A subconjunctival hemorrhage typically clears up on its own within two weeks. Smaller spots may fade in just a few days, while larger bleeds can take three weeks or longer to fully disappear. The bright red patch on the white of your eye looks alarming, but in most cases it’s painless and harmless, requiring no treatment at all.
What the Healing Process Looks Like
The blood trapped beneath the clear membrane covering your eye (the conjunctiva) gets reabsorbed gradually, much like a bruise on your skin. In the first day or two, the spot is typically a vivid, solid red. Over the following days, it may spread slightly before it starts to shrink, which can be unsettling but is completely normal.
As healing progresses, the color shifts. The bright red fades to a darker red or maroon, then transitions through brownish and yellowish tones before disappearing entirely. You may notice a yellowish tint on the white of your eye in the final days of healing. The whole process mirrors what happens with a bruise on your arm or leg, just on a more visible surface.
What Causes the Bleeding
A subconjunctival hemorrhage happens when a tiny blood vessel on the surface of the eye breaks and leaks blood into the space between the conjunctiva and the white of the eye. Because the conjunctiva can’t absorb blood quickly, even a small amount of bleeding creates a noticeable red patch.
The most common triggers involve sudden spikes in pressure through the veins, often from everyday activities. Hard coughing, sneezing, vomiting, straining during a bowel movement, heavy lifting, and even vigorous exercise can all create enough pressure to burst a small vessel. Some people wake up with one and never identify a cause. Eye rubbing, contact lens irritation, and minor eye injuries are other frequent culprits.
High blood pressure and blood-thinning medications also raise your risk. People taking anticoagulants may develop larger hemorrhages that take longer to resolve. In rare cases involving anticoagulant use, the bleeding can become extensive enough to require medical intervention, though this is uncommon.
Why Some Take Longer to Heal
Several factors influence whether your hemorrhage clears in five days or lingers for three weeks. The size of the bleed matters most. A small dot-sized spot has far less blood to reabsorb than one that covers half the white of your eye. Your body clears the trapped blood at a relatively fixed rate, so larger hemorrhages simply need more time.
Blood-thinning medications, including aspirin, can both increase the initial size of the bleed and slow healing. If you take anticoagulants and notice a subconjunctival hemorrhage, there’s no need to stop your medication for a typical case, but it helps explain why the spot may stick around longer than the standard two-week window. One documented case of a patient on warfarin developed such severe hemorrhaging that it took several months to fully resolve, though that level of severity is extremely rare.
Treatment and What You Can Do
There is no way to speed up the reabsorption of blood from a subconjunctival hemorrhage. No eye drop, compress, or medication will make the redness disappear faster. Your body handles the cleanup on its own timeline.
If the area feels scratchy or mildly irritated, artificial tears can help soothe the surface. That’s comfort care, not treatment for the hemorrhage itself. Avoid rubbing the affected eye, as this could irritate the area or potentially cause additional bleeding. Beyond that, the only real remedy is patience.
When It Keeps Happening
A single subconjunctival hemorrhage is almost never a sign of something serious. But if you get them repeatedly without an obvious trigger like coughing or straining, it’s worth investigating. Recurrent hemorrhages can sometimes point to uncontrolled high blood pressure, a bleeding disorder, or very rarely, other underlying conditions that need attention.
For people who experience frequent unexplained episodes, a doctor may check blood pressure and run blood work to look at clotting function and blood cell counts. The goal is to rule out systemic issues that could be making blood vessels more fragile or more prone to bleeding.
Signs That Need Prompt Attention
Most subconjunctival hemorrhages are completely benign, but a few situations call for a closer look. If the hemorrhage followed a direct blow or injury to the eye, you should have it examined to rule out deeper damage. Pain in the eye (not just surface irritation), changes in your vision, bleeding that seems to be getting worse rather than better after the first couple of days, or blood that appears inside the colored part of the eye rather than on the white surface all warrant a prompt evaluation. A hemorrhage that hasn’t shown any improvement after three weeks is also worth having checked.
