A broken blood vessel in the eye, known as a subconjunctival hemorrhage, heals on its own without treatment. Most cases resolve within 7 to 14 days, though larger spots can take up to 21 days to fully clear. The bright red patch looks alarming, but it’s painless, doesn’t affect your vision, and requires no medical intervention in the vast majority of cases.
That said, you probably want to know what you can do to stay comfortable, what the healing process actually looks like, and when the redness signals something more serious. Here’s what to expect.
Why There’s No Way to Speed Up Healing
When a tiny blood vessel breaks beneath the conjunctiva (the clear membrane covering the white of your eye), blood pools in the space underneath. Your body reabsorbs that trapped blood gradually, the same way it breaks down a bruise on your skin. There’s no drop, medication, or procedure that accelerates this process. The blood simply has to be cleared by your body’s own cleanup system, cell by cell.
This is why eye doctors typically don’t prescribe anything for it. The condition is self-limiting, meaning it runs its course and resolves completely without leaving any damage behind.
What the Healing Timeline Looks Like
In the first day or two, you’ll see a vivid, bright red patch on the white of your eye. It may even spread slightly before it starts to shrink, which is normal. Over the next several days, the red shifts to darker shades, then transitions through orange, yellow, and eventually fades entirely as your body breaks down the hemoglobin in the trapped blood. This color progression follows the same pattern as a bruise on your arm.
Most people see full resolution between 10 and 21 days after the hemorrhage first appears. Smaller spots clear faster. Larger hemorrhages that cover more of the white of the eye take longer. If you take blood thinners or are older, expect healing to sit at the longer end of that range.
What You Can Do for Comfort
While you can’t speed up the healing, you can manage the mild irritation that sometimes accompanies it. Artificial tears (available over the counter) help soothe any scratchy or itchy sensation. Use them as needed throughout the day.
Avoid rubbing your eye, even if it feels slightly irritated. Rubbing can aggravate the area or potentially cause another small vessel to break. If you wear contact lenses, give your eyes a rest with glasses for a few days if the lens feels uncomfortable against the affected area.
Common Triggers
A broken blood vessel in the eye often happens after sudden physical strain that briefly spikes pressure in the tiny vessels of the conjunctiva. Sneezing, coughing, vomiting, heavy lifting, and straining during a bowel movement are all common triggers. Sometimes it happens during sleep and you wake up with it, never knowing the exact cause.
Other contributing factors include high blood pressure, blood-thinning medications like warfarin or aspirin, eye trauma (even minor, like aggressive rubbing), and contact lens wear. Warfarin is one of the most commonly prescribed blood thinners in North America and is a known cause of spontaneous eye hemorrhages, though these cases still typically resolve on their own within 5 to 10 days.
In many cases, there’s no identifiable trigger at all. A vessel simply breaks. This is especially common in older adults whose blood vessels are more fragile.
Reducing the Chance of Recurrence
If this keeps happening, it’s worth looking at what might be contributing. Uncontrolled high blood pressure is one of the most important factors to address, since it puts chronic stress on small blood vessels throughout the body, including in the eyes. If you haven’t had your blood pressure checked recently, this is a good reason to do so.
If you take blood thinners or aspirin regularly, mention the eye hemorrhage to the prescribing doctor. They may want to check your clotting levels to make sure your medication is in the right range. Don’t stop taking prescribed blood thinners on your own.
For strain-related episodes, practical steps help: treat chronic coughs, eat enough fiber to avoid constipation, and use proper breathing technique during heavy lifting rather than holding your breath and bearing down.
When Red Eyes Signal Something More Serious
A standard subconjunctival hemorrhage is painless and doesn’t affect your sight. If your situation includes any of the following, it’s a different condition and needs prompt evaluation:
- Pain in the eye. A painless red patch is typical of a broken surface vessel. Pain suggests something deeper may be involved.
- Blurry, clouded, or blocked vision. A subconjunctival hemorrhage doesn’t interfere with vision because the blood sits on the outside of the eye, not inside it.
- Bleeding inside the eye itself. If you see blood pooling in the colored part of your eye (between the cornea and iris), this is called a hyphema. It’s usually caused by an injury and requires immediate attention from an ophthalmologist.
- Sensitivity to light. This, combined with eye pain, can indicate a hyphema or other internal eye problem.
- Recurrent hemorrhages without an obvious cause. Frequent episodes may point to an underlying bleeding disorder or poorly controlled blood pressure that needs investigation.
The key distinction is straightforward: a subconjunctival hemorrhage looks dramatic but feels like nothing. If your eye hurts or your vision changes, that’s a different situation entirely.
What to Expect Day by Day
Days 1 through 3 are usually the most visually striking. The red patch is at its brightest and may even expand slightly as the pooled blood spreads beneath the membrane. This doesn’t mean the hemorrhage is getting worse. It’s just the blood distributing across the available space.
By days 4 through 7, you’ll likely notice the edges of the red area beginning to lighten, often turning yellowish or brownish. The center may still look red. This is the active reabsorption phase, and it’s a clear sign healing is progressing normally.
By days 10 through 14, most small to moderate hemorrhages are nearly or completely resolved. Larger ones may retain a faint yellowish tint for up to three weeks before the eye returns to its normal white appearance. Once it clears, there’s no scar, no lasting discoloration, and no effect on your eye health.
