Understanding what causes pink eye can help you avoid getting infected and spreading it to others. Eyes on Hayden has prepared some of the causes of pink eye.

What is pink eye?

Pink eye, also known as conjunctivitis, is an infection or inflammation of the conjunctiva. Conjunctiva is the membrane that outlines the white part of the eye. Pink eye is associated with symptoms like redness of the eyelids, irritation, itchiness, watery eyes, discharge, or puffy eyes.

Causes of Pink Eye

Although there are many causes of pink eye, the common types of conjunctivitis we see at our clinic include:

Viruses

Viruses are one of the common causes of pink eye.

Bacteria

Allergens

Other causes include:

• Irritants such as cosmetics, contact lenses, shampoos, pool chlorine, dirt, and smoke
