of the eye that gets sharply worse when you look up or toward the nose. The pain can mimic a headache or even be misdiagnosed as migraine. In one documented case, a young man with chronic headaches centered around one eye was finally found to have trochleitis after imaging revealed swelling of the superior oblique pulley and tendon.²

Trochleitis can be idiopathic (meaning no identifiable cause) or can show up alongside autoimmune conditions. It tends to affect one side at a time. The telltale clue is tenderness when you press on the upper-inner rim of the eye socket. Treatment usually involves anti-inflammatory medications, sometimes a local corticosteroid injection directly into the trochlear area, which often brings rapid relief. Because it mimics headache disorders so convincingly, trochleitis is probably underdiagnosed. If your pain is consistently localized to one spot near the inner brow and flares with upward gaze, it is worth mentioning to your doctor specifically.

Orbital Myositis

While trochleitis targets the tendon pulley, orbital myositis is inflammation of one or more of the extraocular muscles themselves. The condition typically comes on over days, producing pain with eye movement, swelling around the eye, redness of the eyelid, and sometimes double vision.³ If the inflamed muscle is the superior rectus or inferior oblique, looking up will be the movement that hurts most, because those are the muscles doing the heavy lifting for upward gaze.

Orbital myositis is uncommon but not rare, and it is one of the more treatable causes of eye movement pain. It usually responds well to oral corticosteroids, often within days. Imaging with CT or MRI typically shows a thickened, inflamed muscle. The condition can recur, and in people who have repeated bouts, doctors will often look for an underlying systemic inflammatory disease. If you develop noticeable swelling around one eye along with pain on looking up, that combination points toward myositis more than toward simple strain, and it warrants a prompt visit to an ophthalmologist.

Optic Neuritis and Nerve Inflammation

Optic neuritis, inflammation of the optic nerve, is one of the more serious causes of pain with eye movement. The classic presentation is a deep, aching pain behind one eye that worsens when you move the eye in any direction, including upward, often accompanied by a drop in vision or color perception. The pain tends to build over hours to days rather than appearing suddenly.

Why does moving the eye hurt when the problem is the nerve? The answer involves anatomy. The superior rectus and medial rectus muscles originate at the back of the eye socket, right where they share a tight space with the optic nerve. A study of over 100 eyes with optic neuritis found that pain was associated with inflammation in the posterior part of the optic nerve, supporting the idea that the muscle origins tug on the inflamed nerve sheath when the eye moves.⁴ Essentially, it is mechanical: the muscles pull, the swollen nerve gets yanked, and you feel it.

Optic neuritis can be an isolated event, but it is also one of the earliest presentations of multiple sclerosis. That does not mean everyone with eye-movement pain has MS, but it does mean that if you develop deep eye pain with any change in vision, blurred areas, dimming, or colors looking washed out, you should see an eye doctor urgently. An MRI can show the nerve inflammation, and treatment with high-dose corticosteroids can speed recovery.

Orbital Floor Fractures and Muscle Entrapment

If your pain when looking up started after a blow to the face, a ball to the eye, or any kind of facial trauma, the explanation may be structural. The floor of the eye socket is a thin plate of bone that can fracture from a direct impact. When it breaks, the soft tissue underneath the eye, sometimes including the inferior rectus muscle itself, can get trapped in the fracture line. Because the inferior rectus pulls the eye downward, trapping it means looking upward becomes physically restricted and painful. In one study of children with orbital floor fractures, the inferior rectus was directly entrapped in about 70 percent of cases with severe limitation of eye movement.⁵

This situation is considered a relative surgical emergency in children because their bones are more elastic and tend to snap back like a trapdoor, clamping down on the muscle. The longer the tissue stays trapped, the higher the risk of permanent damage to the muscle and lasting double vision.⁶ In adults, the fracture pattern is often more of a classic blowout with bone pushed outward, which can still trap tissue but may be less acutely compressive. Either way, if upward gaze is painful or restricted after facial trauma, especially if you also have double vision, numbness in the cheek, or swelling that is not improving, get to an emergency room. An orbital CT scan can reveal the fracture and show whether surgical repair is needed.

Brown Syndrome

Brown syndrome is a condition where the superior oblique tendon does not glide freely through the trochlea, limiting the eye’s ability to look up and inward. It can be congenital or acquired. In the congenital form, the cause has traditionally been attributed to anomalies in the trochlea or the tendon-muscle complex, though more recent work suggests some cases may involve developmental miswiring of the nerves that control the extraocular muscles, and the newest proposed explanation is the presence of a fibrotic strand along the superior oblique tendon.⁷

The acquired form can develop after eye surgery, after inflammation near the trochlea, or alongside autoimmune conditions. People with Brown syndrome notice that one eye cannot look fully upward and inward, and attempting to do so may produce pain or a clicking sensation. Mild congenital cases are often just monitored, especially in children, since some resolve on their own. More severe cases, particularly those causing noticeable misalignment of the eyes or head tilting to compensate, may be treated surgically. If you have always had trouble looking up with one eye specifically, Brown syndrome is worth discussing with a specialist.

