What is blood shot?
Bloodshot eyes refer to redness of the eye, this is as a result of dilation and engorgement of blood vessels in the conjunctiva, the thin membrane that covers the white part of the eye and lines the inner surface of the eyelids.
This can be caused by several factors such as lack of sleep, allergies, dryness, eye infections, eye injuries, or underlying medical conditions like high blood pressure and diabetes.
What Can Cause Bloodshot?
The causes of bloodshot eyes are varied and can include:
Lack of sleep: Lack of sleep can cause eye fatigue and redness. Usually, the eyes turn red because the blood vessels on the surface of the eye get dilated or inflamed
Allergies: Allergic reactions to things like pet dander, dust, or pollen can cause inflammation and redness in the eyes.
Dry eyes: When the eyes are dry or irritated, the blood vessels in the conjunctiva can expand and become more visible.
Eye infections: Infections like conjunctivitis (pink eye) can cause redness in the eyes.
Eye injuries: Any type of injury to the eye can cause bloodshot eyes.
Contact lenses: Wearing contact lenses for extended periods can cause dryness and redness.

Alcohol and drug use: Excessive alcohol consumption or drug use can cause bloodshot eyes.
