What Is a Black Eye?

A black eye is bruising and swelling of the eyelids and skin around the eye after blunt trauma. Blood from damaged vessels collects under the skin, creating purple or blue discoloration that changes color as it heals. Vision is usually normal, but pain and puffiness are common. Careful assessment rules out more serious injuries inside the eye or skull.

What Causes a Black Eye?

Most black eyes result from sports injuries, falls, or minor accidents. Fractures of the orbital bones, nasal trauma, or surgical procedures can also cause periorbital bruising. Certain blood thinners and bleeding disorders increase bruising severity. A medical exam checks for ocular damage and facial fractures.

Why Bruising Appears Around the Eye

The skin around the eye is thin and rich in small blood vessels, so even minor impact allows blood to pool beneath the surface. The dark discoloration fades as the hemoglobin breaks down and the fluid reabsorbs.

When to See Your Doctor

You should see your eye doctor if you notice sudden or persistent changes in your vision such as blurriness, flashes of light, floaters, or eye pain. Redness, swelling, or discharge that does not improve with basic care also warrants a checkup. Even if symptoms seem mild, getting a professional evaluation can help detect problems early and prevent complications. Regular eye exams are also important to monitor your overall eye health and keep your vision clear.

How Is a Black Eye Treated?

Apply cold compresses for 10 to 20 minutes at a time during the first 24 to 48 hours to limit swelling, then switch to warm compresses to improve circulation. Keep the head elevated and avoid further trauma. Over the counter pain relief can help if approved by your clinician. Seek care if you have vision changes, severe pain, or persistent bleeding.

When Should I Worry About a Black Eye?

Red flags include double vision, significant vision loss, blood inside the eye, a cut on the eyelid margin, or difficulty moving the eye. These may indicate fractures, globe injury, or internal bleeding. Children with unexplained bruising require careful evaluation. Early treatment prevents complications.

How Long Does a Black Eye Last?

Bruising typically peaks within 48 hours and fades over 1 to 2 weeks as the blood breaks down and is reabsorbed. Discoloration may spread to the lower lid with gravity before resolving. Gentle care and rest support recovery. Protective eyewear can prevent future injuries.
