What Causes A Broken Blood Vessel In The Eye?

Violent Coughing Or Sneezing

It's possible for a blood vessel to rupture from violent coughing or sneezing. Both of these actions are forceful and are oftentimes involuntary. Coughing is meant to keep the throat clear and will oftentimes occur because of the flu or a cold. Chronic bouts of coughing tend to last for two to three weeks. Sneezes are similar in that they are designed to remove irritants from the throat or nose. While the act of sneezing is beneficial to the body's health, it is also entirely involuntary and is oftentimes forceful. Bright lights, exposure to cold, and irritants like pepper are known to heighten the possibility of sneezing. When the act of coughing or sneezing is particularly violent, it's possible the force will be high enough to cause a blood vessel in an individual's eyes to rupture.
