Most red eyes are conjunctivitis, tiredness or a burst vessel, and settle. A few are the sort that damage sight if left. Here’s how to tell them apart, and what to do either way.
Same day — ring us now
Red and painful — not gritty, painful — especially if light hurts
Red with blurred vision that doesn’t clear with blinking
Red in a contact lens wearer (lens out first, then ring)
A red eye after something went in it — grit, a branch, a splash
One red eye with a feeling of pressure, nausea or a headache — this is A&E, not us
Can wait a day or two — but book
Both eyes red, sticky in the morning, otherwise comfortable: usually conjunctivitis. Warm water to clean the lids, don’t share towels, book if it’s not better in three days.
Itchy and red with a runny nose: allergy. Cold compress and an antihistamine drop from the pharmacy.
A bright red patch on the white with no pain and normal vision: a burst blood vessel. Alarming, harmless, gone in a fortnight.
Red rims that come and go for months: probably blepharitis or dry eye — not urgent, but worth a Dry Eye Assessment.
What we do
Twenty minutes with an optometrist: the front of the eye under the microscope, the pressure, and if needed the back of the eye. Most red eyes are treated on the spot with a prescription. If it needs the hospital, we ring them while you’re in the chair.
