Seeing a bright-red patch on the white of your eye can be alarming. This is usually conjunctival bleeding — a subconjunctival haemorrhage — where a tiny surface blood vessel breaks and leaks under the clear conjunctiva. It looks dramatic but, in most cases, it doesn’t hurt, doesn’t affect vision and isn’t an infection. Think of it as a bruise on the eye’s surface: it almost always settles on its own over several days to a couple of weeks.
This guide sets out practical conjunctival bleeding treatment you can do at home: simple self‑care to soothe irritation, which over‑the‑counter drops are safe (and which to avoid), what not to do while it heals, and the usual recovery timeline. You’ll also find clear advice on when to see a doctor, urgent warning signs, how clinicians confirm the diagnosis, and how to lower your risk of repeat episodes. Let’s start with what causes it and who’s most at risk.
What causes conjunctival bleeding and who is at risk
Most cases happen when a small surface vessel bursts after brief pressure spikes from coughing, sneezing, straining on the toilet, vomiting, heavy lifting or eye rubbing; minor eye trauma and contact lenses can do it too. Risks rise with older age, high blood pressure, diabetes, blood‑thinning medicines, blood‑clotting disorders, and recent eye surgery — yet many cases are idiopathic.
Signs to look for and how it typically presents
Conjunctival bleeding usually shows as a sharply outlined, bright‑red patch on the white of the eye. There’s no pain, discharge or change in vision; at most a mild scratchy or itchy feeling. The blood sits under the clear surface, so it won’t move or wipe away, and over days it may spread a little then yellow as it fades.
Home care for conjunctival bleeding (subconjunctival haemorrhage)
Most conjunctival bleeding needs no active treatment. The body reabsorbs the blood by itself, usually within 1–2 weeks (larger patches can take a little longer). Home care focuses on comfort and protecting the eye’s surface while it heals.
- Use lubricating “artificial tears”: Preservative‑free drops as needed (up to several times a day) can ease any scratchy or itchy feeling.
- Apply a cool compress for comfort: A clean, cool cloth over closed lids for 5–10 minutes can soothe irritation.
You can carry on with normal daily activities. Stick to simple lubrication for conjunctival bleeding treatment unless a clinician advises otherwise.
Which eye drops are safe to use (and which to avoid)
For conjunctival bleeding treatment, the goal is comfort, not “clearing” the blood. The patch will resolve on its own, so choose simple lubrication and skip medicines you don’t need.
- Safe to use: Artificial tears/lubricating drops as needed to ease any scratchy or itchy feeling. Choose non‑medicated OTC tears.
- Usually not needed (avoid unless prescribed): Antibiotic or steroid eye drops — there’s no infection or inflammation to treat in an uncomplicated subconjunctival haemorrhage.
- Skip “get‑the‑red‑out” drops: Decongestant/whitening drops don’t speed healing and are unnecessary.
- Contact lens solutions aren’t a substitute: Use proper lubricating tears, not lens cleaner or disinfectant.
What not to do while your eye heals
While your eye heals, be gentle. Don’t rub or poke it (the blood won’t wipe away). If you wear contact lenses, switch to glasses until the eye feels normal to reduce friction. Go easy on heavy lifting and straining for a few days. Avoid “redness‑relief” decongestant drops, and never stop prescribed blood thinners without medical advice — use simple lubricating tears for comfort.
Recovery time: how long it takes and what to expect as it clears
Recovery is gradual as your body reabsorbs the blood. Most subconjunctival haemorrhages clear within 1–2 weeks; some take a few weeks if the patch is large. Expect the colour to evolve like a fading bruise — bright red to dull red, then yellowish — without affecting vision. Comfort usually improves with simple lubricating drops; no specific conjunctival bleeding treatment speeds the process.
- Not fading after ~2 weeks: If the patch hasn’t begun to lighten, or seems larger, check in with your GP or optometrist.
- Recurring episodes: If this keeps happening, ask about blood pressure checks and blood‑clotting tests.
When to seek medical care
Most subconjunctival haemorrhages settle without treatment. Seek medical advice if you’re unsure it’s a simple subconjunctival bleed, or if any of the following apply — getting timely guidance can refine your conjunctival bleeding treatment plan and rule out other causes.
