Health Tip: Why Are My Eyes Red?
(HealthDay News) -- The sclera, or white area of the eye, appears red when blood vessels swell.
The U.S. National Library of Medicine mentions these possible causes of eye redness:
- Having a subconjunctival hemorrhage, or burst blood vessel, which could be triggered by straining or coughing.
- Having inflammation or infection of the eyelash follicles or membrane that lines the eyelids.
- Having an ulcer on the cornea (often caused by an infection).
- Having an allergy or the common cold.
- Having foreign matter in the eye.
- Having an injury to the eye.
- Having a bleeding disorder.
