Conjunctivitis, commonly known as "red eyes" or "pink eye," is a prevalent eye condition characterized by inflammation of the conjunctiva, a thin, clear tissue that covers the front surface of the eye and lines the inside of the eyelids. This eye ailment is a common reason for seeking medical attention, affecting millions of people worldwide each year. Conjunctivitis can be caused by various factors, Which including viral, bacterial infections, allergies, and irritants. Understanding the different causes of conjunctivitis is essential for proper diagnosis, treatment, and prevention.

Viral Infections:

Viral conjunctivitis is one of the most common causes of red eyes. It is primarily caused by viruses, such as adenoviruses and enteroviruses, which can spread easily from person to person. This type of conjunctivitis is highly contagious and is often associated with upper respiratory tract infections, such as the common cold. When infected with a virus, the conjunctiva becomes inflamed, leading to redness, watery discharge, itching, and sensitivity to light. Viral conjunctivitis can affect one or both eyes and may last for up to two weeks. Proper hygiene, including frequent handwashing and avoiding touching the eyes, can help prevent the spread of viral conjunctivitis.

Bacterial Infections:

Bacterial conjunctivitis is another common cause of red eyes. It occurs when bacteria, such as Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae, infect the conjunctiva. Bacterial conjunctivitis can be contracted through direct contact with infected eye secretions or by touching contaminated surfaces. It typically presents with redness, a thick yellow or green discharge, crusting of the eyelids (especially after waking up), and a gritty or scratchy sensation in the eyes. Unlike viral conjunctivitis, bacterial conjunctivitis can be treated with antibiotic eye drops or ointments. Completing the full course of prescribed antibiotics is essential to ensure effective treatment and prevent the development of antibiotic-resistant bacteria.


Allergic conjunctivitis is caused by an allergic reaction to substances or allergens like pollen, pet dander, dust mites, mold, or certain medications. When the conjunctiva comes into contact with these allergens, it triggers an immune response that leads to inflammation. Allergic conjunctivitis is not contagious and often affects both eyes simultaneously. It is associated with intense itching, redness, watery discharge, and swelling of the eyelids. Seasonal allergic conjunctivitis, Which commonly known as hay fever, may coincide with specific seasons when certain allergens are more prevalent. Avoiding exposure to allergens and using over-the-counter antihistamine eye drops can help manage allergic conjunctivitis. In severe cases, an eye care professional may prescribe stronger medications to alleviate symptoms.


Irritant conjunctivitis occurs when the eyes are exposed to irritants like smoke, air pollution, chlorine in swimming pools, harsh chemicals, or foreign bodies. This form of conjunctivitis is not contagious and is generally a result of external factors.

Avoiding exposure to irritants and using artificial tears to flush out the eyes can help alleviate symptoms and promote healing.
