Bacterial conjunctivitis is usually accompanied by a severe yellow or green discharge that “glues” the eyes together, often with pain, burning or itching. In these cases, it’s important to see a doctor and take immediate steps to stop the infection from spreading to others.
People with bacterial pinkeye can typically return to school or work within 24 hours of starting an antibiotic.
Viral
The same respiratory virus that causes a sore throat, upper respiratory infection and even the common cold is also responsible for viral pinkeye. On rare occasions, it can be the result of the same virus that causes herpes. And like a common cold, viral conjunctivitis simply needs to run its course. Relieve symptoms can help relieve symptoms by applying a cold compress and using artificial tears as recommended by your doctor.
Most viral cases are associated with watery tears as opposed to a pus-like green or yellow discharge. Those with viral can usually return to school or work when symptoms start to subside, typically in within three to five days. Medicines are not usually used to treat viral pinkeye, so it is important to prevent the spread of the infection.
Irritants
Pinkeye can be caused by outside irritants, including soap or shampoo, dirt, chlorine from a swimming pool, and in severe cases, chemical contact. Wash the irritated eye with warm water for at least five minutes to flush the irritant away. Avoid further exposure to the irritating substances. Your eyes should begin to improve within four hours after washing away the substance. If not, call a doctor.
Allergic
Allergy-associated conjunctivitis should be checked out by your ophthalmologist and an allergist. It may disappear completely when the allergy is treated with antihistamines or when the allergen is removed. You can relieve symptoms temporarily by applying a cold compress on closed eyes.
