Yes, coughing can sometimes hurt your eyes, although the harm is usually temporary and not serious.
Here's a more detailed explanation:
-
Subconjunctival Hemorrhage: The most common eye-related issue from coughing is a subconjunctival hemorrhage. This occurs when small blood vessels on the surface of the eye (conjunctiva) break. While it looks alarming (a bright red patch in the eye), it's generally painless and harmless. It happens because coughing increases pressure in the head and face, causing these delicate vessels to rupture.
-
Temporary Visual Disturbances: The pressure changes from coughing can also temporarily affect vision. Some people might experience:
- Bright Spots: Brief flashes of light.
- Blurry Vision: Short-term difficulty focusing.
-
Serious Injury is Rare: Direct injury to the eye from the physical act of coughing is highly unlikely. The discomfort someone feels is usually due to the pressure changes and the potential for a subconjunctival hemorrhage.
In summary, while a forceful cough can lead to minor, temporary eye issues like subconjunctival hemorrhages or visual disturbances due to pressure changes, serious or lasting damage is rare. If you experience persistent pain, vision changes, or other concerning symptoms, it's important to consult an eye doctor.
