A popped blood vessel in the eye, known medically as a subconjunctival hemorrhage, heals on its own without treatment. Most cases clear up within two weeks, though larger spots can take up to three weeks. There’s no way to speed up the process, but there are steps you can take for comfort and things worth watching for while it resolves.
Why It Happens
The white of your eye is covered by a thin, clear membrane called the conjunctiva. Tiny blood vessels run through it, and when one breaks, blood pools underneath and creates that alarming red patch. The blood is trapped in a small space, which is why it looks so vivid even when the amount of bleeding is tiny.
Common triggers include sneezing, coughing, vomiting, straining during a bowel movement, heavy lifting, or rubbing your eyes. Sometimes it happens during sleep for no obvious reason. Eye injuries, contact lens irritation, and even a particularly forceful sneeze can be enough to rupture one of these fragile vessels.
Certain medications increase the likelihood. Blood thinners like warfarin, rivaroxaban, dabigatran, and apixaban all reduce your blood’s ability to clot, making vessels more prone to bleeding. Aspirin and other over-the-counter anti-inflammatory drugs can have a similar effect. Herbal supplements like ginkgo biloba and fish oil also thin the blood. If you take any of these and notice popped vessels more than once, it’s worth mentioning to your doctor, though you should never stop a prescribed blood thinner on your own.
Chronic conditions play a role too. High blood pressure puts extra stress on small blood vessels throughout the body, including those in the eye. Diabetes can weaken vessel walls over time. If you’re getting recurrent hemorrhages, uncontrolled blood pressure or blood sugar may be a contributing factor.
What Healing Looks Like
The red spot typically looks worst in the first day or two. It may even spread slightly before it starts to improve, which is normal. Over the following 10 to 21 days, the color shifts as your body reabsorbs the blood. Expect bright red to fade to darker red, then to a brownish or yellowish tinge before finally clearing. The progression is similar to watching a bruise on your skin cycle through colors.
Larger hemorrhages that cover a bigger area of the white of the eye simply take longer to reabsorb. A small dot might be gone in a week. A patch that covers half the visible white could linger closer to three weeks. The timeline varies from person to person, but the process is the same.
Home Care for Comfort
You can’t make the blood reabsorb faster, but you can keep the eye comfortable while it heals. Preservative-free artificial tears (available at any pharmacy) help if the eye feels dry or mildly scratchy. Some people notice a slight gritty sensation from the raised patch of blood, and lubricating drops ease that.
Cool compresses applied gently over a closed eyelid can feel soothing in the first day or two. After the first 48 hours, some eye care professionals suggest switching to warm compresses, which may help encourage blood reabsorption, though evidence for this is limited. Avoid rubbing the affected eye. Rubbing can re-irritate the area or even cause additional vessel breakage.
If you wear contact lenses, consider switching to glasses until the redness clears. Contacts can trap irritants against the healing tissue and slow your comfort, even if they don’t technically slow the healing itself.
What to Avoid During Recovery
Aspirin and ibuprofen can interfere with clotting and potentially prolong the appearance of the hemorrhage. If you don’t need these medications for another condition, it’s reasonable to avoid them while the eye heals. Acetaminophen (Tylenol) is a better option for general pain relief during this time since it doesn’t affect clotting.
Straining of any kind can raise pressure in the tiny vessels of the eye. If heavy lifting, intense exercise, or straining during bowel movements triggered the hemorrhage in the first place, easing up for a few days gives the broken vessel time to seal. Staying hydrated and eating enough fiber can reduce straining.
When It Needs Medical Attention
A straightforward subconjunctival hemorrhage is painless and doesn’t affect your vision. If either of those things isn’t true, something else may be going on. See a healthcare provider if you have eye pain (beyond mild scratchiness), any change in your vision, or if the hemorrhage resulted from an eye injury. Trauma to the eye can cause bleeding in deeper structures that needs evaluation.
Frequent recurrences also warrant a visit. A single popped vessel once or twice a year is usually nothing to worry about. But if it keeps happening, blood work can check for clotting disorders, and a blood pressure reading can reveal hypertension you may not have known about. Easy bruising elsewhere on your body alongside recurrent eye hemorrhages is another signal to get checked.
Reducing Your Risk Going Forward
You can’t prevent every broken blood vessel, but a few habits lower the odds. Managing blood pressure through diet, exercise, and medication (if prescribed) protects small vessels everywhere, including the eyes. Wearing protective eyewear during sports or yard work prevents trauma-related bleeds. If dry eyes cause you to rub frequently, using artificial tears daily can break that cycle.
For people prone to forceful sneezing or coughing, treating underlying allergies or respiratory infections promptly may help. And if you strain during bowel movements regularly, addressing that with dietary changes is one of the simplest preventive steps available. These are small adjustments, but they target the most common triggers directly.
