Pain in or around your eyeballs usually comes from something treatable, like dry eyes, eye strain, or a sinus infection. Less commonly, it signals a condition that needs prompt attention. The type of pain you feel, where exactly you feel it, and what else is going on with your vision all point toward different causes.
Eye Strain From Screens
The most common reason your eyes hurt at the end of a day is digital eye strain. Staring at a screen for hours reduces your blink rate, which dries out the surface of your eyes and forces the tiny muscles that control focus to work overtime. The result is an aching, tired feeling in and around both eyeballs, sometimes with a headache across the forehead.
The standard recommendation is the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. Beyond that, check your lighting. Bright overhead lights or sunlight behind your screen create glare that forces your eyes to strain harder. Adjusting your chair height so you look slightly downward at your monitor also helps, because your eyelids cover more of the eye’s surface in that position, reducing dryness. Over-the-counter artificial tears can prevent the dry, gritty feeling even before symptoms start.
Dry Eye Disease
If your eyes burn, sting, or feel like something is stuck in them, dry eye disease is a likely cause. Your cornea has the highest density of pain-sensing nerve endings of any tissue in the body, which is why even mild dryness can feel disproportionately painful. Wind and bright light tend to make it worse.
In straightforward cases, the tear film is either too thin or evaporates too quickly, and artificial tears bring relief. But in some people, the nerve endings in the cornea become sensitized over time, resetting their pain threshold too low. When that happens, the pain alarm fires even when the tear film looks normal. Inflammation from repeated nerve activation ramps up the pain signaling further. This is why some people with dry eye pain don’t improve with standard drops. If your eye pain persists despite consistent use of lubricating drops, the issue may have shifted from a surface problem to a nerve-level one, and an eye doctor can help sort that out.
Sinus Pressure and Referred Pain
A deep ache behind one or both eyes, especially during a cold or allergy flare, often comes from inflamed sinuses rather than the eyes themselves. The orbit (the bony socket holding your eyeball) is separated from the ethmoid and frontal sinuses by only paper-thin sheets of bone. These structures also share blood vessels, so prolonged sinus inflammation can spill over and irritate the tissues around the eye.
This type of pain tends to feel like a dull, pressing ache that gets worse when you bend forward. It can sharpen if the inflammation reaches the lining around the eye socket, which is packed with nerve fibers. If you also have nasal congestion, thick mucus, or facial tenderness, your sinuses are the most likely culprit. Treating the sinus inflammation with decongestants, saline rinses, or allergy management usually resolves the eye pain too.
Contact Lens Problems
Contact lenses sit directly on the cornea, and wearing them too long, sleeping in them, or using damaged lenses can scratch or irritate that sensitive surface. Symptoms range from a mild foreign-body sensation and itchiness to sharp pain, light sensitivity, and noticeably blurred vision. A corneal abrasion (a small scratch) typically causes a sudden, stinging pain that gets worse with blinking.
The universal first step is to remove the lenses. If redness or pain continues after taking them out, you need an eye exam promptly. Corneal infections from contact lens use can progress quickly and threaten your vision, so persistent symptoms after lens removal aren’t something to ride out at home.
Headaches and Migraines
Tension headaches and migraines frequently produce pain that feels like it’s coming from the eyeballs themselves. A tension headache typically creates a band-like pressure across the forehead and behind both eyes. Migraines tend to pound on one side and may bring light sensitivity, nausea, or visual disturbances like shimmering lines before the headache peaks. Cluster headaches cause severe, stabbing pain around or behind one eye, often with tearing and redness on that side.
If your eye pain consistently arrives alongside headaches, treating the headache pattern is usually the path to relief. Isolated eye pain without headache points toward an eye-specific cause instead.
Uveitis
Uveitis is inflammation inside the eye itself, most commonly in the front portion involving the iris. It causes a deep, aching pain that tends to worsen in bright light. Your eye will usually look red, your vision may blur, and you might notice increased sensitivity to light. It can affect one or both eyes and sometimes develops alongside autoimmune conditions.
Unlike surface irritation from dryness or strain, uveitis pain doesn’t improve with rest or drops from the drugstore. It requires prescription treatment to control the inflammation and prevent damage to structures inside the eye.
Optic Neuritis
If your eye pain gets noticeably worse when you move your eyes side to side or up and down, optic neuritis is one possibility. This is inflammation of the optic nerve, the cable that carries visual information from your eye to your brain. Over 90% of people with optic neuritis experience pain, and it characteristically worsens with eye movement because the swollen nerve shifts inside its sheath.
Along with movement-related pain, you may notice dimming or blurring of vision in one eye, faded colors, or a blind spot. Optic neuritis sometimes occurs as a first sign of multiple sclerosis, though it can also result from infections or other inflammatory conditions. It warrants evaluation within a day or two.
Acute Angle-Closure Glaucoma
This is the cause you don’t want to miss. Acute angle-closure glaucoma happens when fluid drainage inside the eye suddenly blocks, causing pressure to spike rapidly. Normal eye pressure falls between 10 and 20 mmHg. During an acute attack, it can climb far beyond that range within hours.
The pain is severe, often accompanied by nausea or vomiting, a visibly red eye, blurred vision, and halos or rainbow-colored rings around lights. It tends to come on suddenly, and many people describe it as the worst eye pain they’ve ever felt. This is a true emergency. Without treatment within hours, permanently elevated pressure can damage the optic nerve and cause irreversible vision loss.
When Eye Pain Needs Urgent Attention
Most eyeball pain resolves with rest, lubricating drops, or treating an underlying issue like sinus congestion. But certain combinations of symptoms call for same-day or emergency care:
- Sudden, severe pain with nausea, vomiting, or halos around lights (suggests acute glaucoma)
- Pain with vision loss or noticeable dimming in one eye
- Pain that worsens with eye movement alongside blurred or faded vision
- Eye pain after an injury, including chemical splashes or something striking the eye
- Deep pain with a red eye and light sensitivity that doesn’t improve overnight
Mild, symmetrical achiness that improves with breaks from screens or feels better in the morning is rarely dangerous. Pain that is one-sided, intensifying, or paired with vision changes tells a different story and benefits from professional evaluation sooner rather than later.
