A popped blood vessel in the eye looks alarming but is almost always harmless. The bright red patch on the white of your eye is called a subconjunctival hemorrhage, and most cases heal completely within two weeks without any treatment. Still, there are a few things you can do to help the healing process along and avoid making it worse.
Why It Happens
The white of your eye is covered by a thin, clear membrane packed with tiny blood vessels. When one of those vessels breaks, blood pools underneath the membrane and spreads across the surface, creating that vivid red blotch. It can happen from sneezing, coughing, straining on the toilet, vomiting, heavy lifting, or rubbing your eyes too hard. Sometimes it shows up after a rough night of sleep and you never identify a cause at all.
Certain medications increase the likelihood. Blood thinners like warfarin and daily aspirin reduce your blood’s ability to clot, making these small vessels more prone to visible bleeding. High blood pressure is another common contributor, as it puts extra pressure on delicate blood vessels throughout the body, including the ones in your eye.
Use Warm Compresses, Not Cold
Your instinct might be to reach for a cold pack, but warmth is actually more helpful here. A warm compress applied to the closed eye at least three times a day increases circulation to the area, which helps your body break down the pooled blood faster. Soak a clean washcloth in warm (not hot) water, wring it out, and hold it gently against the eye for five to ten minutes per session.
Cold compresses are better suited for allergic reactions and swelling. They won’t speed up reabsorption of the blood and may even slow it down by constricting blood flow to the area.
Avoid Straining During Healing
The same physical forces that caused the bleed can make it worse or trigger a new one before the vessel has fully repaired. During the first week or two, ease off anything that spikes your blood pressure or forces you to hold your breath. That includes heavy weightlifting, intense cardio, bending with your head below your waist (as in some yoga positions), and straining during bowel movements. If constipation is an issue, a mild stool softener can help you avoid bearing down.
You don’t need to stay in bed or skip work. Normal daily activities like walking, reading, and screen time are fine. Just avoid the kind of exertion that turns your face red.
Skip the Aspirin if You Can
Over-the-counter pain relievers like aspirin and ibuprofen thin the blood slightly and can prolong healing or increase the chance of rebleeding. If you need something for a headache or minor pain during this period, acetaminophen is a better choice since it doesn’t affect clotting. If you take a prescribed blood thinner or daily aspirin for a heart condition, don’t stop it on your own. That’s a conversation for your prescribing doctor.
What Healing Looks Like
The red patch won’t fade evenly. Over the course of one to two weeks, it goes through color changes similar to a bruise elsewhere on your body. Bright red shifts to darker red, then sometimes to a brownish or greenish tint. Toward the end, the white of your eye may look slightly yellow before returning to normal. This color progression is a sign that your body is actively reabsorbing the blood, not a sign of worsening.
The size of the initial bleed affects the timeline. A small spot may clear in under a week. A larger hemorrhage that covers most of the white of the eye can take the full two weeks or occasionally a bit longer.
Artificial Tears for Comfort
A popped blood vessel doesn’t usually hurt, but some people notice a mild scratchy or gritty sensation as the blood sits under the membrane. Preservative-free artificial tears can relieve that irritation. Use them as often as needed throughout the day. Avoid eye drops marketed as redness relievers, since those work by constricting blood vessels and won’t address this type of redness.
When the Cause Needs Attention
A single episode that heals on its own rarely signals anything serious. But certain situations call for a closer look. See a doctor if:
- You have eye pain. A subconjunctival hemorrhage is painless. Pain suggests a different or additional problem.
- Your vision changes. Blurring, double vision, or light sensitivity points to something beyond a surface bleed.
- The eye was injured. A direct hit to the eye can cause internal damage that isn’t visible from the outside.
- It keeps happening. Recurrent hemorrhages can be a sign of uncontrolled high blood pressure, a clotting disorder, or other underlying conditions that need bloodwork and a more thorough evaluation.
People on blood thinners who experience repeated eye bleeds may need their medication levels checked to make sure the dose hasn’t drifted too high. This is especially relevant for warfarin, where small shifts in dosing can have outsized effects on clotting.
Preventing Future Episodes
You can’t prevent every case, but you can reduce the odds. Keep blood pressure well managed if you have a history of hypertension. Wear protective eyewear during sports or activities where something could strike your face. Avoid rubbing your eyes aggressively, especially if they’re itchy from allergies. If heavy lifting is part of your routine, focus on steady breathing through each rep rather than holding your breath, which spikes pressure in the blood vessels of the head and eyes.
Contact lens wearers should make sure lenses fit properly and aren’t causing chronic irritation, since repeated rubbing to relieve lens discomfort is a common trigger people overlook.
