Pink Eye Treatment: How to Tell If It Is Viral, Bacterial, or Allergic (and What to Do Next)

You woke up with a red, crusty, itchy eye and the first thought is pink eye. But did you know there are three different types — and each one requires a different approach? Getting the right diagnosis saves you time, money, and the frustration of using the wrong treatment.

The Three Types of Pink Eye

Viral Conjunctivitis (Most Common)

Caused by the same viruses that cause colds. Both eyes are usually affected. Discharge is watery and clear. Highly contagious for 10-14 days. Does not respond to antibiotic drops — it resolves on its own in 1-2 weeks. Cool compresses and artificial tears help manage symptoms.

Bacterial Conjunctivitis

Caused by bacteria — often Staphylococcus or Streptococcus. Usually starts in one eye and may spread to the other. Produces thick, yellow or green discharge that crusts overnight. Requires prescription antibiotic eye drops to clear the infection. With treatment, symptoms improve within 24-48 hours.

Allergic Conjunctivitis

Triggered by allergens like pollen, dust mites, or pet dander. Both eyes are affected simultaneously. Intense itching is the hallmark symptom. Watery discharge, often with puffy eyelids. Responds to antihistamine eye drops and avoiding the trigger. Very common in South Florida due to year-round allergens.

Why Diagnosis Matters

Using antibiotic drops for viral pink eye does nothing and wastes money. Using allergy drops for bacterial pink eye lets the infection worsen. Only a medical provider can reliably distinguish between the types through clinical examination. At TrufaMED Urgent Care, your provider examines your eyes, reviews your symptoms, and prescribes the correct treatment for your specific type.

When to See a Doctor for Pink Eye

Visit urgent care if you have moderate to severe eye pain, not just irritation. Your vision is blurred or you are sensitive to light. Symptoms are not improving after 3-4 days. You have thick green or yellow discharge. You wear contact lenses — infections can be more serious. Your child's school requires a doctor's note for return.

Preventing the Spread

Viral and bacterial pink eye are highly contagious. Wash your hands frequently and avoid touching your eyes. Do not share towels, pillowcases, or eye makeup. Replace contact lens cases and solution. Stay home from work or school until discharge clears.
