This guide will delve into the causes, symptoms, treatments, and the importance of professional evaluation for pink eye.
What is Pink Eye?
Definition and Overview
Pink eye is an inflammation or infection of the conjunctiva, leading to noticeable redness and discomfort. It can affect one or both eyes and is often associated with various symptoms ranging from mild irritation to severe pain and visual disturbances.

Causes of Pink Eye
Viral Infections
The most common cause of pink eye is viral infections. Viral conjunctivitis is highly contagious and can spread rapidly in places like schools and workplaces.
Bacterial Infections
Bacterial conjunctivitis is another common cause, often resulting in a thick, yellow discharge. It can spread through direct or indirect contact with the infected person’s eye secretions.
Allergies
Allergic conjunctivitis occurs due to reactions to allergens like pollen, dust, or pet dander. It typically affects both eyes and is accompanied by intense itching and watery discharge.
Environmental Factors
Exposure to smoke, chemicals, or pollutants can also lead to conjunctivitis.
Contact Lenses and Contamination
Wearing contact lenses for extended periods or improper cleaning can cause pink eye due to bacterial contamination.
Medications and Reactions
Certain medications or eye drops can cause an allergic reaction, leading to pink eye symptoms.
Diagnosing Pink Eye
Clinical Evaluation
A thorough examination by an eye care professional is essential to diagnose pink eye accurately. This includes a detailed medical history and a physical examination of the eyes.
Laboratory Tests
In some cases, laboratory tests of eye secretions may be necessary to identify the specific cause and determine the appropriate treatment.
Treatment of Pink Eye
Over-the-Counter Treatments
For mild cases, over-the-counter eye drops and antihistamines can provide relief from symptoms.
Prescription Medications
Depending on the cause, a doctor may prescribe antibiotic eye drops or ointments for bacterial infections or antiviral medications for viral conjunctivitis.
Home Remedies
Applying a warm compress, maintaining good hygiene, and avoiding irritants can help alleviate symptoms.

Regular hand washing, avoiding touching the eyes, and using clean towels can prevent the spread of pink eye.
