While it is natural to worry about the sight of bloodshot eyes, understanding the underlying causes can help us address the issue effectively. In this blog post, we will delve into the various reasons why red eyes occur and explore potential treatments to alleviate discomfort and restore clarity to your eyes.



One of the most common culprits behind red eyes is conjunctivitis, commonly known as pink eye. This contagious condition causes inflammation of the thin, clear tissue that covers the white part of the eye and the inside of the eyelid.

Viral, bacterial, and allergic conjunctivitis can all lead to redness, itching, tearing, and discharge. Treating this condition usually involves proper hygiene measures, lubricating eye drops, and sometimes prescription medication.



Dry Eyes

Dry eyes occur when the eyes do not produce enough tears or the tears evaporate too quickly. Excessive screen time, environmental factors, autoimmune diseases, and age can contribute to dry eye syndrome.

Redness, irritation, a gritty feeling, and blurred vision are common symptoms. Artificial tears, lifestyle modifications, and in some cases, medicated eye drops or ointments may help alleviate the symptoms.
