What It Means When You Have Blood in Your Eye

Having blood in your eye, a condition known medically as a subconjunctival hemorrhage can be startling. You might wake up one day, look in the mirror, and notice a bright red patch in the white part of your eye. This condition is usually harmless and resolves on its own, but it’s important to understand why it happens and when you might need to seek medical attention.

Understanding Subconjunctival Hemorrhage

What It Means When You Have Blood in Your Eye

What is a Subconjunctival Hemorrhage?

A subconjunctival hemorrhage tends to occur when a tiny blood vessel breaks just beneath the surface of your eye. This breakage leads to blood leaking under the conjunctiva, the transparent layer covering the white part of your eye. This results in a distinct red or blood-colored patch on your eye.

Why Does it Happen?

There are several reasons why these blood vessels might break:

  1. Minor Injury or Strain: Simple actions like coughing, sneezing, straining, vomiting, or even rubbing your eye too hard can cause this type of hemorrhage.
  2. High blood pressure: In some cases, high blood pressure can lead to weakened blood vessels, which might burst more easily.
  3. Blood-Thinning Medications: If you’re taking medications like aspirin or anticoagulants, they can increase the likelihood of these hemorrhages.
  4. Spontaneous Breakage: Sometimes, these vessels can break without any apparent cause, especially in the elderly.


The most obvious symptom is the red patch in your eye. However, there are usually no other symptoms like pain or vision changes. You might not even know it’s there until you look in a mirror or someone else points it out.

When to See a Doctor

While a subconjunctival hemorrhage is often not serious, there are instances when you should consult a healthcare professional:

  1. Recurrent Hemorrhages: If this happens frequently, it could indicate an underlying health issue.
  2. Pain or Vision Changes: If you experience pain, changes in vision, or light sensitivity, it’s crucial to seek medical advice.
  3. Blood Disorders: If you have a known blood disorder or are taking blood thinners, it’s wise to inform your doctor.
  4. Eye Trauma: If the red eye is accompanied by an injury, immediate medical attention is needed.

Treatment and Recovery

Home Care

In most cases, a subconjunctival hemorrhage doesn’t require treatment. Here are a few tips for taking care of your eye while it heals:

  • Avoid Rubbing: Try not to rub your eye, as this can cause further irritation.
  • Artificial Tears: If your eye feels uncomfortable, over-the-counter artificial tears can provide relief.
  • Rest and Hydrate: Ensure you’re getting enough rest and staying hydrated.

Healing Time

Typically, the blood in your eye will clear up on its own within two weeks. The red patch may change colors, much like a bruise does before it completely fades away.

In summary, having blood in your eye is usually not a cause for alarm. Most of the time, it’s just a minor rupture of a blood vessel that heals on its own. However, if you’re experiencing additional symptoms or have concerns, it’s always best to consult with a healthcare professional for peace of mind and proper guidance.
