Pain when you move your eyes is usually caused by strain, inflammation, or irritation affecting the muscles, nerves, or tissues surrounding the eyeball. The most common culprit is simple eye muscle fatigue from prolonged screen use, but the symptom also shows up in conditions ranging from sinus infections to optic nerve inflammation. What’s behind your pain depends largely on whether it came on gradually or suddenly, and whether other symptoms like vision changes or headache came with it.
Eye Muscle Fatigue From Screens
The most frequent and least serious cause is digital eye strain. Staring at a screen forces your eyes to continuously focus and refocus on pixelated characters, and the constant small movements needed to track text and images tire out the six tiny muscles controlling each eyeball. Over hours, this leads to a dull ache behind or around the eyes that flares when you look around, along with burning, heaviness, blurred vision, and headache. It tends to build through the day and improve after you rest your eyes.
This type of pain rarely signals anything dangerous. Taking regular breaks, adjusting screen brightness, and ensuring your prescription is current usually resolves it within a day or two. If you notice it keeps coming back despite these changes, an eye exam can check whether uncorrected vision problems are forcing your eye muscles to work harder than they should.
Sinus Infections
Your sinuses sit remarkably close to your eye sockets, and when they become infected and swollen, the pressure can make eye movement uncomfortable. The sphenoid sinus, located deep behind your nose near the base of the skull, is especially relevant. When inflamed, it can press on structures running through the area and cause retro-orbital pain, the deep ache felt behind the eye. About 70% of people with sphenoid sinus disease report headaches and this kind of behind-the-eye pain, and some develop double vision from the pressure on nearby nerves.
If your eye pain came alongside nasal congestion, facial pressure, or thick nasal discharge, a sinus issue is a strong possibility. The pain typically improves as the infection clears, whether on its own or with treatment.
Optic Neuritis
Optic neuritis is inflammation of the optic nerve, the cable that carries visual information from your eye to your brain. It causes a distinctive pattern: acute, dull pain behind the eye that clearly worsens when you move your eyes, along with fading color vision and dimmer brightness in the affected eye. Vision loss typically develops over less than a week.
The reason eye movement triggers pain in this condition is mechanical. At the back of the eye socket, the optic nerve runs right next to two of the muscles that move the eyeball. When those muscles contract to shift your gaze, they physically press against the inflamed nerve sheath, irritating it further. This makes the pain during eye movement feel sharp and specific in a way that’s hard to ignore.
The good news is that most people recover well. In a large clinical trial that followed patients for five years after an optic neuritis episode, 87% regained visual acuity of 20/25 or better in the affected eye. Only 3% had vision of 20/200 or worse at the five-year mark. Optic neuritis can be an early sign of multiple sclerosis in some people, so it does warrant medical evaluation even if the eye pain itself resolves.
Scleritis
The sclera is the tough white outer wall of your eyeball, and when it becomes inflamed, the result is a piercing, boring pain that gets worse with eye movement. Scleritis pain is often described as deep and severe, sometimes waking people from sleep. It differs from the milder, more superficial redness of episcleritis, which affects only the outermost layer of the sclera and tends to cause irritation rather than true pain.
Scleritis is less common than many other causes on this list, but it’s worth knowing about because it sometimes reflects an underlying autoimmune condition. The affected eye is usually visibly red, and the pain doesn’t respond well to over-the-counter drops.
Orbital Myositis
This is direct inflammation of one or more of the muscles that move the eye. It’s rare, but when it strikes, the connection between eye movement and pain is immediate and obvious. About 95% of patients experience retro-orbital or orbital pain, and 90% report that the pain gets significantly worse with eye movement. Double vision occurs in roughly 85% of cases because the inflamed muscles can’t contract and stretch normally.
Orbital myositis typically develops over a few days. In its milder form, which accounts for about 75% of cases, symptoms are limited to pain, double vision, and some redness on the white of the eye near the affected muscle. A more severe form adds swelling of the eyelid, bulging of the eye, and puffiness of the tissue lining the eye. It responds well to anti-inflammatory treatment and most people recover fully.
Corneal Problems
Damage to the cornea, the clear front surface of the eye, can make any eye movement painful because the inner surface of your eyelid slides across the injured area each time you shift your gaze. Corneal scratches (abrasions) or recurrent corneal erosions cause sharp, stinging pain that flares with both eye movement and blinking. You might also notice tearing, light sensitivity, and a gritty or foreign-body sensation.
These injuries often have an obvious trigger: something got in your eye, you rubbed it too hard, or you slept in contact lenses. Recurrent erosions can happen repeatedly, typically upon waking, because the healing corneal surface sticks to the eyelid during sleep and tears open again.
Headache Disorders
Migraines and cluster headaches can both make the area around the eye intensely painful, and that pain often feels worse when you look around. Migraines produce a throbbing, pulsing headache on one side of the head that worsens with physical activity, light, sounds, or smells. The eye on the affected side may feel sore when moved.
Cluster headaches are rarer, affecting roughly 1 in 1,000 people, but they produce some of the most severe pain known in medicine. The pain concentrates behind or near one eye and comes with watering, redness, a droopy eyelid, and a runny or stuffy nostril on the same side. Cluster headaches arrive in bouts lasting weeks to months, often at the same time of day.
When Eye Movement Pain Needs Urgent Attention
Most causes of pain when looking around are either benign or treatable without urgency, but a few combinations of symptoms signal something that needs same-day evaluation:
- Pain with vision loss developing over days. This pattern points to optic neuritis or another inflammatory process affecting the optic nerve. Decreased color vision and dimmer brightness in one eye are key clues.
- Severe eye pain with a red eye, nausea, and halos around lights. This can indicate acute angle-closure glaucoma, a condition where pressure inside the eye spikes dangerously. The pupil may appear dilated and fixed. This is a true emergency.
- New headache with vision loss in someone over 60. Giant cell arteritis, an inflammation of blood vessels near the temples, can threaten vision permanently if not treated quickly.
- Sudden flashes, floaters, and a shadow or curtain across your vision. This combination suggests a possible retinal detachment, which is painless but requires urgent surgical evaluation.
Pain with eye movement that comes on gradually, improves with rest, and isn’t accompanied by vision changes or severe redness is far more likely to be muscle fatigue or mild strain. But if it persists for more than a few days or keeps coming back, getting it checked helps rule out the less common causes that benefit from early treatment.
