Eye pain — how to judge severity and urgency
Eye pain is one of the more urgent eye complaints, because a few of its causes can lose vision within hours. Severity + associated symptoms (nausea, vomiting, blurred vision, light sensitivity) are the key features that decide urgency.
What can cause this — and how each feels different.
Dry eye and eye strain
The commonest, mildest cause — a gritty ache after screen work that improves with rest and lubricants.
Corneal abrasion or foreign body
Sharp, sudden pain, watering, difficulty opening the eye. Usually needs a slit-lamp examination.
Corneal ulcer / keratitis
Severe pain with a red eye and blurred vision — an emergency, especially in contact-lens wearers.
Acute angle-closure glaucoma
Severe pain with headache, nausea and vomiting, and blurred vision with haloes — a genuine emergency.
Anterior uveitis
Deep aching pain, light sensitivity, red eye. Needs prompt slit-lamp diagnosis and treatment.
Post-operative infection
Pain that develops days-to-weeks after eye surgery is endophthalmitis until proven otherwise — always same-day.

Questions patients ask us most.
Can eye pain be a sign of glaucoma?
Chronic glaucoma is usually painless, but acute angle-closure glaucoma is exceptionally painful — a sudden severe eye pain with nausea is a red flag for it.
Why does my eye ache after screen work?
Prolonged near work reduces the blink rate, which dries the ocular surface. Regular breaks (20-20-20 rule) and lubricating drops usually help.
Should I use painkillers before seeing a doctor?
A single dose of paracetamol is fine, but avoid strong painkillers as they can mask worsening symptoms. If the pain is severe, come to the clinic first.