- Eye pain or significant discomfort
- Any change in vision (blur, shadow, double vision)
- Discharge or swelling (it shouldn’t produce discharge)
- Recent eye injury or surgery
- Not improving after about 2 weeks or the red area is enlarging
- Frequent recurrences, easy bruising/bleeding, or you’re on blood thinners (don’t stop them; speak to your doctor)
When it’s an emergency and you should act now
Most subconjunctival haemorrhages aren’t emergencies. But certain red flags suggest something more serious and need same‑day assessment. If any of the following occur, go to an emergency department or seek urgent eye care today.
- Severe eye pain
- Any vision change (blur, shadow/“curtain”, double vision or vision loss)
- After eye or head injury, including sports or workplace trauma
- Blood pooling in front of the iris (a dark, fluid line) suggesting a hyphema
- Signs of severe eye trauma or other facial injuries alongside the red eye
How clinicians diagnose conjunctival bleeding
Diagnosis is clinical: a clinician confirms a well‑demarcated red patch under the conjunctiva with normal vision and no discharge. They ask about coughing/straining, minor trauma, lenses and medicines, check blood pressure, and if episodes recur or bruising is easy, may order blood tests. Pain, vision change or injury triggers assessment for other conditions (e.g., hyphema).
Preventing future episodes
While many subconjunctival haemorrhages are random, a few habits lower your risk. Avoid rubbing your eyes; use preservative‑free artificial tears if they’re dry or irritated. Keep contact lenses clean and well‑fitted, and wear protective eyewear for sport or work. Manage blood pressure, treat coughs and constipation, and avoid heavy straining. If bleeds recur, see your doctor to review medicines and consider clotting tests — alongside simple conjunctival bleeding treatment for comfort.
Special situations: blood thinners, diabetes and high blood pressure
If you’re on anticoagulants or antiplatelets (e.g., warfarin, aspirin), or you have diabetes or high blood pressure, the conjunctival bleeding treatment is the same: simple lubrication for comfort. Don’t stop blood thinners unless your doctor advises it. If bleeds recur, organise a blood pressure check and consider medication review and clotting tests. Well‑controlled BP and glucose reduce recurrence risk.
Advice for contact lens wearers
Contact lenses increase surface friction, so switch to glasses until the eye looks white again and feels normal. Use preservative‑free artificial tears for comfort. When you restart, put in a fresh, disinfected pair with clean hands, replace the case, avoid sleeping in lenses or overwear, and book a fit/hygiene review if episodes recur.
After eye injury or surgery: how management differs
After trauma or operations, don’t treat it as a routine subconjunctival haemorrhage. Seek same‑day clinical review to exclude corneal injury, globe trauma or hyphema. Follow your surgeon’s post‑op plan; report any new redness, pain or vision change. Use only lubricant drops unless advised; avoid rubbing, contact lenses and heavy exertion. If on blood thinners, don’t stop them without medical advice.
How conjunctival bleeding differs from conjunctivitis and other “red eye” causes
Subconjunctival haemorrhage looks dramatic but isn’t like infectious or inflammatory “red eye”. It’s a sharply bordered, bright‑red patch with no pain, discharge or vision change, and it resolves unaided. Other causes usually bring discomfort, light‑sensitivity, discharge or blur and need specific assessment rather than simple conjunctival bleeding treatment.
- Conjunctivitis: diffuse pink/red, gritty itch, discharge/crusting; contagious.
- Corneal abrasion/keratitis: pain, photophobia, tearing or blur — urgent.
- Uveitis or scleritis: deep ache, light sensitivity, reduced vision — same‑day.
- Acute angle‑closure glaucoma or hyphema: severe pain/vision loss — emergency.
Frequently asked questions
Here are quick answers to the questions patients ask most about conjunctival bleeding treatment and recovery. Use them as a guide — seek care sooner if anything doesn’t fit the usual, painless “bruise on the eye” pattern.
- Is it dangerous? Usually harmless and not an infection. See a doctor if there’s pain, vision change or recent injury.
- How long will it last? Most clear in 1–2 weeks; larger patches can take a few weeks.
- Which drops should I use? Artificial tears for comfort. Medicated drops (antibiotic or steroid) aren’t needed unless prescribed.
- Can I work or exercise? Yes, normal activity is fine. Avoid heavy lifting/straining for a few days and don’t rub.
- What about contact lenses? Switch to glasses until the eye looks and feels normal; restart with clean lenses.
- Will it keep happening? It can. Roughly 1 in 10 recur without risk factors; if frequent, see your GP for blood pressure and, if needed, clotting tests — especially if you’re on blood thinners.