Raised Intracranial Pressure

This is rare, but it is serious enough to mention. When pressure inside the skull rises, it can compress the optic nerves, producing a condition called papilledema, swelling of the optic disc at the back of the eye. Papilledema impairs the normal flow within the optic nerves and can compress them externally, and it may progress to significant vision loss if untreated.⁸ The associated headache often worsens with eye movement, coughing, or straining, and it tends to be worse in the morning.

Idiopathic intracranial hypertension, one of the more common causes of raised pressure in younger adults, occurs most frequently in women of childbearing age who are overweight. Symptoms include headaches, pulsatile tinnitus (a whooshing sound in the ears that follows your heartbeat), transient visual obscurations (brief episodes where vision goes grey), and pain with eye movement. If you are experiencing headaches that worsen when you look up combined with any visual changes, particularly brief blackouts of vision, seek medical attention quickly. A fundoscopic exam can detect papilledema, and treatment can prevent permanent vision loss.

Pain After Eye Surgery

If you have had eye surgery and developed pain when looking up afterward, the cause may be related to the procedure itself. Scleral buckling, a surgery for retinal detachment where a silicone band is placed around the eye to push the wall inward, can cause chronic eye pain. A study assessing chronic pain after scleral buckling found that the degree of scleral indentation was the only factor that reached statistical significance as a predictor of ongoing pain.⁹ The buckle sits under the extraocular muscles and can irritate them, producing discomfort with eye movements long after the initial healing period.

Other eye surgeries, including strabismus surgery (to correct misaligned eyes) and orbital decompression, can also leave scar tissue that restricts or irritates the muscles. Post-surgical pain with upward gaze is usually manageable with anti-inflammatory drops, but if it persists beyond what your surgeon expected, bring it up. In rare cases, the buckle or implant may need to be repositioned or removed.

Functional Eye Pain and the Stress Connection

Sometimes the eye exam is completely normal, the imaging is clean, and the pain persists. Functional eye pain is a recognized condition in which patients experience chronic eye discomfort, often described as burning, aching, or sharp sensations, without any visible structural abnormality. The pain is thought to involve neuropathic mechanisms, meaning the nervous system’s pain signaling has become disordered and is generating pain perception without a physical trigger at the eye itself.¹⁰

Stress, anxiety, and sleep deprivation can all amplify pain perception and muscle tension around the eyes. People who clench their jaw or tense their forehead habitually may develop referred pain that worsens with specific eye movements. This is not “imaginary” pain. Disordered pain signaling is a real neurological phenomenon, and functional eye pain can be just as disruptive as pain with a clear structural cause. Treatment often involves addressing the underlying stress, sometimes with cognitive behavioral approaches, and working with a pain specialist who understands neuropathic mechanisms. If you have been told your eyes look fine but they still hurt, the conversation does not have to end there.

When to See a Doctor

Most episodes of pain when looking up resolve with rest, better screen habits, or lubricating drops. But certain combinations of symptoms signal something that needs professional evaluation sooner rather than later:

• Vision changes: Any blurring, dimming, color distortion, or brief blackouts alongside eye-movement pain suggest optic nerve involvement and warrant urgent evaluation.
• Recent trauma: Pain with restricted upward gaze after a blow to the face could mean muscle entrapment in a fracture, which may need surgery within hours to days.
• Swelling and redness: Visible puffiness or redness around one eye with movement pain points toward orbital myositis or another inflammatory condition that responds to treatment but should not be ignored.
• Headache with eye pain: Especially if the headache is worse in the morning, worsens with coughing, or comes with a whooshing sound in your ears, raised intracranial pressure should be ruled out.
• Pain lasting weeks: Muscle fatigue resolves in days. Pain that lingers for weeks without improvement suggests something beyond simple strain and deserves investigation.

For the majority of people searching this question, the answer is reassuringly ordinary: tired eyes from too much close-up work, a dry ocular surface, or tension that builds through the day. Adjusting your workstation, using artificial tears, and giving your eyes regular breaks from screens addresses the problem more often than not. But the eyes are complex, and pain that persists, worsens, or arrives with other symptoms deserves a professional look, because the treatable conditions on this list respond much better when caught early.
