Bloodshot eyes occur when the small blood vessels on the surface of the eye (sclera) become enlarged or irritated, leading to a red or pink appearance. This condition can vary in severity and may affect one or both eyes.
Causes: Common causes include lack of sleep, eye strain, dry eyes, exposure to
irritants like smoke or chemicals, and allergic reactions. Bloodshot eyes may also
result from more serious underlying issues such as infections like conjunctivitis,
uveitis, or glaucoma. Additional causes include trauma, prolonged use of contact
lenses, and systemic conditions like high blood pressure.
Symptoms: The primary symptom is visible redness in the whites of the eyes,
which may be accompanied by irritation, dryness, or a feeling of grittiness.
Depending on the cause, additional symptoms like watery eyes, swelling, pain, or
discharge may be present. If bloodshot eyes are accompanied by vision changes
or significant pain, it is important to seek medical attention promptly.
Treatment: Treatment for bloodshot eyes depends on the cause. For mild cases
related to dryness or irritation, over-the-counter artificial tears or antihistamine
drops can provide relief. If the condition stems from an infection or inflammation,
prescription eye drops or antibiotics may be necessary. In cases related to
underlying systemic conditions, treating the root cause is essential to resolving
the redness.
