If you’ve ever noticed a bright red spot on the white part of your eye, it’s natural to be alarmed. Broken blood vessels in the eye, also known as subconjunctival hemorrhages, are usually harmless and resolve on their own within two weeks.

Although they rarely indicate a serious issue, understanding the causes, signs to watch for, and steps to take can help you feel more at ease. Regular eye exams at Queensway Optometric Centre can help identify any underlying concerns and ensure your overall eye health is monitored effectively.

While these red spots might look dramatic, they often cause no discomfort or long-term harm. Nevertheless, recognizing when a broken blood vessel might signify something more serious is crucial for peace of mind and proactive care. Keeping your eyes healthy begins with understanding the basics.

What Causes Broken Blood Vessels in Your Eye?

Broken blood vessels in the eye happen when tiny blood vessels beneath the conjunctiva—the clear surface of the eye—rupture. This rupture allows blood to spread across the sclera, creating a vivid red appearance. Common causes include:

  • Straining: Activities like heavy lifting, sneezing, or intense coughing can increase pressure in the blood vessels, causing them to break.
  • Injury: Direct trauma to the eye, vigorous rubbing, or exposure to foreign objects can lead to a rupture.
  • Health conditions: Conditions such as high blood pressure, diabetes, or blood-clotting disorders may weaken blood vessel walls, making them more prone to breaking.
  • Medications: Certain blood thinners, such as aspirin or anticoagulants, can increase the likelihood of bleeding under the conjunctiva.

Frequent occurrences of broken blood vessels might warrant a closer look at your overall health. Speak to your optometrist if you’re concerned about these symptoms. Identifying triggers can also help you minimize recurrence.

Can Broken Blood Vessels in Your Eye Be Dangerous?

In most cases, broken blood vessels in the eye are not dangerous. They often heal on their own without treatment. However, in rare cases, they could signal underlying health problems, such as:

  • High blood pressure: Recurrent broken blood vessels might indicate poorly managed hypertension.
  • Blood disorders: Conditions affecting your blood’s ability to clot, such as hemophilia or platelet deficiencies.
  • Trauma or infections: Direct injuries or infections to the eye can result in persistent or worsening redness.

While the majority of cases resolve naturally, it’s important to seek professional care if you’re experiencing other symptoms like pain, blurred vision, or swelling. At Queensway Optometric Centre, we offer comprehensive evaluations to identify any underlying issues and ensure your peace of mind.

How Do You Pop a Blood Vessel in Your Eye?

A broken blood vessel can occur from seemingly harmless everyday actions. Some common triggers include:

  • Sneezing or coughing: Sudden, forceful actions that increase pressure in the head and eyes.
  • Eye rubbing: Rubbing your eyes aggressively, especially when they’re irritated or itchy.
  • Vomiting or physical strain: Excessive physical effort, such as during intense exercise or heavy lifting, can momentarily raise blood pressure and cause a vessel to rupture.

Even though broken blood vessels often occur accidentally, reducing your exposure to these triggers can help minimize their frequency. Understanding what causes them is key to maintaining healthy eyes.

When Should I Worry About Broken Blood Vessels in My Eye?

While most cases are harmless, certain symptoms may signal a more serious condition that requires attention. You should consult an optometrist if:

  • The redness covers a large area or spreads beyond the sclera: This could indicate a deeper hemorrhage or injury.
  • You experience pain, discomfort, or changes in vision: These symptoms may suggest additional complications, such as corneal damage or inflammation.
  • The redness does not improve or disappear after two weeks: Prolonged redness could indicate an underlying issue that needs treatment.
  • Recurrent episodes: Frequent broken blood vessels may be a sign of high blood pressure or other systemic conditions.

At Queensway Optometric Centre, we prioritize your eye health and are equipped to address these concerns with care and precision. Early intervention can help preserve your vision and overall well-being.

How to Heal Popped Blood Vessels in My Eye

Typically, no treatment is necessary, as the condition resolves on its own. However, there are steps you can take to promote healing and comfort:

  • Using lubricating eye drops: Artificial tears can relieve irritation and keep your eyes moisturized.
  • Avoiding eye strain: Limit screen time, take regular breaks, and ensure proper lighting when reading or working.
  • Protecting your eyes: Avoid rubbing them and use protective eyewear, such as sunglasses with UV protection, during activities like sports, yard work, or exposure to strong winds.

While these measures can help your eyes feel more comfortable, persistent symptoms should always be evaluated by a professional. 

The Importance of Regular Eye Exams
