The mere mention of pink eye in a daycare or school environment can send parents rushing to their primary care doctor for an evaluation. Most everyone knows that pink eye can be highly contagious, spreading rapidly through daycares, classrooms, and homes.
However, despite how common pink eye is, it is still widely misunderstood. Understanding the facts about this infection can help you to recognize when medical care is necessary. Here are a few basic facts that everyone should know about pink eye infections.
Pink Eye Is Not Always Contagious
Although pink eye's reputation for being highly contagious is not inaccurate, it's also incomplete. Pink eye can be caused by a variety of things, and some cases of pink eye are not contagious at all.
The most common strain of pink eye is caused by adenovirus. Adenovirus is the cause of things such as the flu, colds, and other respiratory illnesses. When infected mucus reaches your eyes, this can cause pink eye. A pink eye infection caused by adenovirus is highly contagious and can spread rapidly throughout your home if you don't take precautions and seek treatment.
Bacterial infections, including sinus infections and bronchitis, can also cause pink eye. Since bacteria can spread just like viruses do, a bacterial pink eye infection can also be contagious.
Some cases of pink eye are not contagious at all, however. For example, pink eye can result from allergies to dust, animal hair, pollen, and even wearing contacts. Since allergies and chemical exposures are not things that can spread from person to person, there's no risk of these pink eye cases being contagious.
In addition, exposure to certain chemicals can cause pink eye. Chlorine, smoke, and personal hygiene products can all cause pink eye cases in some situations.
Pink Eye Is More Than Just Red Eyes
Understanding what causes pink eye is a good place to start, but if you are unable to recognize the symptoms, you will not necessarily know when to see your doctor. Although eye redness is the most common and most well-known symptom of pink eye, it is not the only one. There are other symptoms to watch for as well.
For example, one of the earliest signs of a pink eye infection is irritation in your eye. While it may not necessarily be painful, it may be uncomfortable. Your eye could feel itchy, or it may just feel irritated and sore.
Pink eye also causes discharge from your eyes. This discharge can be substantial enough that, especially overnight, it can cause your eye to stick closed. You may also notice some eye swelling as well.
Pink Eye Treatment Varies
Many people mistakenly believe that all cases of pink eye will resolve on their own and need no treatment. Others panic at the slightest symptom of pink eye and rush to the doctor. The truth is that both are partially right. Seeing your doctor at the first signs of pink eye is important for identifying the source of the condition for proper treatment.
Some cases of pink eye, such as viral and irritant-caused cases, will resolve on their own. When the irritant is gone, irritant-triggered pink eye will resolve in a day or two. Viral pink eye, much like the common cold, needs to run its course. You may be able to get antiviral eye drops from your doctor for this, though, if the symptoms are particularly severe.
However, bacterial pink eye often needs to be treated with antibacterial eye drops to help the infection clear up. In addition, allergy-related pink eye is important to address because you may need to identify the source allergen to help avoid it in the future.
Warm compresses on your eye, lubricating eye drops, and lots of hand-washing are important for managing pink eye symptoms at home.
