Red eye, medically known as conjunctivitis, is a common condition characterized by inflammation of the thin, transparent layer of tissue covering the white part of the eye and lining the inner surface of the eyelids (conjunctiva). This inflammation leads to the blood vessels in the conjunctiva becoming dilated and more visible, giving the eye a reddish appearance.
Red eye symptoms
The symptoms of red eye can vary depending on the underlying cause but often include:- Redness
- Itching or irritation
- Excessive tearing
- Grittiness
- Yellowish discharge
- Sensitivity to light
What causes red eye?
Red eye can be caused by various factors, including infections, allergies, environmental irritants, contact lens overwear and underlying health conditions. Viral or bacterial infections, such as those associated with the common cold or flu viruses, can lead to redness, discharge, and discomfort in the eyes. Allergic reactions to allergens like pollen, dust mites, or pet dander can trigger inflammation of the conjunctiva, resulting in redness and itching. Additionally, underlying health issues such as dry eye syndrome, autoimmune disorders, or systemic infections may contribute to the development of red eye symptoms.Diagnosing your condition
