blood shot eye causes review

Bloodshot eyes, or red eyes, can be caused by various factors, including allergies, blepharitis, chalazion or stye, eye dryness, sun exposure, dust or other particles in the eye, infection, injury, and broken blood vessels. When the tiny blood vessels in the eye get larger or inflamed, the eyes appear red or bloodshot. Serious causes of red eyes that require medical intervention include conjunctivitis, blepharitis, and subconjunctival hemorrhage. Conjunctivitis, also known as pink eye, may be the result of viral infections, bacterial infections, allergies, or environmental irritants. Blepharitis is an inflammation of the eyelids, causing them or the eyes to appear red and swollen. Subconjunctival hemorrhage can occur when a blood vessel breaks, causing blood to leak onto the surface of the eye, leading to a red appearance. It often resolves on its own but may require medical attention in certain cases, such as for people taking blood thinners or those with diabetes or hypertension
