A popped blood vessel in the eye, known medically as a subconjunctival hemorrhage, heals on its own without treatment. The bright red patch typically clears completely within 1 to 3 weeks as your body reabsorbs the trapped blood. There’s no way to speed up the process, but there are a few things you can do to stay comfortable and avoid making it worse.
Why It Looks Worse Than It Is
The blood vessels on the surface of your eye are tiny, fragile, and sit right on top of the white part of the eye with very little structural support around them. When one breaks, blood pools in the thin space between the outer membrane and the white of the eye. Because there’s no tissue to hide behind, even a small amount of blood creates a vivid, alarming-looking red patch. But the bleeding stays on the surface. It doesn’t reach the inside of the eye, and it doesn’t affect your vision.
You might notice the red spot spreading or shifting slightly during the first day or two. That’s normal. Over the following week or two, the color often changes from bright red to yellow-brown as the blood breaks down, similar to a bruise fading on your skin.
What You Can Do While It Heals
No drops, compresses, or home remedies will make the blood reabsorb faster. The goal is simply comfort and avoiding re-injury:
- Use preservative-free artificial tears. The hemorrhage itself doesn’t hurt, but some people feel a mild scratchiness or awareness of something on the eye’s surface. Lubricating drops can relieve that irritation.
- Avoid rubbing your eye. Rubbing can re-rupture the same vessel or break a new one, restarting the clock on healing.
- Skip aspirin and other blood-thinning pain relievers if you’re taking them for general aches (not a prescribed condition). These medications impair clotting and can make the hemorrhage larger or slower to resolve.
- Hold off on contact lenses until the redness clears. Contact lens wear increases friction on the eye’s surface, promotes dryness, and can contribute to further irritation.
What Causes a Blood Vessel to Pop
Often, the cause is surprisingly mundane. Anything that briefly spikes pressure in the veins of your head can rupture one of those delicate surface vessels: a hard sneeze, a coughing fit, straining during a bowel movement, vomiting, or heavy lifting. You might wake up with one and have no idea what triggered it.
Direct trauma is another common cause, especially in younger people. A poke to the eye, rubbing too hard, a foreign object, or rough contact lens handling can all do it. In older adults, spontaneous hemorrhages are more common and often tied to underlying conditions like high blood pressure, which is the single most consistently documented risk factor. Diabetes, high cholesterol, and bleeding disorders also weaken blood vessels or impair clotting, making ruptures more likely.
Certain medications raise the risk as well. Blood thinners like warfarin and heparin are the most obvious culprits, but daily aspirin and other antiplatelet drugs also increase susceptibility. If you take any of these and notice frequent eye hemorrhages, it’s worth mentioning to your doctor, though you should never stop a prescribed blood thinner on your own.
When a Red Eye Needs Attention
A straightforward popped blood vessel causes no pain and no vision changes. If your red eye comes with any of the following, something more serious may be going on:
- Eye pain or aching
- Blurred or reduced vision
- Blood that appears to be pooling in front of your iris (the colored part of your eye) rather than on the white
- Bleeding that followed a direct blow or injury to the eye
- Hemorrhages that keep recurring
Pain is the key differentiator. A painless red patch on the white of the eye is almost always a simple surface hemorrhage. But blood collecting in front of the iris, called a hyphema, causes pain and can threaten vision. Both conditions can happen at the same time after trauma, so any eye injury that produces visible bleeding warrants prompt evaluation.
Recurrent hemorrhages, even painless ones, can signal an undiagnosed problem. About 40% of spontaneous cases have no identifiable cause, but repeat episodes sometimes point to uncontrolled high blood pressure, diabetes, or a clotting disorder like hemophilia or von Willebrand disease. Your doctor may order blood work or check your blood pressure if this keeps happening.
Preventing Future Hemorrhages
You can’t eliminate the risk entirely, but a few practical steps reduce the odds. Wear protective eyewear during sports, yard work, or any activity that could send debris toward your face. If you wear contact lenses, keep them clean and replace them on schedule, since worn or dirty lenses increase surface friction and inflammation. Manage chronic conditions, particularly high blood pressure and diabetes, since both directly compromise blood vessel integrity over time.
If heavy lifting, straining, or chronic coughing tends to trigger your hemorrhages, those are worth addressing too. Treating constipation, managing a persistent cough, and using proper breathing technique during exercise all reduce the sudden spikes in venous pressure that pop those fragile vessels.
