Eye Pain

A gritty ache, a sharp stab, or a deep throb behind the eye can all mean very different things. Some settle on their own within a day. Others need same-day treatment. A proper assessment is the only reliable way to know which.

What Is Eye Pain?

Eye pain covers a wide range of sensations: gritty discomfort, a burning ache, a sharp stab when you blink, or a dull throb felt behind the eye itself. Where it comes from, and how urgently it needs attention, depends entirely on which of these you’re describing.

Pain on the surface of the eye, often gritty or burning, usually comes from something affecting the cornea or the tear film: dryness, a foreign body, or a small scratch. Pain around the eyelid tends to come from a blocked gland or a localised infection. Pain felt deeper, behind or around the eye itself, points toward causes inside the eye or, occasionally, somewhere else in the head entirely.

Most eye pain is minor and settles within a day or two. A smaller number of causes need same-day treatment, and the two can feel surprisingly similar at first. That distinction is what an assessment is for.

Symptoms to Look Out For

Could it be something else?

Gritty, burning pain that’s been building for weeks is more often dry eye than an emergency; see our dry eye page for that pattern specifically. A tender lump on the eyelid itself usually points to a stye or chalazion rather than pain from within the eye. Our red eye page covers pain alongside significant redness in more depth. A proper assessment is the only reliable way to tell these apart.

Sudden, severe eye pain, especially with blurred vision, nausea, or seeing halos around lights, can mean a rise in eye pressure that needs same-day treatment.

The same applies to pain following a chemical splash, a penetrating injury, or pain so severe you can’t keep the eye open. Don’t wait for a routine appointment.

What Causes Eye Pain?

This kind of pain has several distinct categories of cause, and the right treatment depends entirely on which one applies.

Surface Irritation

Dryness, a foreign body, or a corneal abrasion all irritate the surface of the eye and cause gritty or sharp pain, often worse with blinking. This is the most common category and usually the least serious.

Eyelid and Gland Problems

A blocked meibomian gland, stye, or chalazion causes localised, tender pain focused on one spot of the eyelid, often with visible swelling.

Inflammation Inside the Eye

Conditions such as uveitis or scleritis cause a deeper ache, often with light sensitivity and redness, and need prompt treatment to prevent complications.

Raised Eye Pressure

A sudden rise in eye pressure, as in acute angle-closure glaucoma, causes severe pain with blurred vision and is a genuine same-day emergency.

Not All Eye Pain Needs the Same Urgency

A gritty ache that’s been nagging for a fortnight and a sudden stabbing pain that started an hour ago are both “eye pain,” but they call for completely different responses. One is worth mentioning at a routine appointment. The other needs to be seen today. Telling them apart from the description alone isn’t always possible, even for the person experiencing it.

Assessment

A slit-lamp examination lets Mr Aziz see the surface of the eye, the eyelids, and, where needed, the pressure and structures inside the eye.

2

Diagnosis

The pattern of pain, alongside what the examination shows, points to a specific cause rather than a general category.

3

Plan

Mr Aziz matches treatment to the actual cause, from simple lubrication to same-day referral, and explains it before anything happens.

Treatment Options

Treatment is matched to the underlying cause, not to the pain itself.

Lubrication and Rest

The right approach for surface irritation and mild dryness. Lubricating drops, reduced screen time, and avoiding known irritants resolve most cases within days.

Targeted Eyelid Treatment

Warm compresses, lid hygiene, or a short course of treatment for a stye or chalazion clears most eyelid-related pain without further intervention.

Same-Day Referral

Where assessment finds raised eye pressure, inflammation inside the eye, or a penetrating injury, treatment follows the same day. Timing matters more here than with almost any other cause on this list.

Frequently asked questions.

What causes eye pain?

Surface irritation, eyelid problems, inflammation inside the eye, and raised eye pressure are the four main categories, ranging from minor to a genuine emergency.

Sharp pain that worsens with blinking usually points to something on the surface of the eye, such as a foreign body or a small scratch on the cornea.

A dull ache felt behind the eye can come from inflammation inside the eye, raised eye pressure, or occasionally a cause outside the eye entirely, such as sinus pressure or migraine.

Yes, sometimes. Migraine and sinus pressure can both cause pain that’s felt around or behind the eye without the eye itself being the problem.

Sudden, severe pain, pain with blurred vision or halos around lights, or pain after an injury or chemical exposure all need same-day assessment.

Yes. Dry eye is one of the most common causes of gritty, burning surface pain, particularly when it builds gradually rather than starting suddenly.

Yes, a stye or chalazion causes localised, tender pain focused on the affected part of the eyelid, usually alongside visible swelling.

Sudden, severe pain with blurred vision can be a sign of acute angle-closure glaucoma, which needs same-day treatment. Chronic glaucoma, by contrast, is usually painless.

Sudden onset, severe intensity, and accompanying symptoms such as vision changes or nausea are the signs that separate an emergency from something that can wait for a routine appointment.

Yes, particularly if worn too long, fitted poorly, or if a foreign body gets trapped underneath one. Persistent pain after removing a lens should be assessed.

Sharp, stabbing pain usually points to the surface of the eye, most often a foreign body or a corneal abrasion.

Yes. Sinus pressure sits close to the eye socket and commonly causes an ache felt around or behind the eye without any problem in the eye itself.

Sudden severe pain, pain after a chemical splash or penetrating injury, or pain with vision loss warrants same-day emergency care, whether through A&E or an urgent ophthalmology appointment.

It tends to build gradually and fluctuate rather than resolve quickly, though targeted lubrication usually brings noticeable relief within days.

Yes, prolonged screen use or uncorrected refractive error can cause a dull ache, particularly by the end of the day, that usually settles with rest and, if needed, updated glasses.

A discussion of when the pain started and what it feels like, followed by a slit-lamp examination and, where relevant, a check of eye pressure and the back of the eye.

Yes, a corneal abrasion causes sharp, gritty pain that’s often worse in bright light and with blinking, and it typically heals within a few days with the right treatment.

Mild discomfort after surgery is common and expected. Pain that’s severe, worsening, or accompanied by vision changes should be reported promptly rather than waited out.

Allergies more often cause itching than true pain, though severe allergic reactions can bring a gritty, burning discomfort alongside redness and watering.

Pain that worsens specifically in bright light, known as photophobia, often points to inflammation on the surface of the eye or, less commonly, inside it, and is worth having assessed rather than managed with sunglasses alone.
