A popped blood vessel in the eye looks alarming but almost never requires treatment. The bright red patch you’re seeing is called a subconjunctival hemorrhage, and it typically heals on its own within two weeks. No eye drops, no medications, no procedures. The blood is trapped beneath the clear surface layer of your eye and will gradually reabsorb, much like a bruise fading on your skin.
Why It Looks Worse Than It Is
The white of your eye is covered by a thin, clear tissue called the conjunctiva. Tiny blood vessels run through this tissue, and when one of them bursts, blood leaks into the space between the conjunctiva and the white of the eye. Because the blood has nowhere to go, it pools and spreads, creating that vivid red patch that can cover a large portion of the eye’s surface.
The condition is painless and does not affect your vision. You may not even notice it until you look in a mirror or someone else points it out. Some people feel a mild scratchy sensation on the surface of the eye, but that’s about it.
Common Causes
Sometimes there’s an obvious trigger, but often the blood vessel breaks for no clear reason at all. The most common causes include:
- Coughing or sneezing, especially forceful bouts
- Straining, such as heavy lifting, constipation, or vomiting
- Rubbing your eye too hard
- Minor trauma, like bumping or poking the eye
Blood-thinning medications and supplements (including aspirin, fish oil, and similar products) can make these vessels more fragile and more likely to bleed. High blood pressure is another contributing factor, particularly for people who experience repeated episodes.
What You Can Do at Home
There’s no way to speed up healing, but a few things can keep you comfortable while the blood clears. If the eye feels scratchy or irritated, preservative-free artificial tears can help lubricate the surface. Avoid rubbing the eye, which can worsen irritation or potentially cause more bleeding.
Skip contact lenses for a day or two if they’re uncomfortable. You can apply a cool compress (a clean cloth dampened with cool water) to the closed eye for a few minutes if it feels soothing, though this won’t change the healing timeline. Avoid aspirin or other blood thinners for minor aches during the healing period unless your doctor has prescribed them for another condition.
Healing Timeline
Most popped blood vessels heal within 7 to 14 days. The red patch won’t fade evenly. Instead, you’ll notice it changing colors over several days, shifting from bright red to orange, yellow, or greenish tones as the blood breaks down and gets reabsorbed. This color change is completely normal and actually a sign of healing.
Larger hemorrhages that cover more of the eye’s surface can take up to three weeks to fully clear. The speed depends partly on how much blood leaked and how quickly your body absorbs it. By 10 to 21 days after onset, most people see a full return to their normal eye appearance.
When a Red Eye Needs Attention
A straightforward popped blood vessel doesn’t hurt and doesn’t change your vision. If your situation involves any of the following, something more serious may be going on:
- Pain in the eye, not just surface irritation
- Changes in vision, including blurriness, double vision, or partial vision loss
- Blood that appears over your iris (the colored part of your eye) rather than on the white
- Bleeding after a significant impact to the eye or head
- Repeated episodes without an obvious cause
Blood pooling over the iris is a different condition called a hyphema, which involves bleeding inside the eye rather than on its surface. A hyphema causes pain and can threaten your vision. It requires prompt medical care, especially after trauma. The key distinction: a harmless popped vessel turns the white of the eye red and doesn’t hurt, while a hyphema makes it look like blood is sitting where your eye color is and causes noticeable pain.
If you keep getting popped blood vessels, it’s worth having your blood pressure checked. Recurring episodes can be a signal that blood pressure is running high or that a medication you’re taking is affecting clotting.
Reducing Your Risk Going Forward
You can’t prevent every popped blood vessel, but a few habits lower the odds. Be gentle when rubbing your eyes, or better yet, avoid rubbing them altogether. If allergies make your eyes itchy, use lubricating drops instead. Wear protective eyewear during sports or activities where your eye could get bumped.
Managing underlying conditions matters too. Keeping blood pressure in a healthy range reduces strain on the small vessels throughout your body, including those in your eyes. If you take blood thinners and notice frequent eye hemorrhages, mention it at your next appointment so your provider can evaluate whether an adjustment makes sense.
