Pink eye, also known as conjunctivitis, is a common and highly contagious eye infection that affects millions of people worldwide. It is characterized by inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and the inner surface of the eyelids. The condition is often accompanied by symptoms such as redness, itching, burning, and discharge, which can range from a thin, watery secretion to a thick, yellowish or greenish pus.
Understanding Pink Eye
Pink eye can be caused by a variety of factors, including viral or bacterial infections, allergies, and irritants such as chemicals or dust. The most common types of pink eye are viral conjunctivitis, bacterial conjunctivitis, and allergic conjunctivitis. Viral conjunctivitis is the most common form of the condition and is often accompanied by a watery discharge. Bacterial conjunctivitis, on the other hand, is typically characterized by a thicker, more purulent discharge. Allergic conjunctivitis is usually seen in people who have a history of allergies and is often accompanied by other symptoms such as sneezing, runny nose, and itchy skin.

Viral Conjunctivitis
Viral conjunctivitis is the most common form of pink eye and is often accompanied by a watery discharge. It is highly contagious and can spread quickly from person to person. The condition is usually caused by a viral infection, such as the common cold or flu, and can also be spread through contact with an infected person’s hands, surfaces, or other objects. Symptoms of viral conjunctivitis typically include redness, itching, burning, and a watery discharge, and can last for several days to a week or more.
| Type of Conjunctivitis | Causes | Symptoms |
|---|---|---|
| Viral Conjunctivitis | Viral infections, such as the common cold or flu | Redness, itching, burning, watery discharge |
| Bacterial Conjunctivitis | Bacterial infections, such as staphylococcus or streptococcus | Redness, itching, burning, thick, purulent discharge |
| Allergic Conjunctivitis | Allergies, such as hay fever or dust mites | Redness, itching, burning, watery discharge, sneezing, runny nose |
Treatment and Prevention
Treatment for pink eye depends on the underlying cause of the condition. For viral conjunctivitis, treatment typically involves self-care measures, such as applying warm compresses to the eyes, using over-the-counter pain relievers, and avoiding contact with others to prevent the spread of the infection. For bacterial conjunctivitis, treatment usually involves antibiotics, either in the form of eye drops or ointment. Allergic conjunctivitis can be treated with antihistamines, mast cell stabilizers, or corticosteroids, depending on the severity of the symptoms.
Prevention is key to avoiding pink eye. Practicing good hygiene, such as washing your hands frequently, avoiding touching your eyes, and avoiding sharing personal items, such as towels or makeup, can help reduce the risk of contracting the infection. Wearing protective eyewear, such as goggles or masks, when engaging in activities that may expose you to irritants or allergens can also help prevent pink eye.
