The conjunctiva is a lining that covers the inside of the eye lid and the white part of the eye. Conjunctivitis, also known as pink eye, occurs when this lining becomes irritated and inflamed. This infection is commonly caused by bacteria or viruses, but it can also result from other causes. While uncomfortable, pink eye almost never leads to lasting effects and resolves on its own in most cases.
Pink eye can affect one or both eyes. When affected by conjunctivitis, a person will typically experience:
While pink eye is unlikely to lead to more serious complications, its symptoms can also occur with other eye disorders. Accordingly, you must seek out medical treatment when symptoms occur to rule out more serious conditions.
In addition to bacteria and viruses, conjunctivitis can also result from an allergic reaction. In babies, it can occur because of a blocked tear duct, which prevents fluids from draining from the eyes efficiently. The condition can also result from getting an object stuck in the eye or being splashed in the eyes by a chemical irritant.
Pink eye often resolves on its own in about two to three weeks. Accordingly, doctors typically provide soothing eye drops to relieve symptoms until the condition passes. People can also use compresses to soothe redness and irritation. In the event eye irritation results from herpes simplex virus, medications may be administered. Medication can also be used to treat allergies.
Because the condition is highly contagious, good hygiene practices can also help avoid pink eye. Hand washing is key for preventing germs from entering the eyes. This is especially important for people who wear contact lenses. When drying the face, use of a clean towel is a must. Additionally, people should not share towels with one another. In the same token, eye drops and cosmetics should not be shared to prevent passing germs from one person to another.
